show interface cable
To display the current configuration and status of a cable interface, use the show interface cable
command in privileged EXEC mode.
show interface cable {slot/port | slot/subslot/port} [options]
Syntax Description slot/port Identifies the cable interface and downstream port on the
Cisco uBR7100 series and Cisco uBR7200 series routers.
On the Cisco uBR7100 series router, the only valid value is 1/0. On
the Cisco uBR7200 series router, slot can range from 3 to 6, and port
can be 0 or 1, depending on the cable interface.
slot/subslot/port Identifies the cable interface on the Cisco uBR10012 router. The
following are the valid values:
slot = 5 to 8
subslot = 0 or 1
port = 0 to 4 (depending on the cable interface)
