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:
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 time-sensitive (more
bandwidth during business hours than on weekends).
Enforcing a QoS Profile Assignment
To override the provisioned QoS profile of the cable modems connecting to the Cisco uBR7200 series
and enforce a CMTS-specified QoS profile, use the following command in global configuration mode:
Command Purpose
Step 1
CMTS01(config)# cable qos permission create-snmp
Enables SNMP access to create entries in the QoS
tables.
Step 2
CMTS01(config)# cable qos permission update-snmp
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.
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.
