Administrator Guide

1. Enter a CAM allocation action to perform on ingress 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. When configuring space
foripv6acl, the total number of Blocks must be in multiples of 2.
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
ingress ACL and QoS regions.
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.
EXEC Privilege mode
reload
The following example displays the current CAM ACL settings for each ingress region and configures the ingress CAM settings.
Dell(conf)#do show cam-acl-pe

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.
