Reference Guide

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 512 entries. Even though you can perform
CAM carving to allocate the maximum number of NLB entries, Dell Networking recommends you to
use a maximum of 64 NLB ARP entries.
The following additional CAM allocation settings are supported.
Table 11. Additional Default CAM Allocation Settings
Additional CAM Allocation Setting
FCoE ACL (fcoeacl) 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.
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.
