Nonqueuing MQC over ATM

When a sessions that does not have a policy map starts, it inherits the policy and queues from the

immediate parent that has a policy (for example, a subinterface or main interface).

When a session with an inherited policy receives a policy from the RADIUS server, it first removes

the inherited policy and then applies the policy from the RADIUS server.

When a session without a policy starts and its parent interfaces also do not have a policy, but a policy

is later attached to the parent, one of the following actions occurs:

The policy is attached to the main interface and sessions directly on that interface inherit it.

Sessions on subinterfaces under the main interface that do not have a policy of their own also

The policy is attached to the subinterface and sessions under that subinterface inherit it.
