Cisco Systems PA-E3, PA-2E3 manual Number, Checking the Configuration Step

Checking the Configuration

Step 4	Specify one of the new interfaces as follows:
	• show interfaces port adapter type slot/port on Cisco 7100 series, Cisco 7200 series,
	and Cisco uBR7200 series routers
	• show interfaces type slot/port adapter/interface command on the VIP2
	• show interfaces port adapter/interface command on the Catalyst RSM/VIP2
	Verify that the first line of the display specifies the interface with the correct slot number
	and that the interface and line protocol are in the correct state: up or down.
Step 5	View the information that is specific to the serial interface hardware:
	• For Cisco 7100, Cisco 7200 series and Cisco uBR7200 series routers, specify the new
	serial interface with the show controllers serial [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.
	• For a VIP2, specify information that is specific to the new serial interface with the
	show controllers serial [type slot/port adapter/interface] command, and verify that
	the first line of the display specifies the interface with the correct slot number.
	• For a Catalyst RSM/VIP2, specify information that is specific to the new serial
	interface with the show controllers serial [port adapter/interface] command, and
	verify that the first line of the display specifies the interface with the correct slot
	number.
Step 6	Display the protocols configured for the entire system and for the specific interfaces with
	the show protocols command. If necessary, return to configuration mode to add or
	remove protocol routing on the system or on specific interfaces.
Step 7	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, ask a service representative for assistance.

Using show Commands to Display Interface and System Information

For Cisco 7100, Cisco 7200, or Cisco uBR7200 series routers, 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.
