Command History
Usage Guidelines
This command activates dynamic service flow debugging, which displays a debugging message
whenever one of the following DOCSIS 1.1 dynamic service messages is processed:
•
Dynamic Service Add (DSA)—This message is used to create a new service flow.
•
Dynamic Service Change (DSC)—This message is used to change the attributes of an existing
service flow.
•
Dynamic Service Deletion (DSD)—This message is used to delete an existing service flow.
Each type of dynamic service message includes a request (DSA-REQ, DSC-REQ, DSD-REQ) and a
response (DSA-RSP, DSC-RSP, DSD-RSP).
Do not use this command when you have a large number of active CMs on your network, because it could
generate a huge amount of output to the console port.
Note
Debugging must be enabled for one or more cable interfaces, using the
debug cable interface
command,
before the
debug cable dynsrv
command will display any output.
Tip
If using the
debug cable dynsrv
command, also use the
debug cable mac-address
and the
debug cable
tlvs
command to enable full DOCSIS MAC-layer debugging.
Examples
The following example shows typical output displayed by the
debug cable dynsrv
command:
