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 nlbclusteracl 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
The test cam-usage command applies to both IPv4 and IPv6 CAM profiles, but is best used when verifying QoS optimization
for IPv6 ACLs.
Use this command to determine whether sufficient ACL CAM space is available to enable a service-policy. Create a Class Map
with all required ACL rules, then execute the test cam-usage command in Privilege mode to verify the actual CAM space
required. The Status column in the command output indicates whether or not the policy can be enabled.
