Managing Cable Modems on the HFC Network

Verifying a QoS Profile Assignment

To verify a QoS profile assignment, perform the following steps:

Step 1 Load the Cisco uBR7200 series and wait for the cable modems to come online as indicated by the show cable modem command.

Notice that the modems are getting their provisioned class of service as indicated by the show cable modem and show cable qos profile commands.

Step 2 Configure any QoS profile at the CMTS with a specific index number (for example, index 1) by using the SNMP/CLI.

Step 3 Enter the cable qos permission enforce 1 global configuration command.

Step 4 Enter the clear cable modem all reset global configuration command to force the modems to reregister with the CMTS.

Notice that the cable modems are assigned temporarily the CMTS-defined PRE_REGISTRATION QoS profile with index 2 until the cable modems register with the CMTS.

Step 5 Use the debug cable reg command to see that the provisioned QoS parameters of the modems are overwritten at the CMTS during registration.

Notice that at the end of the registration, the modem gets the user-enforced QoS profile as indicated by the show cable modem and show cable qos profile commands.

For additional information, refer to the cable qos permission enforce command reference page in the Cisco IOS Multiservice Applications Command Reference.
