Policy Enforcement Engine

The Policy Enforcement engine is the hardware element in the switch that
manages quality-of-service, as well as other software features, using the rules
that you configure. Resource usage in the Policy Enforcement engine is based
on how these features are configured on the switch.
Resource usage by virus-throttling is determined as follows:
■

clients. When the throttling action ceases or a blocked client is unblocked,
the resources used for that action are released.

• QoS device priority (IP Address) through the CLI using the qos
device-priority command
Management VLAN configuration
Jumbo IP-MTU
QoS applied per-port or per-user through RADIUS authentication
