Chapter 3      Starting and Configuring

  Configuring a Cisco 7401ASR Router

Debugging 

Cisco IOS provides two commands to provide information on your interfaces: show interface 
GigabitEthernet 0/X (where X is either 0 or 1) and show controllers GigabitEthernet 0/X (where X 
is either 0 or 1). 

The output of the show interface command is useful for determining the current operating mode of the 
interface (speed/duplex/media-type) and the current interface statistics.

The output of the show controller command displays more information specific to the Cisco 7401ASR 
router Gigabit Ethernet interface. For example, it shows the detected link status, speed, and duplex, and 
also determines the current status of autonegotiation and the link partners’ abilities (if it is an 
autonegotiation-capable interface).

The show controller command also displays the current operating state of the driver and the Ethernet 
controller hardware. The show controller command is a very powerful debugging aid, especially for 
Cisco engineers should you need help in debugging a problem. If you have any problems with your 
Gigabit Ethernet interfaces, you will need to provide this information to Cisco for analysis.

Resetting the Interface

Should you have a problem with your interface and you want to try and reset it, use the command:

clear interface GigabitEthernet 0/X (where X is either 0 or 1)

Clearing Counters

Interface counters may be cleared (reset) by using the command:

clear counters GigabitEthernet 0/X (where X is either 0 or 1)

Note

Using this command will not reset the interface.

Configuring Port Adapter Interfaces 

Following are the steps for configuring interfaces to allow communication over a LAN or WAN. To 
configure the interface parameters, you need your interface network addresses and subnet mask 
information. Consult with your network administrator for this information.

Note

See 

Chapter 4, “Configuring the VPN Acceleration Module,”

 for instructions on configuring VAM.

Configuring ATM Interfaces

In the following example, an ATM interface in slot 1 is configured for an ATM LAN using IP. Follow 
these steps to configure an ATM interface:

Step 1

Using your own addresses and mask at the setup prompts, respond to the prompts as follows:

Configuring interface parameters:

Configuring interface ATM1/0:

  Is this interface in use? [yes]: 

  Configure IP on this interface? [yes]:

    IP address for this interface: 1.1.1.10
