3Com 3015 (3C13615), 3013 (3C13613), 3018 (3C13618) manual Configure the WAN port of the router

Configuration Fundamentals of the Router 35

3Configure the WAN port of the router:

■Configure the physical operating parameters (the operating mode of the serial port, baud rate, and synchronous clock) of the port according to the transmission medium of the WAN. For the dial-up port, you need to configure DDR parameters.

■Configure the link layer protocol encapsulated on the port and the related operating parameters according to the type of the WAN.

4Configure the IP addresses or IPX network number for all the ports of the router according to the division of the subnets.

5Configure the routes. If you have to start up the dynamic routing protocol, configure the related operating parameters of the protocol.

6Create the security configuration for the router, as necessary.

7Create the reliability configuration for the router, as necessary.

SNMP Management For help managing routers on your network, you can use 3Com Network Supervisor software to discover, map, and display network links and IP devices.

To allow Network Supervisor to monitor your routers, you must first configure

SNMP V1 and SNMP Trap support with the following commands:

[3Com]snmp-agent sys-info version v1

[3Com]snmp-agent community read <read-community-string>

[3Com]snmp-agent community write <write-community-string>

[3Com]snmp-agent trap enable

[3Com]snmp-agent target-host trap address <addr> parameter v1 securityname <security-name-string>

In this example, <addr> is the address of the PC on which you have installed Network

Supervisor.

Command Line Interface The command line interface of the Router 3000 series routers provides commands to configure and manage the router. The command line interface has the following characteristics:

■Performs the local configuration through the console port.

■Performs local or remote configuration through the telnet command, which can be used to log on directly and manage other routers.

■Implements the configuration on the router through the terminals (the asynchronous port, including those connected to the AUX port and AS port) in the dumb terminal mode.

■Configures the hierarchical user protection (guest, operator, administrator). Only administrator users are authorized to configure and manage the routers.

■Online help, available by typing ? at any time.
