Service Manual

• L2 ACL(l2acl): from 1 to 4

• L3 ACL (ipv4acl): from 1 to 4

• IPv6 L3 ACL (ipv6acl): from 0 to 4

You must allocate at least one block of memory to the L2ACL and IPv4 ACL regions.

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.

To reconfigure the memory regions on the S5000 used for egress ACLs and QoS, follow these steps.

1 Enter the number of FP blocks for each egress ACL region. Separate each keyword and number with a

blank space.

CONFIGURATION mode

cam-acl-egress l2acl number ipv4acl number ipv6acl number

The total CAM space allocated must equal four.

2 Verify the new settings that are written to CAM on the next reload.

EXEC Privilege mode

show cam-acl-egress

3 Reload the system.

EXEC Privilege mode

reload

Testing CAM Usage for QoS Policies

The test cam-usage command applies to the IPv4 ingress CAM partition.

To determine whether there is sufficient space in this CAM region for the ACLs created in QoS service-

policies, use this command.

You can create a class map with all required ACL rules and then enter the test cam-usage command in

Privilege mode to verify the actual CAM space required. The following example shows the command output.

The status column indicates whether you can enable the policy.

Example of the test cam-usage Command

Dell# test cam-usage service-policy input TestPolicy stack-unit all
