show interface cable Command
To display cable interface information, use the show interface cable privileged EXEC command:
show interface cable slot/port [downstream | upstream]
See the following sample show interface cable command output for a cable modem located in
slot 1/port 0:
Router# show interface cable 1/0
Cable1/0 is up, line protocol is up
Hardware is BCM3210 FPGA, address is 00e0.1e5f.7a60 (bia 00e0.1e5f.7a60)

MTU 1500 bytes, BW 27000 Kbit, DLY 1000 usec, rely 255/255, load 1/255
Encapsulation, loopback not set, keepalive not set
ARP type: ARPA, ARP Timeout 04:00:00
Last input 4d07h, output 00:00:00, output hang never
Last clearing of “show interface” counters never
Queuing 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
10908 packets input, 855000 bytes, 0 no buffer
Received 3699 broadcasts, 0 runts, 0 giants, 0 throttles
3 input errors, 3 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
5412 packets output, 646488 bytes, 0 underruns
0 output errors, 0 collisions, 13082 interface resets
0 output buffer failures, 0 output buffers swapped out
Note The show interface upstream command is enhanced to display details on the MAC scheduler state for
an upstream port. Refer to the “Enhanced show interface upstream output Command” section on
page 5-27.
