To configure ISDN BRI interfaces, perform the following steps:
Task Command
Step 1
Enter enable mode.
Enter the password.
You know you have entered enable mode when the prompt
changes to
gateway#.
gateway> enable
Password:
<password>
gateway#
Step 2
Enter global configuration mode.
You know you have entered global configuration mode
when the prompt changes to
gateway(config)#.
gateway# configure terminal
Enter configuration
commands, one per line. End
with Ctrl-Z.
gateway(config)#
Step 3
Enter an ISDN switch type. See Table 4-2 for a list of ISDN
switch types.
Note Switch types configured in interface
configuration mode override this setting for the
configured interface.
gateway(config)# isdn
switch-type switch-type
Step 4
Enable routing protocols as required for your global
configuration.
gateway(config)# ip routing
Step 5
Enter the interface configuration mode.
You know you have entered interface configuration mode
when the prompt changes to
gateway(config-if)#.
gateway(config)# interface
bri 2/0
gateway(config-if)#
Step 6
Enable encapsulation. For data, you need to change the
encapsulation to hdlc, ppp, or frame-relay. The default is
voice.
gateway(config)# encaps
encaps-type
Step 7
Assign the IP address and subnet mask to the interface.
If you are configuring this interface for voice, enter the
switch type instead of an IP address.
gateway(config-if)# ip
address 172.16.74.2
255.255.255.0
gateway(config-if)# isdn
switch-type basic-5ess
Step 8
Exit back to global configuration mode.
If your Catalyst 4224 has more than one BRI interface that
you need to configure, repeat Step 5 through Step 7.
gateway(config-if)# exit
