Troubleshooting Wideband Channels
This section describes troubleshooting techniques for wideband channels. It includes the following
sections:
•
Verifying That a Wideband Channel is Up and Is Transmitting Packets
•
Verifying That a Wideband Channel is Configured Correctly
For information on configuring wideband channels, see the
Cisco uBR10012 Universal Broadband
Router SIP and SPA Software Configuration Guide
.
Verifying That a Wideband Channel is Up and Is Transmitting Packets
To verify that a wideband channel is up and transmitting packets, use the
show interface
wideband-cable
command and examine the first line of output and the packets output field:
Router# show
interface wideband-cable 1/0/0:1
Wideband-Cable1/0/0:1 is up, line protocol is up
Hardware is Wideband CMTS Cable interface, address is 0012.001a.8897 (bia
0012.001a.8897)
MTU 1500 bytes, BW 74730 Kbit, DLY 1000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation MCNS, loopback not set
Keepalive set (10 sec)
ARP type: ARPA, ARP Timeout 04:00:00
Last input never, output 00:00:09, output hang never
Last clearing of "show interface" counters never
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: fifo
Output queue: 0/40 (size/max)
30 second input rate 0 bits/sec, 0 packets/sec
30 second output rate 0 bits/sec, 0 packets/sec
0 packets input, 0 bytes, 0 no buffer
Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
24224 packets output
, 1222002 bytes, 0 underruns
0 output errors, 0 collisions, 0 interface resets
0 output buffer failures, 0 output buffers swapped out
For information on what criteria are used to determine whether a wideband channel and its associated
line protocol are up, see the
“show interface wideband-cable” section on page 5-6
