Checking the Configuration
For Cisco 7100, Cisco 7200, and Cisco uBR7200 series routers, use the show controllers serial
command, using arguments such as the slot and port number (slot/port), to display information that
is specific to the serial interface hardware. Following is an example of the show controllers serial
slot/port command that shows the serial port adapter installed on a Cisco 7200 series router in
chassis slot 3:
router# show controllers serial 3/0
M1T-Serial: show controller:
PAS unit 0, subunit 0, f/w version 1-23, rev ID 0x1, version 2
idb = 0x608E3340, ds = 0x608E50C0, ssb=0x608E5A84
Clock mux=0x35, ucmd_ctrl=0x8, port_status=0x25
maxdgram=4474, bufpool=64Kb, 128 particles

For a VIP2, use the show controllers serial command, using arguments such as those that specify
the slot, port adapter, and port numbers (slot/port-adapter/port), to display information that is
specific to the serial interface hardware. Following is an example of the show controllers serial
slot/port adapter/interface command that shows serial port 2/0/1 on a one-port PA-E3 installed on a
VIP2 in chassis slot 1:
router# show controllers serial 2/0/1
Serial2/0/1
