Verifying Interface Configuration

Note For CE1 ISDN PRI—If you do not specify the time slots, the specified controller is configured for 30 B channels and 1 D channel. B channel numbers range from 1 to 31; channel 16 is the D channel for E1. Corresponding serial interface numbers range from 0 to 30. In commands, the D channel is interface serial slot/port:15—for example, interface serial 1/0:15.

Step 6 Return to privileged EXEC mode:

Gateway(config-controller)# Ctrl-Z

Gateway#

Tip To save the gateway configuration, save it to NVRAM. See the “Saving Configuration Changes” section on page 60.

To verify that you have configured the interfaces correctly, enter these commands:

•Enter the show controller t3 command and specify the slot and port numbers. Verify that the controller is up and that you do not have excessive errors; otherwise, your controller might go down frequently. This could indicate switch problems.

Gateway# show controller t3 1/0

T3 1/0 is up.

Applique type is Channelized T3 No alarms detected.
