Using Other Related Commands
The following related Cisco IOS commands can be used to do maintenance on or display information about
a cable modem.
•
The following clears the counters for a cable modem (or all cable modems) in the station maintenance
list:
clear cable modem {mac-addr | ip-addr | all} counters
•
The following displays the QoS, modem status, In and Out octets, IP and MAC addresses per SID:
show int cable slot/port sid
• The following drops the modem’s RF link by removing a modem from the keepalive polling list. This
forces the modem to reset. Note the warning below.
clear cable-modem {mac-addr | ip-addr | all} reset
The clear cable-modem all reset command causes all modems to go offline and disrupt service for your
users. It is best used in a test or nonproduction environment.
Tip
•
The following uses a MAC-layer ping to determine if the cable modem is online. It uses smaller data
units on the wire than a standard IP ping, resulting in lower overhead. This command works even if the
IP layer in the modem is down or has not completed registration:
ping DOCSIS cable-modem mac-addr | IP address
•
The following displays the timing offset, receive power, and QoS values by cable interface, SID, and
MAC address:
show cable modem [ip-address | MAC-address]
•
The following displays the current allocation table and frequency assignments:
show cable spectrum-group [spectrum group number]
•
The following displays maximum, average, and minimum percent of online time and offline time for a
given SID on a given cable router interface:
show int slot/port sid connectivity
