Reset 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 0, 1, 2, or 3)
Clear Counters
Interface counters may be cleared (reset) by using the command:
clear counters GigabitEthernet 0/X (where X is 0, 1, 2, or 3)
Note Using this command will not reset the interface.
Configure 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 Only one port adapter can be installed in the Cisco 7201 router. Following are three examples of three different
interfaces that might be used.
Configure 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:
I 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
Step 2 Determine if you are going to enable IPX on this interface; if you are, enter the unique IPX network number:
Configure IPX on this interface? [no]: yes
IPX network number [2]:
Step 3 If you are using AppleTalk on the interface, enter yes. Enter yes to configure for extended AppleTalk networks, and
then enter the cable range number. Enter the zone name and any other additional zones that are associated with your
local zone:
Configure AppleTalk on this interface? [no]: yes
Extended AppleTalk network? [no]: yes
AppleTalk starting cable range [0]:
Step 4 Save your settings to NVRAM. (See the “Check the Running Configuration Settings” section on page 40, and then the
“Save the Running Configuration to NVRAM” section on page 40.) If you do not save the configuration settings that
you created in the router using configuration mode and the setup facility, your configuration will be lost the next time
you reload the router.
