2. Verify the new settings that will be written to CAM on the next reload. The CAM ACL ingress profiles are configured globally on the
PE. The show cam-acl-pe command does not display CAM ACL ingress profiles for each PE. The new settings will be written to
CAM on the next reload
EXEC and EXEC Privilege mode
show cam-acl-pe
3. Reload the system.

The following example displays the current CAM ACL settings for each ingress region and configures the ingress CAM settings.

Allocating CAM for Egress ACLs on the Port Extender
To allocate Content Addressable Memory (CAM) for egress ACLs on the port extender.
You can re-allocate memory space for egress ACLs on the port extender by using the cam-acl-egress-pe command in
CONFIGURATION mode.
The default CAM allocation settings for the three egress ACL and QoS regions on an switch are
• L2 ACL(l2acl): 1
• L3 ACL (ipv4acl): 1
• IPv6 L3 ACL (ipv6acl): 2
The total egress CAM ACL space must equal 4 memory blocks. The ranges of supported FP memory blocks are: You must allocate at least
one block of memory to the L2ACL and IPv4 ACL regions.
• L2 ACL(l2acl): 1 to 3
• L3 ACL (ipv4acl): 0 to 2
• IPv6 L3 ACL (ipv6acl): 0 to 4
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. Enter a CAM allocation action to perform on egress ACLs. Enter the number of FP blocks for each region. Separate each keyword and
number with a blank space. The total CAM space allocated must equal 12.
CONFIGURATION mode
cam-acl-pe [default| l2acl number ipv4acl number ipv6acl number ipv4qos number l2qos number
ipmacacl number ipv4pbr number]
NOTE:
Selecting default resets the CAM entries to the default settings. Select l2acl to re-allocate memory space
for egress ACL and QoS regions
2. Verify the details of CAM ACL egress profiles configured globally on the PE. It does not display CAM ACL egress profiles for each PE.
The new settings will be written to CAM on the next reload.
