Task 4: Configure IP on an Interface

Typically, you configure IP on the Fast Ethernet interface of the SRP module. To configure IP on an interface:

1. Determine the slot number of the module.

   host1#show version

2. Determine the port number of the module.
3. Determine whether the interface already has an IP address.
   • On ERX-7xx models, ERX-14xx models, and the ERX-310 router:

     host1#show ip interface fastEthernet 6/0
     

   • On the E120 router and the E320 router:

     host1#show ip interface fastEthernet 6/0/0

     Note: If an IP interface is not configured, an Invalid interface message appears.

   If the interface already has an IP address, go to Step 5. Otherwise, proceed with Step 4.

4. Configure an IP address on the interface.
   • On ERX-7xx models, ERX-14xx models, and the ERX-310 router:

     host1#configure

     Configuring from terminal or file [terminal]?

     Enter configuration commands, one per line. End with CNTL/Z.

     host1(config)#interface fastEthernet 6/0

     host1(config-if)#ip address ipAddress [ mask ]

   • On the E120 router and the E320 router:

     host1#configure

     Configuring from terminal or file [terminal]?

     Enter configuration commands, one per line. End with CNTL/Z.

     host1(config)#interface fastEthernet 6/0/0

     host1(config-if)#ip address ipAddress [ mask ]

5. Press Ctrl+z to return to Privileged Exec mode.
