Verifying the Interface Configuration
Saving the Configuration
To save your running configuration to nonvolatile random-access memory (NVRAM), use the following
command in privileged EXEC configuration mode:
For more information about managing configuration files, refer to the Cisco IOS Configuration
Fundamentals Configuration Guide, Release 12.2 and Cisco IOS Configuration Fundamentals
Command Reference, Release 12.2 publications.
Verifying the Interface Configuration
Besides using the show running-configuration command to display your Cisco 7304 router
configuration settings, you can use the show interfaces serial and the show controllers serial
commands to get detailed information on a per-port basis for your 2-Port or 4-Port T3/E3 SPA.
Verifying Per-Port Interface Status
To find detailed interface information on a per-port basis for the 2-Port or 4-Port T3/E3 SPA, use the
show interfaces serial command. For a description of the command output, see Chapter 18, “Command
Reference.”
The following example provides sample output for interface port 1 on the SPA located in the first subslot
of the SIP installed in slot 5 of a Cisco 7304 router:
