Setup Guide

You must enter l2acl, ipv4acl, l2qos, l2pt, ipv4qos, ipv4pbr, vrfv4acl, and fcoe allocations as a factor of 2, ipv6acl,
openflow, and vman_qos allocations as a factor of 3. Ipv4 acl region should also be in multiples of 3 when ipv4udf option is
enabled. All other profile allocations can use either even or odd numbered ranges.
For the new settings to take effect, 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.
CAM Allocation for Egress
To allocate the space for egress L2, IPV4, and IPV6 ACL, use the cam-acl-egress command. The total number of available FP blocks
is 4. Allocate at least one group of L2ACL and IPV4 ACL.
DellEMC(conf)#do show cam-acl-egress
-- Chassis Egress Cam ACL --
Current Settings(in block sizes)
1 block = 256 entries
L2Acl : 1
Ipv4Acl : 1
Ipv6Acl : 2
-- Stack unit 1 --

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 the desired space
for all other regions.
2. Enter the number of FP blocks for each region.
EXEC Privilege mode
cam-acl {default | l2acl number ipv4acl number ipv6acl number ipv4qos number l2qos number
l2pt number ipmacacl number vman-qos | vman-dual-qos number nlbcluster number ipv4pbr number
openflow number | fcoe number [vrfv4acl number]
NOTE:
If you do not enter the allocation values for the CAM regions, the value is 0.
3. Execute write memory and verify that the new settings are 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
To determine whether sufficient CAM space is available to enable a service-policy, use the test-cam-usage command. To verify the
actual CAM space required, create a Class Map with all required ACL rules, then execute the test cam-usage command in Privilege
mode. The Status column in the command output indicates whether or not you can enable the policy.
Example of the test cam-usage Command
DellEMC#test cam-usage service-policy input test-cam-usage stack-unit 1 po 0
