Displaying current resource usage
To display current resource usage in the switch, enter the following command:
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.
|
This output allows you to view current resource usage and, if necessary, prioritize and reconfigure software features to free resources reserved for less important features. |
|
Display the same command output and provide different ways to access task-specific information. See “Viewing OpenFlow Resources” in the OpenFlow administrators guide for your switch. |
Displaying current resource usage shows the resource usage on a switch configured for ACLs, QoS, RADIUS-based authentication, and other features:
The "Rules Used" columns show that ACLs, VT, mirroring, 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.

2 of 16 Policy Engine management resources used.
Key:
ACL = Access Control Lists
QoS = Device & Application Port Priority
IDM = Identity Driven Management
Other = Management VLAN, DHCP Snooping, ARP Protection, RA Guard.
Resource usage includes resources actually in use, or reserved for future
use by the listed feature. Internal dedicated-purpose resources, such as
port bandwidth limits or VLAN QoS priority, are not included.
