Fourth Generation Versatile Interface Processor (VIP4) Installation and Configuration Guide

OL-3673-01

Checking the VIP4 Installation

Using show Commands to Verify the VIP4 Status

The following steps use show commands to verify that the new interfaces are configured and operating

correctly.

Step 1 Use the show version command to display the system hardware configuration. Ensure that the list

includes the new interfaces.

Step 2 Display all the current interface processors and their interfaces with the show controllers command.

Verify that the new VIP4 appears in the correct interface processor slot.

Step 3 Specify one of the new interfaces with the show interfaces type interface-processor-slot-

number/port-adapter-slot-number/interface-port-number command and verify that the first line of the

display specifies the interface with the correct slot number. Also verify that the interface and line

protocol are in the correct state: up or down.

Step 4 Display the protocols configured for the entire system and specific interfaces with the show protocols

command. If necessary, return to configuration mode to add or remove protocol routing on the system

or specific interfaces.

Step 5 Display the running configuration file with the show running-config command. Display the

configuration stored in the RSP NVRAM using the show startup-config command. Verify that the

configuration is accurate for the system and each interface.

If the interface is down and you configured it as up, or if the displays indicate that the hardware is not

functioning properly, ensure that the network interface is properly connected and terminated. If you still

have problems bringing the interface up, contact a service representative for assistance.

Note The outputs that appear in this document may not match the output you receive when running these

commands. The outputs in this document are examples only.

Using show Commands to Display Interface Information

To display information about a specific interface, use the show interfaces command with the interface

type and interface address in the format show interfaces type interface-processor-slot-

number/port-adapter-slot-number/interface-port-number.

With the show interfaces command, use arguments such as the interface type and the interface address

to display information about a specific interface only. The following example of the

show interfaces fastethernet command shows information specific to a VIP4 with a Fast Ethernet port

adapter (PA-2FE) installed; the VIP4 is installed in interface processor slot 1:
