Applying QoS Parameters Dynamically to Sessions

Example 17-13 shows sample output for the show atm pvc command, which enables you to display
information about a particular PVC. As indicated in the example, the high watermark for PVC 1/100 is
set to 56 and the low watermark is set to 48. The weight is set to 12.

Applying QoS Parameters Dynamically to Sessions
The Define Interface Policy-Map AV Pairs AAA feature provides two Cisco vendor-specific attributes
(VSAs) that allow you to dynamically apply a policy map and modify a policy map applied to a session,
without session reauthentication, at the ATM VC level using RADIUS.
The two new Cisco VSAs are set up in the user file on the RADIUS server. These two AV pairs are
vc-qos-policy-in and vc-qos-policy-out, and are formatted as follows:
cisco-avpair = "atm:vc-qos-policy-in=<in policy name>"
cisco-avpair = "atm:vc-qos-policy-out=<out policy name>"
The Define Interface Policy-Map AV Pairs AAA feature allows the two new Cisco VSAs to be installed
on an ATM VC after a PPPoA or PPPoEoA session establishment. Using RADIUS, this feature allows
a policy map to be applied ("pulled") and then modified by specific events ("pushed" by the Policy
Server) while that session remains active.
