Configuring CoS Variables in a Dynamic Profile

You can configure user-defined variables in the dynamic profile for traffic scheduling and shaping parameters.

Configuring RADIUS attributes as variables for CoS parameters enables subscribers to upgrade or downgrade services after login using a RADIUS change of authorization (CoA).

Alternatively, you can use variables to provide subscribers with default values for CoS parameters. If you have configured values to be supplied by a RADIUS CoA, subscribers can receive the previously configured default value when deactivating a service.

You activate the variables by referencing them in the traffic control profile configured in the dynamic profile.

To configure variables for CoS in a dynamic profile:

Specify that you want to configure variables in the dynamic profile.[edit variables]
Do one of the following to configure variables for the shaping rate:
- Enable RADIUS to modify the shaping rate based on service changes.
  1. Configure the attribute:[edit variables] user@host# set srate attribute 108
  2. Configure the tag:[edit variables] user@host# set srate tag 1
- Configure a default value for the shaping rate.[edit variables] user@host# set srate default-value 10m
Do one of the following to configure variables for the guaranteed rate.
- Enable RADIUS to modify the guaranteed rate based on service changes.
  1. Configure the attribute:[edit variables] user@host# set grate attribute 108
  2. Configure the tag:[edit variables] user@host# set grate tag 2
- Configure a default value for the guaranteed rate.[edit dynamic-profiles residential-silver variables] user@host# set grate default-value 5m
Do one of the following to configure variables for the delay buffer rate:
- Enable RADIUS to modify the delay buffer rate based on service changes.
  1. Configure the attribute:[edit variables] user@host# set dbrate attribute 108
  2. Configure the tag:[edit variables] user@host# set dbrate tag 3
- Configure a default value for the delay buffer rate.[edit dynamic-profiles residential-silver variables] user@host# set dbrate default-value 10m
Do one of the following to configure variables for the scheduler map.
- Enable RADIUS to modify the scheduler map based on service changes.
  1. Configure the attribute:[edit variables] user@host# set smap attribute 108
  2. Configure the tag:[edit variables] user@host# set smap tag 4
- Configure a default value for the scheduler map.[edit dynamic-profiles residential-silver variables] user@host# set smap default-value triple-play
Configure the variables for the CoS parameters in the traffic control profile.
Either the shaping rate or the guaranteed rate are required in the traffic control profile.
1. Specify that you want to configure CoS parameters in the dynamic profile.user@host# edit dynamic-profiles residential-silver class-of-service traffic-control-profiles tcp1
2. Configure the scheduler map variable.[edit dynamic-profiles residential-silver class-of-service traffic-control-profiles tcp1] user@host# set scheduler-map "$smap"
3. Configure the shaping rate variable.[edit dynamic-profiles residential-silver class-of-service traffic-control-profiles tcp1] user@host# set shaping-rate "$srate"
4. Configure the guaranteed rate variable.[edit dynamic-profiles residential-silver class-of-service traffic-control-profiles tcp1] user@host# set guaranteed-rate "$grate"
5. Configure the delay buffer rate variable.[edit dynamic-profiles residential-silver class-of-service traffic-control-profiles tcp1] user@host# set delay-buffer-rate "$dbrate"
