Interface Support for MQC on IP Sessions
The router supports the following interfaces for MQC on IP sessions:
•
Physical Ethernet
•
IEEE 802.1Q VLAN
•
QinQ (only unambiguous)
•
Nonqueuing MQC over ATM
Policies and Queues Inheritance Rules
The following inheritance rules apply to policies and queues from the parent interface:
•
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
inherit it.
–
The policy is attached to the subinterface and sessions under that subinterface inherit it.
