Understanding show Command Responses
show interface cable To display cable interface information, use the show interface cable command
in privileged EXEC mode:
show interface cable slot/port [downstream | upstream]
The following example displays show interface cable command output for a
CM located in slot1/port 0:
Router# show interface cable 5/0
Cable5/0 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
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
The show interface cable upstream command is enhanced to display details
on the MAC scheduler state for an upstream port.
New items in the display include:
• Detailed slot queue statistics—Queue [CIR Grants] 0/20, fair queuing, 0
drops in the previous example, meaning that the queue for CIR-service
grants has a current depth of 0, and a maximum depth of 20. Weighted fair
queuing shows grants in this queue.
• Constant bit rate (CBR) slot scheduling table state—The reserved slot table
in the previous example has two CBR entries. This shows that at the time
the command was issued, the MAC scheduler had admitted two CBR slots
in the reserved slot table.
• Counters for each type of upstream slot scheduled in the MAPs for this
upstream channel—The “Init Mtn IEs 800” means that the MAC scheduler
has added 800 initial maintenance information elements (slots) at the time
the show command was issued.
• MAC scheduling statistics—Displays the percentage of the upstream
bandwidth that is used for each type of slot on an average.
