Viewing Information on Resource Usage

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-prioritycommand

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
