 Modem over ISDN BRI for the Cisco 3640 Router 7

Verify

To verify the ISDN BRI interface configuration, use the commands demonstrated below. The text
shown in bold displays the results of configuration steps such as those shown in the “Configuration
Tasks” section on page 4.

Step 1

The show running-config command in EXEC mode shows the current configuration
running on the terminal. The example below shows some of the command output that is
relevant to B RI configuration tasks.

Note

The show startup-config shows the configuration stored in NVRAM or in a

location specified by the CONFIG_FILE environment variable.
