Configuring ISDN BRI WAN Interface Cards
Configuring ISDN BRI WAN Interface Cards
You can configure the interfaces on your BRI WAN interface card manually by entering Cisco IOS
commands on the command line. This method, called configuration mode, provides the greatest power
and flexibility.
Command
Purpose
Step 1
Router> enable
Password: password
Router#
Enter enable mode. Enter the password.
You have entered enable mode when the prompt
changes to
Router#
.
Step 2
Router# configure terminal
Enter configuration commands, one per line.
End with CNTL/Z.
Router(config)#
Enter global configuration mode. You have
entered global configuration mode when the
prompt changes to
Router(config)#.
Step 3
Router# ip routing
Router# appletalk routing
Router# ipx routing
Enable routing protocols as required for your
global configuration. This example uses IP
routing, AppleTalk routing, and Internetwork
Packet Exchange (IPX) routing.
Step 4
Router(config)# interface async 45
Router(config-if)#
Enter the interface configuration mode and specify
the asynchronous interface to configure. You have
entered interface configuration mode when the
prompt changes to
Router(config-if)#.
Step 5
Router(config-if)# ip address 172.16.74.1
255.255.255.0
Assign the IP address and subnet mask to the
interface.
Step 6
Router(config-if)# appletalk static
cable-range 5-5
Router(config-if)# appletalk zone ZZAsync
Router(config-if)# ipx network B003
Configure routing protocols on the interface. You
must have previously enabled these protocols as
part of global configuration. In this example,
AppleTalk and IPX are being configured on the
interface.
Step 7
Router(config-if)# async mode dedicated
Router(config-if)# async default routing
Router(config-if)# line async 45
Router(config-if)# speed 115200
Configure asynchronous parameters according to
your needs.
Step 8
Router(config-if)# exit
Return to the global configuration mode and
repeat Step 4 through Step 7 if your router has
more than one interface that you need to
configure.
Step 9
Router(config)# Ctrl-z
Router#
Return to enable mode.
