Viewing Information on Resource Usage
The switch allows you to view information about the current usage and
availability of resources in the Policy Enforcement engine, including the
following software features:
■ QoS through RADIUS authentication designated as “IDM”, with or without
the optional identity-driven management (IDM) application
■ Virus throttling (VT) using connection-rate filtering
■ Mirror policies. Other features, including:
• Management VLAN
• DHCP snooping
• Dynamic ARP protection
•Jumbo IP-MTU
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:
■ A virus-throttling configuration (connection-rate filtering) on the switch
does not affect switch resources unless traffic behavior has triggered
either a throttling or blocking action on the traffic from one or more
clients. When the throttling action ceases or a blocked client is unblocked,
the resources used for that action are released.
Resource usage by the following features (when configured globally or per
VLAN), applies across all port groups (or slots with installed modules):
■ QoS configurations that use the following commands:
• QoS device priority (IP Address) through the CLI using the qos
device-priority command
■ Management VLAN configuration
■ Jumbo IP-MTU
Resource usage on the following features, which are configured per-port,
applies only to the slot or port group on which the feature is configured:
■ QoS applied per-port or per-user through RADIUS authentication
■ QoS policies per port through the CLI using service
