Users 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 1024 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 12. 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.
