Configuring Cable Profiles
Setting QoS Permission
The Cisco uBR7200 series router supports the creation of QoS table entries by SNMP or by cable modem registration requests. You can also configure the Cisco uBR7200 series to dynamically update QoS table entries via SNMP.
To set QoS table access, use one or more of the following commands in global configuration mode:
| Command | Purpose |
Step 1 |
|
|
CMTS01(config)# cable qos permission | Enables SNMP access to create entries in the QoS | |
|
| tables. |
Step 2 |
|
|
CMTS01(config)# cable qos permission | Enables SNMP access to dynamically update entries | |
|
| in the QoS tables. |
Step 3 |
|
|
CMTS01(config)# cable qos permission modems | Enables QoS table entries to be created via cable | |
|
| modem registration requests. |
Step 4 |
|
|
CMTS01(config)# no cable qos permission | Disables both SNMP access and cable modem | |
|
| registration access to the QoS tables. |
|
|
|
Verifying QoS Permission
To verify QoS permissions, enter the show cable qos permission command:
CMTS01# show cable qos permission
Create by SNMP | Update by SNMP | Create by modems |
no | no | yes |
Troubleshooting Tips
To troubleshoot the configuration, perform the following tasks:
•Make sure you are in global configuration mode.
•Make sure you typed the correct QoS profile number and profile elements.
•QoS profiles may be changed dynamically, permitting service tiers that are
Enforcing a QoS Profile Assignment
To override the provisioned QoS profile of the cable modems connecting to the Cisco uBR7200 series and enforce a
Command | Purpose |
|
|
CMTS01(config)# cable qos permission enforce index | Assigns the QoS profile, specified by the index number, to all |
| cable modems attempting to connect to the Cisco uBR7200 |
| series. |
