Using show Commands to Display Interface and System Information
The following example of the show interfaces type slot/port command shows all of the information specific to the serial E3 port (interface port 0) in port adapter slot 2:
router# show interfaces serial 2/0
Serial2/0 is up, line protocol is up Hardware is
Internet address is 172.16.0.0/8
MTU 4470 bytes, BW 34010 Kbit, DLY 200 usec, rely 255/255, load 1/255 Encapsulation HDLC, loopback not set, keepalive not set
Last input 00:00:05, output 00:00:46, output hang never Last clearing of "show interface" counters never Queueing strategy: fifo
Output queue 0/40, 0 drops; input queue 0/75, 0 drops 5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
22 packets input, 7128 bytes, 0 no buffer Received 22 broadcasts, 0 runts, 0 giants
0 parity
6 input errors, 3 CRC, 0 frame, 0 overrun, 0 ignored, 3 abort 22 packets output, 7348 bytes, 0 underruns
0 output errors, 0 applique, 6 interface resets
0 output buffer failures, 0 output buffers swapped out

For a VIP2, the show interfaces type
router# show interfaces serial 1/0/0 Serial1/0/0 is up, line protocol is up
Hardware is cyBus Serial Internet address is 10.0.0.0/24
MTU 4470 bytes, BW 45045 Kbit, DLY 200 usec, rely 255/255, load 1/255 Encapsulation HDLC, loopback not set, keepalive not set

For a Catalyst RSM/VIP2, the show interfaces
router# show interfaces serial 0/0 Serial0/0 is up, line protocol is up
Hardware is cyBus Serial Internet address is 10.0.0.0/24
MTU 4470 bytes, BW 45045 Kbit, DLY 200 usec, rely 255/255, load 1/255 Encapsulation HDLC, loopback not set, keepalive not set
Last input 2d22h, output 00:00:19, output hang never Last clearing of “show interface” counters 2d20h Queueing strategy: fifo
