show controller bri
The interface hardware controller information is displayed with the show
controller bri
command. This command is most useful for troubleshooting
with Cisco's TAC, but some information can assist the administrator. Most
important, the status of the interface, in this case a U type connection, and the
superframe error counter are available in this show command.
