Monitoring Resources

Viewing Information on Resource Usage

Displaying Current Resource Usage

To display current resource usage in the switch, enter the show <qos access- list policy> resources command.

The show resources command output allows you to view current resource usage and, if necessary, prioritize and reconfigure software features to free resources reserved for less important features.

The qos, access-list, and policy parameters display the same command output and provide different ways to access task-specific information.

Syntax: show <qos access-list policy> resources

Displays the resource usage of the Policy Enforcement Engine on the switch by software feature. For each type of resource, the amount still available and the amount used by each software feature is shown.

Figure E1 shows the resource usage on a 3500yl switch configured for ACLs, QoS, RADIUS-based authentication, and other features:

The “Rules Used” columns show that ACLs, virus-throttling (VT), mirror­ ing, and other features (for example, Management VLAN) have been configured globally or per-VLAN because identical resource consumption is displayed for each port range in the switch. If ACLs were configured per-port, the number of rules used in each port range would be different.

The switch is also configured for virus throttling, and is either blocking or throttling routed traffic with a high rate of connection requests.

Varying ICMP rate-limiting configurations on ports 1-24, on ports 25-48, and on slot A, have resulted in different meter usage and different rule usage listed under QoS. Global QoS settings would otherwise result in identical resource consumption on each port range in the switch.

There is authenticated client usage of IDM resources on ports 25-48.
