Policy Enforcement and Usage Monitoring
You can enforce dynamic QoS policies and upstream and downstream TCP or UDP data rates on 802.11 clients seamlessly without disrupting the client's ongoing sessions. The feature ensures that clients do not have to get dissociated from the network. All the authentication methods: 802.1X, PSK, web authentication, and so on, are supported.
The APs periodically send client statistics including bandwidth usage to the Controller. The AAA server receives Accounting-Interim messages which include the clients data utilization at the configured intervals. The AAA server accumulates information about data consumption for each client and when the client exhausts the data limit, the AAA server sends a change-of-authorization (CoA) message to the Controllers. Upon successful CoA handshakes, the Controllers apply and send new policies to the APs.
Restrictions on Policy Enforcement and Usage Monitoring
Only FlexConnect local switching mode is supported.
