Cisco Systems PA-4R manual Using show Commands to Display Interface Information

Cisco 7200 Series and the 4R Port Adapter

Step 2 Display all the current interface processors and their interfaces with the show controllers command. Verify that the new 4R port adapter appears in the correct slot.

Step 3 Specify one of the new interfaces with the show interfaces port adapter type slot/interface 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-configcommand. Display the configuration stored in NVRAM using the show startup-configcommand. 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.

Using show Commands to Display Interface Information

To display information about a specific interface, use the show interfaces command with the interface type and port address in the format show interfaces [type slot/port].

Following is an example of how the show interfaces [type slot/port] command displays status information (including the physical slot and port address) for the interfaces you specify. In these examples, most of the status information for each interface is omitted, and the four Token Ring interfaces (0–3) are in port adapter slot 6. (Interfaces are administratively shut down until you enable them.)
