Table 11. Default Cam Allocation Settings (continued)
CAM Allocation Setting
fedgovacl 0
nlbclusteracl 0
NOTE: When you reconfigure CAM allocation, use the nlbclusteracl number command to change the number of NLB ARP
entries. The range is from 0 to 2. The default value is 0. At the default value of 0, eight NLB ARP entries are available for
use. This platform supports upto 512 CAM entries. Select 1 to configure 256 entries. Select 2 to configure 1024 entries.
Even though you can perform CAM carving to allocate the maximum number of NLB entries, Dell EMC Networking
recommends you to use a maximum of 64 NLB ARP entries.
The following additional CAM allocation settings are supported.
Table 12. Additional Default CAM Allocation Settings
Additional CAM Allocation Setting
FCoE ACL (fcoeacl) 0
ISCSI Opt ACL (iscsioptacl) 0
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.
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

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.
