2.6 Login Router

Firstly, IP address of PC should be changed to ensure it is within a same network segment as the device in the following two methods: automatic acquisition of IP address and static IP address. Proxy server (if any) should be cancelled for PC management settings. After setting the IP address of supervisory PC and ensuring there is no proxy server, the device can be logged in via web page.

I. Automatic acquisition of IP address (recommended)

Please set the supervisory computer to "automatic acquisition of IP address" and "automatic acquisition of DNS server address" (default configuration of computer system) to let the device automatically assign IP address for supervisory computer.

II. Set a static IP address

Set the IP address of supervisory PC (such as 192.168.2.2) and FE interface of device in same network segment (initial IP address of FE interface of device: 192.168.2.1, subnet mask: 255.255.255.0).

III. Cancel the Proxy Server

If the current supervisory PC uses a proxy server to access the Internet, it is required to cancel the proxy service. In the browser window, select "tools>>Internet options" and "connection" page and click the button of LAN Settings to enter "LAN Settings" window interface. Please confirm if the option "Use a Proxy Server for LAN" is checked; if it is checked, please cancel and click the button <OK>.

IV. Log in/exit Web settings page

Operate Web browser and enter http://192.168.2.1 in address bar (please look at the nameplate at the bottom of the device for login credentials). Click "exit" at the top right corner of Web interface and exit setting page after confirmation.

Note:

At the same time, the router allows up to four users to manage through the Web setting page. When multi-user management is implemented for the router, it is suggested not to conduct configuration operation for the router at the same time; otherwise it may lead to inconsistent data configuration.

For security, you are suggested to modify the default login password after the first login and safe keep the password information.

III. Web Configuration

3.1 Management

The management includes 12 function modules: system, system time, management access, AAA, configuration management, SNMP, alarm, system log, system upgrade, reboot, network management platform and GPS locating information.

3.1.1 System

Here, system and network state and system time of synchronizing device and PC can be checked and router WEB configuration interface language can be set as well as the name of mainframe of router can be customized. Configuration interface can be directly entered via "Settings" after clicking Cellular1, Fastethernet 0/1 and Fastethernet 0/2 under network state.

3.1.2 System Time

To ensure the coordination between this device and other devices, user is required to set the system time in an accurate way since this function is used to configure and check system time as well as system time zone. System time is allowed to be set as any expected value after Year 2000 manually. Users can also use SNTP to achieve time synchronization of all devices equipped with a clock on network so as to provide multiple applications based on synced time.

SNTP Servers List
Server Address	SNTP server address (domain name /IP), maximum to set 10 SNTP servers	None
Port	The service port of SNTP server	123

Attention:

Before setting a SNTP server, users should ensure SNTP server reachable. Especially when the IP address of SNTP server is domain, users should ensure DNS server has been configured correctly.

Users should configure either Source Interface or source IP. Source Interface and source IP cannot be configured at the same time.

When setting multiple SNTP servers, system will poll all SNTP servers until an available SNTP server found.

3.1.3 Admin Access

Admin Access allows create users, modify users and management services. Users include Super User and Common User:

Super user: only one super user automatically created by the system, username adm. It has all access rights to the router.
Common user: created by super user. Common users can view router configurations but don not have access to change configurations.

User right includes three levels:

User right 1-11: only access to parameters check rather than configuration;
User right 12-14: access to configure LAN IP, system time setting, basic configuration of firewall, virtual IP mapping table, system log, certificate application, access control, static routing, system upgrade and tool-ping detection. Others shown as grey, which can be checked but the configuration can not be modified;
User right 15: access to the check and configuration for all parameters.

Management services include HTTP, HTTPS, TELNET and SSH.

HTTP: users can log in the device via HTTP and access and control it through Web after clicking the button of "enable".
HTTPS: HTTPS (security version of hypertext transfer protocol) is HTTP which supports SSL.
TELNET: after clicking the button of "enable", users can provide remote login via network. Depending on Server/Client, Telnet Client could send request to Telnet server which provides Telnet services. The device supports Telnet Client and Telnet Server.
SSH: Based on the RSA certification or the measures of encrypting username password and data transmission via encryption algorithm DES, 3DES and AES128, secure remote login can be provided via insecure network. IR900 only supports SSH server and it can receive many connections from SSH client.

3.1.4 AAA

AAA access control is used to control visitors and corresponding services available as long as access is allowed. Same method is adopted to configure three independent safety functions. It provides modularization methods for following services:

Authentication: verify whether the user is qualified to access to the network.
Authorization: related services available.
Charging: records of the utilization of network resources.

1) Radius

UDP protocol, generally applied in various network environments with higher requirements on security and that permit remote user access.

2) Tacacs+

TCP protocol, mainly used for authentication, authorization and charging of access users and terminal users adopting PPP and VPDN.

3) LDAP

LDAP, simple as a table, only requires username, command, and something else, which makes it very simple.

Table 3-1-3 LDAP Parameter Description

Parameters	Description	Default
Name	Customized server name	None
Server Address	Server address (domain name / IP)	None
Port	Consistent with the server port	None
Base DN	The top of LDAP directory tree	None
Username	Username accessing the server	None
Password	Password accessing the server	None
Security	Encryption mod: None, SSL, StartTLS	None
Verify opposite end	Click to enable	Unopened

4) AAA

AAA supports following authentication ways:

None: with great confidence to users, legal check omitted, generally not recommended.
Local: Have user’s information stored on NAS. Advantages: rapidness, cost reduction. Disadvantages: storage capacity limited by hardware.
Remote: Have user’s information stored on authentication server. Radius, Tacacs+ and LDAP supported for remote authentication.

AAA supports following authorization ways:

None: authorization rejected.
Local: authorization based on relevant attributions configured by NAS for local user’s account.
Tacacs+: authorization done by Tacacs+ Server.
Radius Authentication Based: authentication bonded with authorization, authorization only by Radius not allowed.
LDAP Authorization

Attention:

Authentication 1 should be set consistently with Authorization 1; Authentication 2 should be set consistently with Authorization 2; Authentication 3 should be set consistently with Authorization 3.

When configure radius, Tacacs+, local at the same time, priority order follow: 1 >2 >3.

3.1.5 Configuration Management

Here you can back up the configuration parameters, import the desired parameters configuration backup and reset the router.

Table 3-1-4 Configuration Management Parameter Description

Parameters	Description	Default
Browse	Choose the configuration file	None
Import	Import configuration file to router startup-config	None
Backup running-config	Backup running-config file to host.	None
Backup startup-config	Backup startup-config file to host.	None
Automatically save modified configuration	Decide whether to automatically save configuration after modify the configuration.	On
Restore default configuration	Restore factory configuration	None

Attention:

Validity and order of imported configurations should be ensured. When importing the configuration, the system will filter incorrect configuration commands, and save the correct configuration as startup-config, when system restarts, it will orderly execute theses configurations. If the configuration files didn’t be arranged according to effective order, the system won’t enter the desired state.

In order not to affect current system running, when performing the import configuration and restoring the default configuration, and the new configuration will take effect after rebooting the router.

3.1.6 SNMP

Administrator is required to carry out configuration and management of all devices in the same network, which are scattered, making onsite device configuration impracticable. Moreover, in case that those network devices are supplied by different manufacturers and each manufacturer has its independent management interfaces (for example, different command lines), the workload of batch configuration of network devices will be considerable. Therefore, under such circumstances, traditional manual ways will result in lower efficiency at higher cost. At that time, network administrator would make use of SNMP to carry out remote management and configuration of attached devices and achieve real-time monitoring.

Figure showing how to manage devices through SNMP is shown below:

To configure SNMP in networking, NMS, a management program of SNMP, should be configured at the Manager. Meanwhile, Agent should be configured as well.

Through SNMP:

NMS could collect status information of devices whenever and wherever and achieve remote control of devices under management through Agent.
Agent could timely report current status information of device to NMS. In case of any problem, NMS will be notified immediately.

Currently, SNMP Agent of device supports SNMPv1, SNMPv2c and SNMPv3 version. SNMPv1 and SNMPv2c employ community name authentication; SNMPv3 employs the authentication encryption way of username and password.

3.1.7 Alarm

Alarm function is a way which is provided for users to get exceptions of device, which can make the users find and solve exceptions as soon as possible. When abnormality happened, device will send alarm. User can choose many kinds of exceptions which system defined and choose appropriate notice way to get these exceptions. All the exceptions should be recorded in alarm log so that users can troubleshoot problems.

According to the type of alarm, it can be divided into system alarm and port alarm.

System Alarm: It produces because of system or environment happened to some exception, divided into hot start, cold start and insufficient memory.
Port Alarm: It produces because of the network interface is up or down, divided into LINK-UP, LINK-DOWN.

Alarm status:

Raise: Alarm is not confirmed
Confirm: Alarm is temporarily unable to be resolved by users
All: All alarms occurred

Alarm level:

EMERG: Device occurs some faults, it could lead to the system restart.
CRIT: Device occurs some faults which are unrecoverable.
WARN: Device occurs some faults which could affect system function.
NOTICE: Device occurs some faults which could affect system properties.
INFO: Device occurs some normal events.

The following operations are feasible via alarm configuration dialog:

On the “Alarm Status” page, you can view all the alarms since system was power on.
On the “Alarm Input” page, you can define alarm types which you concern.
On the “Alarm Output” page, you can set the way of alarm notice. Log record is in a default output way. When configuring the function and if there is an alarm, the system will send the alarm from email address sending alarm to objective email address, which is not recommended.
On the “Alarm Map” page, you can map the alarm type which you concern to one or more alarm notice way. Alarm Map includes two type: CLI (console port) and Email. If Email map is required to be enabled, it should be enabled at Alarm Output part and configure email address.

3.1.8 System Log

System Log includes massive information about network and devices, including operating status, configuration changes and so on. Remote log server is feasible, and router will upload all system log to remote log server, which requires the cooperation of remote log software (such as ) of mainframe.

Attention:

When downloading system diagnosis records, configuration information of the router will be also downloaded.

3.1.9 System Upgrading

The upgrading process can be divided into two steps. In the first step, upgrading files will be written in backup firmware zone, e.g., the process in the section of System Upgrading; in second step: files in backup firmware zone will be copied to main firmware zone, which should be carried out during system restart. During software upgrading, any operation on web page is not allowed, otherwise software upgrading may be interrupted.

3.1.10 Reboot

Please save the configurations before reboot, otherwise the configurations that are not saved will be lost after reboot.

3.1.11 Device Management

Device Management is a software platform to manage equipment. The equipment can be managed and operated via software platform when Device Management is started so that the internet can be in efficient operation. For instance, the operating status of equipment can be checked, equipment software can be upgraded, equipment can be restarted, configuration parameters can be sent down to equipment, and transmitting control or message query can be realized on equipment via Device Management.

Backup SIM Timeout	From beginning to switch to the backup card counting, exceeds the timeout, router will switch to the primary card	0

3.2.3 ADSL Dialing (PPPoE)

PPPoE is a point-to-point protocol over Ethernet. User has to install a PPPoE Client on the basis of original connection way. Through PPPoE, remote access devices could achieve the control and charging of each accessed user.

Connection mode at Ethernet port must be PPPoE, namely, configuration interface must be the PPPoE Client.

Table 3-2-4 Dialing Port Parameter Description

Parameters	Description	Default
Pool ID	User define, easy to memorize and manage	None
Interface	Fastethernet0/1 and Fastethernet0/2 are choosable	Fastethernet0/1
PPPoE List
ID	User define, easy to memorize and manage	1
Pool ID	Same as the dialup pool	None
Authentication Type	Auto, PAP, CHAP	Auto
User Name	Operators provide the relevant parameters	None
Password	Operators provide the relevant parameters	None
Local IP Address	Set the IP address assigned for Ethernet interface	None
Remote IP Address	Set the IP of remote device	None

3.2.4 Loopback Interface

Loopback interface is used to take place of router’s ID since as long as an active interface is used, when it turns to DOWN, ID of router has to be selected again, resulting to long convergence time of OSPF. Therefore, generally loopback interface is recommended as the ID of router.

Loopback interface is a logic and virtual interface on router. Under default conditions, a router has no loopback interface which can be created for a number as required. Those interfaces are the same as physical interfaces on router: addressing information allocated, including their network number in router upgrade and even IP connection could be terminated on them.

Table 3-2-5 Loopback Interface Parameter Description

Parameters	Description	Default
IP Address	Users can not change	127.0.0.1
Netmask	Users can not change	255.0.0.0
Multi-IP Settings	Apart from above IP, user can configure other IP address	N/A

Attention:

Since the loopback interface monopolizes one IP address, subnet mask is generally suggested to be 255.255.255.255 for the purpose of saving resources.

3.2.5 DHCP Service

DHCP adopts Client/Server communication mode. Client sends configuration request to Server which feeds back corresponding configuration information, including distributed IP address to the Client to achieve the dynamic configuration of IP address and other information.

The duty of DHCP Server is to distribute IP address when Workstation logs on and ensure each workstation is supplied with different IP address. DHCP Server has simplified some network management tasks requiring manual operations before to the largest extent.
As DHCP Client, the device receives the IP address distributed by DHCP server after logging in the DHCP server, so the Ethernet interface of the device needs to be configured into an automatic mode.

Table 3-2-6 DHCP Server Parameters

Parameters	Description	Default
Enable	On/Off	Off
Interface	Fastethernet 0/1 and Fastethernet 0/2 available	Fastethernet 0/1
Starting Address	Dynamical distribution of starting IP address	N/A
Ending Address	Dynamical distribution of ending IP address	N/A
Lease	Dynamical distribution of IP validity	1440
DNS Server	One or two, or None	N/A
WINS	Setup of WINS, generally left blank	N/A
Static IP Setup
MAC Address	Set up a static specified DHCP’s MAC address (different from other MACs to avoid confliction)	0000.0000.0000
IP Address	Set up a static specified IP address (within the scope from start IP to end IP)	N/A

Attention:

If the host connected with router chooses to obtain IP address automatically, then such service must be activated. Static IP setup could help a certain host to obtain specified IP address.

InRouter900 F0/2 enable DHCP server by default; obtaining IP address automatically is suggested.

Generally, DHCP data packet is unable to be transmitted through router. That is to say, DHCP Server is unable to provide DHCP services for two or more devices connected with a router remotely. Through DHCP relay, DHCP requests and response data packet could go through many routers (Broadband Router).

Table 3-2-7 DHCP Transfer Parameters

Parameters	Description	Default
Enable	On/Off	Off
DHCPSever	Set DHCP server; up to 4 servers can be configured	N/A
Source address	Address of the interface connected to the DHCP server	N/A

3.2.6 DNS Services

DNA (Domain Name System) is a DDB used in TCP/IP application programs, providing switch between domain name and IP address. Through DNS, user could directly use some meaningful domain name which could be memorized easily and DNS Server in network could resolve the domain name into correct IP address.

The device supports to achieve following two functions through domain name service configuration:

DNS Server: for dynamic domain name resolution.
DNS relay: the device, as a DNS Agent, relays DNS request and response message between DNS Client and DNS Server to carry out domain name resolution in lieu of DNS Client.

Manually set the DNS, use DNS via dialing if it is empty. Generally, it needs to set this only when using the static IP at the WAN port.

Table 3-2-8 DNS Parameters

Parameters	Description	Default
Primary DNS	User define Primary DNS address	N/A
Secondary DNS	User define Secondary DNS address	N/A

DNS forwarding is open by default. You can set the specified [Domain Name <=> IP Address] to let IP address match with the domain name, thus allowing access to the appropriate IP through accessing to the domain name.

Table 3-2-9 DNS Transfer Parameters

Parameters	Description	Default
Enable DNS Relay	On/Off	On
Host	Domain Name	N/A
IP Address 1	Set IP Address 1	N/A
IP Address 2	Set IP Address 2	N/A

Attention:

Once DHCP is turned on, DNS relay will be turned on as default and can’t be turned off; to turn off DNS rely, DHCP Server has to be closed firstly.

3.2.7 Dynamic Domain Name

DDNS maps user's dynamic IP address to a fixed DNS service. When the user connects to the network, the client program will pass the host’s dynamic IP address to the server program on the service provider’s host through information passing. The server program is responsible for providing DNS service and realizing dynamic DNS. It means that DDNS captures user's each change of IP address and matches it with the domain name, so that other Internet users can communicate through the domain name. What end customers have to remember is the domain name assigned by the dynamic domain name registrar, regardless of how it is achieved.

DDNS serves as a client tool of DDNS and is required to coordinate with DDNS Server. Before the application of this function, a domain name shall be applied for and registered on a proper website such as www.3322.org. After the settings of dynamic domain name on WBR204n, a corresponding relationship between the domain name and IP address of WAN port of the device is established.

IR900 DDNS service types include DynAccess, QDNS (3322)-Dynamic, QDNS (3322)-Static, DynDNS-Dynamic, DynDNS-Static and NoIP.

Table 3-2-10 DDNS Parameters

Parameters	Description	Default
Method Name	User define	None
Service Type	Select the domain name service providers	None
User Name	User name assigned in the application for dynamic domain name	None
Password	Password assigned in the application for dynamic domain name	None
Host Name	Host name assigned in the application for dynamic domain name	None
Method	The update method of specified interface	None

Attention:

If the IP address obtained via router dialing is a private address, the dynamic DNS function is not available.

3.2.8 SMS

SMS permits message-based reboot and manual dialing. Configure Permit action to Phone Number and click <Apply & Save>. After that you can send “reboot” command to restart the device or “cellular 1 ppp up/down” to redial or disconnect the device.

3.2.10 WLAN Interface

WLAN refers to Wireless Local Area Network. WLAN has two types of interfaces, the Access point and the Client.

Table 3-2-13 WLAN Parameters

Parameters	Description	Default
Access point
SSID broadcast	After turning on, use can search the WLAN via SSID name	Turn on
RF type	Six type for options: 802.11g/n, 802.11g, 802.11n, 802.11b, 802.11b/g , 802.11b/g/n	802.11g/n
Channel	Select the channel	11
SSID	SSID name defined by user	InRouter900
Authentication method	Four authentication methods for option: open type, shared type, WPA-PSK and WPA2-PSK	Open type
Encryption	Support NONE, WEP40 and WEP104 as per different authentication methods	NONE
Wireless bandwidth	Both 20MHz and 40MHz for selection	20MHz
Maximum Number of Clients	User defined (at most 128)	N/A
Client
SSID	Fill in the name of the SSID to be connected	N/A
Authentication method	Stay the same with the authentication method of the SSID to be connected	Open type
Encryption	Stay the same with the encryption method of the SSID to be connected	NONE

The device usually needs three steps of setting when used as Client:

Step I: Click the “Network>>Dial interface” menu in the navigation tree to enter the “ail interface”, close the dial interface. This step will be unnecessary when the device is without a module. Instead, directly operate the second step.

Step II: Click the “Network>>WLAN interface” menu in the navigation tree to enter the “WLAN interface”. Select “Client” for the interface type and configure relevant parameters.

Step III: Click the “Setup Wizard>>New WLAN” menu in the navigation tree to enter the “New WLAN” interface. Select fastethernet 0/1 as the interface; the type can be either the dynamic address (DHCP) or static IP. If the static IP is selected, it needs to configure relevant parameters in the “IP setting” interface and the Client IP address must be the same with that of the AP network segment.

The scanning function of the SSID can be started only when selecting the Client at the WLAN interface type. In the “SSID scanning” interface, all available SSID names as well as the connection status of the device as Client will be displayed.

3.3 Link Backup

3.3.1 SLA

Basic principles of InHand SLA:

1.Object track: Track the reachability of the specified object.

2. SLA probe: The object track function can use InHand SLA to send different types of detections to the object.

3. Policy-based routing using route mapping table: It associates the track results with the routing process. 4. Using static routing and track options.

SLA Configuration Steps:

Step 1: Define one or more SLA operations (detection).

Step 2: Define one or more track objects to track the status of SLA operation. Step 3: Define measures associated with track objects.

Parameters	Description	Default
Index	SLAindex orID	1
Type	Detection type, default is icmp-echo, the user cannot change	icmp-echo

3.3.2 Track Module

Track is designed to achieve linkage consisting of application module, Track module and monitoring module. Track module is located between application module and monitoring module with main functions of shielding the differences of different monitoring modules and providing uniform interfaces for application module.

Track Module and Monitoring Module Linkage

Through configuration, the linkage relationship between Track module and monitoring module is established. Monitoring module is responsible for detection of link status, network performance and notification to application module of detection results via Track module so as to carry out timely change of the status of Track item:

Successful detection, corresponding track item is Positive
Failed detection, corresponding track item is Negative

Track Module and Application Module Linkage

Through configuration, the linkage relationship between Track module and application module is established. In case of any changes in track item, a notification requiring correspondent treatment will be sent to application module.

Currently, application modules which could achieve linkage with track module include: VRRP, static routing, strategy-based routing and interface backup.

Under certain circumstances, once any changes in Track item are founded, if a timely notification is sent to application module, then communication may be interrupted due to routing’s failure in timely restoration and other reasons. Under such circumstances, user to configure that once any changes take place in Track item, delays a period of time to notify the application module.

Table 3-3-2 Track Module Parameters

Parameters	Description	Default
Index	Track index or ID	1
Type	Default “sla”,User cannot change	sla
SLA ID	Defined SLA Index or ID	None
Interface	Detect interface’s up/down state	cellular 1
Negative Delay	In case of negative status, switching can be delayed based on the set time (0 represents immediate switching), rather than immediate switching.	0
Positive Delay	In case of failure recovery, switching can be delayed based on the set time (0 represents immediate switching), rather than immediate switching.	0

3.3.3 VRRP

Default route provides convenience for user’s configuration operations but also imposes high requirements on stability of the default gateway device. All hosts in the same network segment are set up with an identical default route with gateway being the next hop in general. When fault occurs on gateway, all hosts with the gateway being default route in the network segment can’t communicate with external network.

Increasing exit gateway is a common method for improving system reliability. Then, the problem to be solved is how to select route among multiple exits. VRRP (Virtual Router Redundancy Protocol) adds a set of routers that can undertake gateway function into a backup group to form a virtual router. The election mechanism of VRRP will decide which router to undertake the forwarding task and the host in LAN is only required to configure the default gateway for the virtual router.

VRRP will bring together a set of routers in LAN. It consists of multiple routers and is similar to a virtual router in respect of function. According to the vlan interface ip of different network segments, it can be virtualized into multiple virtual routers. Each virtual router has an ID number and up to 255 can be virtualized.

VRRP has the following characteristics:

Virtual router has an IP address, known as the Virtual IP address. For the host in LAN, it is only required to know the IP address of virtual router, and set it as the address of the next hop of the default route.
Host in the network communicates with the external network through this virtual router.
1 router will be selected from the set of routers based on priority to undertake the gateway function. Other routers will be used as backup routers to perform the duties of gateway for the gateway router in case of fault of gateway router, thus to guarantee uninterrupted communication between the host and external network

Monitor interface function of VRRP better expands backup function: the backup function can be offered when interface of a certain router has fault or other interfaces of the router are unavailable.

When interface connected with the uplink is at the state of Down or Removed, the router actively reduces its priority so that the priority of other routers in the backup group is higher and thus the router with highest priority becomes the gateway for the transmission task.

Table 3-3-3 VRRP Parameters

Parameters	Description	Default
Enable	Enable/Disable	Enable
Virtual Route ID	User define Virtual Route ID	None
Interface	Configure the interface of Virtual Route	None
Virtual IP Address	Configure the IP address of Virtual Route	None
Priority	The VRRP priority range is 0-255 (a larger number indicates a higher priority). The router with higher priority will be more likely to become the gateway router.	100
Advertisement Interval	Heartbeat package transmission time interval between routers in the virtual ip group	1
Preemptive Mode	If the router works in the preemptive mode, once it finds that its own priority is higher than that of the current gateway router, it will send VRRP notification package, resulting in re-election of gateway router and eventually replacing the original gateway router. Accordingly, the original gateway router will become a Backup router.	Enable
Track ID	Trace Detection, select the defined Track index or ID	None

3.3.4 Interface Backup

Interface backup refers to backup relationship formed between appointed interfaces in the same equipment. When service transmission can’t be carried out normally due to fault of a certain interface or lack of bandwidth, rate of flow can be switched to backup interface quickly and the backup interface will carry out service transmission and share network flow so as to raise reliability of communication of data equipment.

When link state of main interface is switched from up to down, system will wait for preset delay first instead of switching to link of backup interface immediately. Only if the state of main interface still keeps down after the delay, system will switch to link of backup interface. Otherwise, system will not switch.

After link state of main interface is switched from down to up, system will wait for preset delay first instead of switching back to main interface immediately. Only if state of main interface still keeps up after the delay, system will switch back to main interface. Otherwise, system will not switch.

Table 3-3-4 Interface Backup Parameters

Parameters	Description	Default
Primary Interface	The interface being used	cellular 1
Backup Interface	Interface to be switched	cellular 1
Start-up Delay	Set how long to wait for the start-up tracking detection policy to take effect	60
Up Delay	When the primary interface switches from failed detection to successful detection, switching can be delayed based on the set time (0 represents immediate switching), rather than immediate switching.	0
Down Delay	When the primary interface switches from successful detection to failed detection, switching can be delayed based on the set time (0 represents immediate switching), rather than immediate switching.	0
Track ID	Trace Detection, select the definedTrack index or ID	None

3.4 Routing

3.4.1 Static Route

Generally, user does not need to set this. Static routing is a special routing that requires your manual setting. After setting static routing, the package for the specified destination will be forwarded according to the path designated by you.

Table 3-4-1 Static Route Parameters

Parameters	Description	Default
Destination address	Enter the destination IP address need to be reached	0.0.0.0
Subnet Mask	Enter the subnet mask of destination address need to be reached	0.0.0.0
Interface	The interface through which the data reaches the destination address	Cellular1
Gateway	IP address of the next router to be passed by before the input data reaches the destination address	None
Distance	Priority, smaller value contributes to higher priority	None
Track ID	Select the definedTrack index or ID	None

3.4.2 Dynamic Routing

The gateway protocol used in the autonomous system (AS) consists of the OSPF protocol and the RIP protocol.

1) RIP

RIP is mainly used for smaller networks. RIP uses Hop Count to measure the distance to the destination address and it is called RoutingCost. In RIP, the hop count from the router to its directly connected network is 0 and the hop count of network to be reached through a router is 1 and so on. In order to limit the convergence time, the specified RoutingCost of RIP is an integer in the range of 0~15 and hop count larger than or equal to 16 is defined as infinity, which means that the destination network or host is unreachable. Because of this limitation, the RIP is not suitable for large-scale networks. To improve performance and prevent routing loops, RIP supports split horizon function. RIP also introduces routing obtained by other routing protocols.

It is specified in RFC1058 RIP that RIP is controlled by three timers, i.e. Period update, Timeout and Garbage-Collection.

Each router that runs RIP manages a routing database, which contains routing entries to reach all reachable destinations. The routing entries contain the following information:

Destination address: IP address of host or network.
Address of next hop: IP address of interface of the router’s adjacent router to be passed by on the way to reach the destination.
Output interface: The output interface for the router to forward package.
Routing Cost: Cost for the router to reach the destination.
Routing time: The time from the last update of router entry to the present. Each time the router entry is updated, the routing time will be reset to 0.

Table 3-4-2 RIP Parameters

Parameters	Description	Default
Enable	Enable/ Disable	Disable
Update timer	It defines the interval to send routing updates	30
Timeout timer	It defines the routing aging time. If no update package on a routing is received within the aging time, the routing’s Routing Cost in the routing table will be set to 16.	180
Clear Timer	It defines the time from the time when the RoutingCost of a routing becomes 16 to the time when it is deleted from the routing table. In the time of Garbage-Collection, RIP uses 16 as the RoutingCost for sending updates of the routing. In case of timeout of Garbage-Collection and the routing still has not been updated, the routing will be completely removed from the routing table.	120
Version	Version number of RIP	V2
Network	The first IP address and subnet mask of the segment	None
Advanced Options
Filter In	Only send RIP packets do not receive RIP packets	Disable
Filter Out	RIP packets sent to the default routing interface	Disable
Default-Information Originate	Default information will be released	Disable
Default Metric	The default overhead of the router reach to destination	1
Distance	Set the RIP routing administrative distance	120
Redistribute router	Introduce the directly connected, static, OSPF protocols into the RIP protocol	Disable
Passive Default	Interface only receives RIP packets, do not send RIP packets	None
Neighbour	For neighbouring routers, after configuring neighbours, rip package will only be sent to neighbouring routers	None

2) OSPF

Open Shortest Path First (OSPF) is a link status based interior gateway protocol developed by IETF.

Router ID

If a router wants to run the OSPF protocol, there should be a Router ID. Router ID can be manually configured. If no Router ID is configured, the system will automatically select one IP address of interface as the Router ID.

The selection order is as follows:

If a Loopback interface address is configured, then the last configured IP address of Loopback interface will be used as the Router ID;
If no LoopBack interface address is configured, choose the interface with the biggest IP address from other interfaces as the Router ID.

OSPF has five types of packets:

Hello Packet
DD Packet (Database Description Packet)
LSR packet (Link State Request Packet)
LSU Packet (Link State Update Packet)
LSAck packet (Link State Acknowledgment Packet)

Neighbour and Neighbouring

After the start-up of OSPF router, it will send out Hello packets through the OSPF interface. Upon receipt of Hello packet, OSPF router will check the parameters defined in the packet. If both are consistent, a neighbour relationship will be formed. Not all both sides in neighbour relationship can form the adjacency relationship. It is determined based on the network type. Only when both sides successfully exchange DD packets and LSDB synchronization is achieved, the adjacency in the true sense can be formed. LSA describe the network topology around a router, LSDB describe entire network topology.

Table 3-4-3 OSPF Parameters

Parameters	Description	Default
Enable	Enable/Disable	Disable
Router ID	RouterID of the originating the LSA	None
Advanced Options
Default Metric	The default overhead of the router reach to destination	None
Redistribute Router	Introduce the directly connected, static, RIP protocols into the OSPF protocol	Disable

Area ID	Area ID of router which originating LSA	None
Interface
Interface	The interface	None
Hello Interval	Send interval of Hello packet. If the Hello time between two adjacent routers is different, you can not establish a neighbour relationship.	None
Dead Interval	Dead Time. If no Hello packet is received from the neighbours, the neighbour is considered failed. If dead times of two adjacent routers are different, the neighbour relationship can not be established.	None
Network	Select OSPF network type	None
Priority	Set the OSPF priority of interface	None
Retransmit Interval	When the router notifies an LSA to its neighbour, it is required to make acknowledgement. If no acknowledgement packet is received within the retransmission interval, this LSA will be retransmitted to the neighbour.	None
Interface	The interface	None
Hello Interval	Send interval of Hello packet. If the Hello time between two adjacent routers is different, you can not establish a neighbour relationship.	None

3.4.3 Multicast Routing

Multicast routing sets up an acyclic data transmission route from data source end to multiple receiving ends, which refers to the establishment of a multicast distribution tree. The multicast routing protocol is used for establishing and maintaining the multicast routing and for relaying multicast data packet correctly and efficiently.

The basic is mainly to define the source of multicast routing.

Table 3-4-5 Basic Setup Parameters

Parameters	Description	Default
Enable	Open/Close	Close
Source	IP Address of Source	None
Netmask	Netmask of Source	255.255.255.0
Interface	Interface of Source	cellular1

IGMP, being a multicast protocol in Internet protocol family, which is used for IP host to report its constitution to any directly adjacent router, defines the way for multicast communication of hosts amongst different network segments with precondition that the router itself supports multicast and is used for setting and maintaining the relationship between multicast members between IP host and the directly adjacent multicast routing. IGMP defines the way for maintenance of member information between host and multicast routing in a network segment.

In the multicast communication model, sender, without paying attention to the position information of receiver, only needs to send data to the appointed destination address, while the information about receiver will be collected and maintained by network facility. IGMP is such a signalling mechanism for a host used in the network segment of receiver to the router. IGMP informs the router the information about members and the router will acquire whether the multicast member exists on the subnet connected with the router via IGMP.

Function of multicast routing protocol:

Discovering upstream interface and interface closest to the source for the reason that multicast routing protocol only cares the shortest route to the source.
Deciding the real downstream interface via (S, G). A multicast tree will be finished after all routers acquire their upstream and downstream interfaces with root being router directly connected with the source host and branches being routers directly connected via subnet with member discovered by IGMP.
Managing multicast tree. The message can be transferred once the address of next hop can be acquired by unicast routing, while multicast refers to relay message generated by source to a group.

Table 3-4-6 IGMP Parameters

Parameters	Description	Default
Upper port	The port connecting the upper-level network device	N/A
Lower port list
Lower port	The port connecting the lower terminal device	cellular 1
Upper port	The port connecting the upper-level network device	cellular 1

3.5 Firewall

The firewall function of the router implements corresponding control to data flow at entry direction (from Internet to local area network) and exit direction (from local area network to Internet) according to the content features of message (such as: protocol style, source/destination IP address, etc.) and ensures safe operation of router and host in local area network.

3.5.1 Access Control (ACL)

ACL, namely access control list, implements permission or prohibition of access for appointed data flow (such as prescribed source IP address and account number, etc.) via configuration of a series of matching rules so as to filter the network interface data. After message is received by port of router, the field is analyzed according to ACL rule applied on the current port. And after the special message is identified, the permission or prohibition of corresponding packet is implemented according to present strategy.

ACL classifies data packages through a series of matching conditions. These conditions can be data packages’ source MAC address, destination MAC address, source IP address, destination IP address, port number, etc.

The data package matching rules as defined by ACL can also be used by other functions requiring flow distinguish.

Table 3-5-1 AC Parameters

Parameters		Description							Default
Type		Standard ACL can prevent all the communication flow of some network or permit all the communication flow of some network or refuse all the communication flow of some protocol stack (like IP). Expanded ACL can provide more extensive control scope than standard ACL does. For instance, network manager can make use of expanded ACL instead of standard ACL to permit Web communication flow, refuse FTP and Telnet because the control of ACL is not as desired.							Expanded
ID		User self-defined number							No
Action		Permit/refuse							Permit
Agreement		ACP							Ip
Source address	IP	Source network address (blank in case of any configuration)							No
Source address wildcard mask		Radix-minus-one complement of mask in source network address							No
Destination address	IP	Destination network configuration)	address	(blank	in	case	of	any	No
Destination address wildcard mask		Radix-minus-one complement of mask in destination address							No
Writing log		Click starting and the log about access control will be recorded in the system after starting							Forbidden
Description		Convenient for recording parameters of access control							No
Network Interface List
Port name		Select the name of network interface							cellular1
Rule		Select the rules for in and out and management							none

3.5.2 NAT

NAT can achieve Internet access by multiple hosts within the LAN through one or more public network IP addresses. It means that few public network IP addresses represent more private network IP addresses, thus saving public network IP addresses.

Table 3-5-2 Network Address Translation (NAT) Parameters

Parameters	Description	Default
Action	SNAT: Source NAT: Translate IP packet's source address into another address DNAT: Destination NAT: Map a set of local internal addresses to a set of legal global addresses. 1:1NAT: Transfer IP address one to one.	SNAT
Source Network	Inside: Inside address Outside: Outside address	Inside
Translation Type	Select the Translation Type	IP to IP

Attention:

NAT rule is to apply ACL into address pool, and only address matched with ACL can be translated.

Private network IP address refers to the IP address of home network or mainframe, and IP address of public network refers to the only global IP address on the internet. RFC 1918 reserves 3 IP addresses for private network, as shown followed:

A: 10.0.0.0~10.255.255.255

B: 172.16.0.0~172.31.255.255

C: 192.168.0.0~192.168.255.255

The addresses in the three types above will not be distributed on the internet, so they can be used in companies or enterprises instead of being applied to operator or registration center.

3.5.3 MAC-IP Binding

If the default process in the basic setting of firewall is disabled, only hosts specified in MAC-IP can have an access to outer net.

Table 3-5-3 MAC-IP Binding Parameters

Parameters	Description	Default

3.6 QoS

QoS can control network traffic, avoid and manage network congestion, and reduce packet dropping rate. Some applications bring convenience to users, but they also take up a lot of network bandwidth. To ensure all LAN users can normally get access to network resources, IP traffic control function can limit the flow of specified host on local network.

QoS provides users with dedicated bandwidth and different service quality for different applications, greatly improving the network service capabilities. Users can meet various requirements of different applications like guaranteeing low latency of time-sensitive business and bandwidth of multimedia services.

QoS can guarantee high priority data frames receiving, accelerate high-priority data frame transmission, and ensure that critical services are unaffected by network congestion. IR900 supports four service levels, which can be identified by receiving port of data frame, Tag priority and IP priority.

3.7 VPN

VPN is for building a private dedicated network on a public network via the Internet. 'Virtuality" mainly refers to that the network is a logical network.

Two Basic Features of VPN:

Private: the resources of VPN are unavailable to unauthorized VPN users on the internet; VPN can ensure and protect its internal information from external intrusion.
Virtual: the communication among VPN users is realized via public network which, meanwhile can be used by unauthorized VPN users so that what VPN users obtained is only a logistic private network. This public network is regarded as VPN Backbone.

Build a credible and secure link by connecting remote users, company branches, partners to the network of the headquarters via VPN so as to realize secure transmission of data. It is shown in the figure below:

Fundamental Principle of VPN

The fundamental principle of VPN indicates to enclose VPN message into tunnel with tunneling technology and to establish a private data transmission channel utilizing VPN Backbone so as to realize the transparent message transmission.

Tunneling technology encloses the other protocol message with one protocol. Also, encapsulation protocol itself can be enclosed or carried by other encapsulation protocols. To the users, tunnel is logical extension of PSTN/link of ISDN, which is similar to the operation of actual physical link.

The common tunnel protocols include L2TP, PPTP, GRE, IPSec, MPLS, etc.

3.7.1 IPSec

A majority of data contents are Plaintext Transmission on the Internet, which has many potential dangers such as password and bank account information stolen and tampered, user identity imitated, suffering from malicious network attack, etc. After disposal of IPSec on the network, it can protect data transmission and reduce risk of information disclosure.

IPSec is a group of open network security protocol made by IETF, which can ensure the security of data transmission between two parties on the Internet, reduce the risk of disclosure and eavesdropping, guarantee data integrity and confidentiality as well as maintain security of service transmission of users via data origin authentication, data encryption, data integrity and anti-replay function on the IP level.

IPSec, including AH, ESP and IKE, can protect one and more date flows between hosts, between host and gateway, and between gateways. The security protocols of AH and ESP can ensure security and IKE is used for cipher code exchange.

IPSec can establish bidirectional Security Alliance on the IPSec peer pairs to form a secure and interworking IPSec tunnel and to realize the secure transmission of data on the Internet.

The local certificate is generally kept but the certificate of the opposite end may be kept or may be not (common situation); generally, both ends will send the request for “certificate request” when IPSEC is being connected. The ipsec server will send its certificate to the opposite end after having received this request. Always send certificate: Some ipsec server does not send a “certificate request” request and it has not place to keep the certificate send from the opposite end, so the opposite end can build Ipsec only by being configured as “always send certificate”. Send certificate under request: The local certificate is sent only when the opposite end sends a request. Not send certificate: The certificate will be send to the opposite end no matter the opposite end sends a request or not.	Always send certificate

3.7.2 GRE

Generic Route Encapsulation (GRE) defines the encapsulation of any other network layer protocol on a network layer protocol. GRE could be used as the L3TP of VPN to provide a transparent transmission channel for VPN data. In simple terms, GRE is a tunneling technology which provides a channel through which encapsulated data message could be transmitted and encapsulation and decapsulation could be realized at both ends. GRE tunnel application networking shown as the following figure:

Along with the extensive application of IPv4, to have messages from some network layer protocol transmitted on IPv4 network, those messages could by encapsulated by GRE to solve the transmission problems between different networks.

In following circumstances GRE tunnel transmission is applied:

GRE tunnel could transmit multicast data packets as if it were a true network interface. Single use of IPSec cannot achieve the encryption of multicast.
A certain protocol adopted cannot be routed.
A network of different IP address shall be required to connect other two similar networks.

GRE application example: combined with IPSec to protect multicast data

GRE can encapsulate and transmit multicast data in GRE tunnel, but IPSec, currently, could only carry out encryption protection against unicast data. In case of multicast data requiring to be transmitted in IPSec tunnel, a GRE tunnel could be established first for GRE encapsulation of multicast data and then IPSec encryption of encapsulated message so as to achieve the encryption transmission of multicast data in IPSec tunnel. As shown below:

From navigation tree, select VPN>>GRE Tunnels and enter "GRE Tunnels".

3.7.3 L2TP

L2TP, one of VPDN TPs, has expanded the applications of PPP, known as a very important VPN technology for remote dial-in user to access the network of enterprise headquarters.

L2TP, through dial-up network (PSTN/ISDN), based on negotiation of PPP, and could establish a tunnel between enterprise branches and enterprise headquarters so that remote user has access to the network of enterprise headquarters. PPPoE is applicable in L2TP. Through the connection of Ethernet and Internet, a L2TP tunnel between remote mobile officers and enterprise headquarters could be established.

L2TP-Layer 2 Tunnel Protocol encapsulates private data from user network at the head of L2 PPP. No encryption mechanism is available, thus IPSes is required to ensure safety.

Main Purpose: branches in other places and employees on a business trip could access to the network of enterprise headquarter through a virtual tunnel by public network remotely.

3.7.4 OPENVPN

Single point participating in the establishment of VPN is allowed to carry out ID verification by preset private key, third-party certificate or username/password. OpenSSL encryption library and SSLv3/TLSv1 protocol are massively used.

In OpenVpn, if a user needs to access to a remote virtual address (address family matching virtual network card), then OS will send the data packet (TUN mode) or data frame (TAP mode) to the visual network card through routing mechanism. Upon the reception, service program will receive and process those data and send them out through outer net by SOCKET, owing to which, the remote service program will receive those data and carry out processing, then send them to the virtual network card, then application software receive and accomplish a complete unidirectional transmission, vice versa.

3.8 Industrial (this Chapter Only Applies for IR900 Devices with Industrial Interface

Routers can connect with terminals through industrial interfaces, and can wirelessly upload data to upper devices. This realizes the wireless communication between terminals and upper devices.

Router’s industrial interface has two types: serial port and IO interface. Serial port has RS232 and RS485 modes and IO interface has digital input and relay output modes.

RS232 adopts full-duplex communication with one transmission line, one receiving line and one ground line. RS232 is generally used for communication within 20m.

RS485 adopts half-duplex communication to achieve long-distance transmission of serial communication data. To ensure the accuracy of long distance transmission for industrial sites, RS485 is normally used on industrial sites. RS485 is used for communication from tens of meters to kilometers.

Digital input of IO interface can convert electrical signals into binary digital control signals. The digital is a logical variable or switch variable with only two values 0 and 1. Low voltage corresponds to the “0” and high voltage to “1”

IO’s relay output functions as an “auto switch” to automatically adjust protect and switch circuit.
