Configuring a Cisco 7200 VXR Router

Debugging

Cisco IOS provides two commands to provide information on your interfaces: show interface

GigabitEthernet 0/X (where X is 1, 2, or 3) and show controllers GigabitEthernet 0/1

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 I/O controller 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 on the NPE-G1 or NPE-G2

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

clear interface GigabitEthernet 0/X (where X is 1, 2, or 3.)

Clearing Counters on the NPE-G1 or NPE-G2

Interface counters on the NPE-G1 or NPE-G2 may be cleared (reset) by using the command:

clear counters GigabitEthernet 0/X (where X is 1, 2, or 3.)

This 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.

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

Number of bits in subnet field [0]:

Class C network is 1.1.1.0, 0 subnet bits; mask is /24
