Checking the Configuration

Using show Commands to Verify the New Interface 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	For the Cisco 7200 series and Cisco uBR7200 series routers, display all the current port
	adapters and their interfaces with the show controllers command. Verify that the new
	HSSI port adapter appears in the correct slot.
	For the VIP2, display all the current interface processors and their interfaces with the
	show controllers cbus command. Verify that the new VIP2 appears in the correct slot.
	Note The slot values displayed by some commands (such as show diag and show
	controllers cbus) are not relevant to any physical connection; disregard these slot values
	for the Catalyst RSM/VIP2.
Step 3	For the Cisco 7200 series and Cisco uBR7200 series routers, 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.
	Note For the Cisco 7206 and Cisco 7206VXR router shelves, the show interfaces
	command requires a shelf number in the format show interfaces type shelf number/port
	adapter slot/interface.
	For the VIP2, specify one of the new interfaces with the show interfaces type slot/port
	adapter/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.
	For the Catalyst RSM/VIP2, specify one of the new interfaces with the show interfaces
	port adapter/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-config command. Display
	the configuration stored in 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.
