MQC Support for IP Sessions

MQC Support for IP Sessions
The Modular QoS CLI (MQC) Support for IP Sessions feature extends the router's QoS functionality to
support per-user QoS on IP sessions. Using this feature, you can configure queuing and non-queuing
features on IP sessions, either locally on the router or remotely using a authentication, authorization, and
accounting (AAA) server such as RADIUS. This feature also supports dynamic interface association
(interface redundancy) for IP sessions, L2TP Network Server (LNS) sessions, and L2TP Access
Concentrator (LAC) sessions.
IP sessions provide a way to create subscriber sessions for hosts and subscribers based on an IP source
address or subnet. MQC for IP sessions supports the following session categories:
•
•
•
MQC for IP sessions supports policing on an IP session, whether the policing action is configured on
one or more traffic classes of the session or directly on the session. For example, you can configure
shaping on an IP session and configure policing on one or more traffic classes of the IP session. You can
also configure policing statically on an IP session.
MQC for IP sessions supports the dynamic configuration of IP sessions using a RADIUS user or service
profile. The router applies the incoming dynamic policy to the IP session if no policy map exists on the
IP session or the existing policy map is configured from a lower priority source.
Note
The router ignores the incoming dynamic policy if a policy map exists on the IP session and it is
configured from a higher priority source.

IP single-host session—An IP session that represents a single host. This session is based on an IP
source address.
IP subnet session—An IP session that represents a set of end users. This session is based on an IP
subnet.
IP interface session—A single session that is created for one subscriber interface. The router applies
all MQC features attached to the interface to all traffic arriving and leaving through that interface.
The router removes the existing, lower-priority sourced policy map before adding the incoming
dynamic policy.
