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.
Timesaver Before you begin, disconnect all WAN cables from the router to keep it from trying to run the AutoInstall
process. The router tries to run AutoInstall whenever you power it ON, if there is a WAN connection on
both ends and the router does not have a valid configuration file stored in nonvolatile random-access
memory (NVRAM) (for instance, when you add a new interface). It can take several minutes for the
router to determine that AutoInstall is not connected to a remote Transmission Control Protocol/Internet
Protocol (TCP/IP) host.
Before you begin configuring the BRI interface, make sure you:
• Connect a console to the router.
• Power on the router.
Step4
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)#.
Step5
Router(config-if)# ip address 172.16.74.1
255.255.255.0
Assign the IP address and subnet mask to the
interface.
Step6
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.
Step7
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.
Step8
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.
Step9
Router(config)# Ctrl-z
Router#
Return to enable mode.
