Show Interface Cable

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 6/port 0 using the earlier Cisco IOS Release 12.1(5)T1 software:

router# show interface cable 6/0 Cable6/0 is up, line protocol is up

Hardware is BCM3210 FPGA, address is 00e0.1e5f.7a60 (bia 00e0.1e5f.7a60) Internet address is 1.1.1.3/24

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 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

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 For more recent images such as Cisco IOS Release 12.1(1a)T1 or higher, the show interface upstream command is enhanced to display details on the MAC scheduler state for an upstream port. Refer to “Enhanced Show Interface Upstream Output” section on page 4-30.
