Depending on the complexity of your configuration, the Cisco 10000 series router supports up to 4,096
policy maps. In complex configurations the maximum number of policy maps can be as small as a few
hundred. Additionally, when you use percent-based policing in a service policy, the system may convert
a single customer-configured service to multiple service policies (which count against the 4096 limit).
The system uses one such service policy for each different speed interface that uses a service policy with
percent-based policing
Each policy-map command counts as one policy map and applying the same policy map on different
speed interfaces also counts as an extra policy map. The policy-map command syntax is unchanged.
Restrictions and Limitations for Per User Multiservice Rate Limiting
Do not apply service policies with CBWFQ actions to a VAI using a virtual template. The Cisco 10000
series router supports queuing only when you apply the service policy to a VC.
Per Session Service Policy Using RADIUS
The per session service policy using RADIUS feature enables a subscriber management server (SMS),
typically a RADIUS server, to dynamically change the traffic policing parameters for a user session.
The RADIUS server maintains user profiles to define subscriber parameters. The per session rate
limiting parameter is defined in the RADIUS authentication, authorization, and accounting (AAA) user
profiles. When a user logs into the network, the Cisco 10000 series router sends an authorization request
to the RADIUS server. If the user is a registered user, RADIUS sends the user profile to the router. The
user profile might include a per session service policy. If parameter values in the user profile change,
RADIUS sends the changed parameters when the user logs in to the system again.
