The ipv6acl and vman-dual-qos allocations must be entered as a factor of 2 (2, 4, 6, 8, 10). All other profile allocations can use
either even or odd numbered ranges.
You must save the new CAM settings to the startup-config (write-mem or copy run start) then reload the system for the new
settings to take effect.
1. Select a cam-acl action.
CONFIGURATION mode
cam-acl [default | l2acl]
NOTE:
Selecting default resets the CAM entries to the default settings. Select l2acl to allocate space for the ACLs
and QoS regions.
2. Enter the number of FP blocks for each region.
EXEC Privilege mode
l2acl number ipv4acl number ipv6acl number, ipv4qos number l2qos number, l2pt number ipmacacl
number ecfmacl number [vman-qos | vman-dual-qos number
NOTE:
If the allocation values are not entered for the CAM regions, the value is 0.
3. Verify that the new settings will be written to the CAM on the next boot.
EXEC Privilege mode
show cam-acl
4. Reload the system.
EXEC Privilege mode
reload
Test CAM Usage
To determine whether sufficient CAM space is available to enable a service-policy, use the test-cam-usage command. To verify the
actual CAM space required, create a Class Map with all required ACL rules, then execute the test cam-usage command in Privilege
mode. The Status column in the command output indicates whether or not you can enable the policy.
Example of the test cam-usage Command

View the current cam-acl settings using the show cam-acl command.
