Administrator Guide

NOTE: There can be only one odd number of Blocks in the CLI conguration; the other Blocks must be in factors of 2. For
example, a CLI conguration of 5+4+2+1+1 Blocks is not supported; a conguration of 6+4+2+1 Blocks is supported.
You must save the new CAM settings to the startup-cong (write-mem or copy run start) then reload the system for the new
settings to take eect.
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 nlbcluster number[vman-qos | vman-dual-qos number
3 Reload the system.
EXEC Privilege mode
reload
4 Verify that the new settings will be written to the CAM on the next boot.
EXEC Privilege mode
show cam-acl
Test CAM Usage
This command applies to both IPv4 CAM proles, but is best used when verifying QoS optimization for IPv6 ACLs.
Use this command to determine whether sucient 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.
Example of the test cam-usage Command
Dell#test cam-usage service-policy input pmap stack-unit all
Stack-Unit | Portpipe | CAM Partition | Available CAM | Estimated CAM per Port | Status
------------------------------------------------------------------------------------------
2 | 0 | L2ACL | 28 | 1 | Allowed (28)
View CAM-ACL Settings
