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
Only one port adapter can be installed in the Cisco 7201 router. Following are three examples of three
different interfaces that might be used.
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:
Using your own addresses and mask at the setup prompts, respond to the prompts as follows:
Step 1
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
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]:
If you are using AppleTalk on the interface, enter yes. Enter yes to configure for extended AppleTalk
Step 3
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]:
