Verifying the Interface Configuration
Besides using the show running-configuration command to display the configuration settings of your Cisco
ASR 1000 Series Routers, use the show interfaces serial command and the show controllers serial command
to get detailed information on a per-port basis for your 2-Port and 4-Port T3/E3 Serial SPA.
Verifying the Per-Port Interface Status
To find detailed interface information on a per-port basis for the 2-Port and 4-Port T3/E3 Serial SPA, use the
show interfaces serial command.
The following example provides sample output for interface port 1 on the SPA located in the first subslot of
the SIP installed in slot 2 of a Cisco ASR 1000 Series Routers:
