Feature History for MQC Support for IP Sessions
QoS Actions Supported in IP Session Policy Maps
Table 18-4 describes the QoS actions supported in inbound and outbound policy maps for IP sessions.
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.
