Table 13. Additional Default CAM Allocation Settings
Additional CAM Allocation Setting
FCoE ACL (fcoeacl) 0
ISCSI Opt ACL (iscsioptacl) 0
You must enter the ipv6acl and vman-dual-qos allocations as a factor of 2 (2, 4, 6, 8, 10). All other profile allocations can use either
even or odd numbered ranges.
NOTE: You can only have one odd number of blocks in the CLI configuration; the other blocks must be in factors of 2.
For example, a CLI configuration of 5+4+2+1+1 blocks is not supported; a configuration of 6+4+2+1 blocks is supported.
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

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 ecfmacl number nlbcluster number
ipv4pbr number openflow number | fcoe number iscsioptacl number [vrfv4acl number] [radius-
v4acl 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.
