Users Guide

The following additional CAM allocation settings are supported.
Table 11. 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 prole allocations can use either even or odd numbered ranges.
NOTE: You can only have one odd number of blocks in the CLI conguration; the other blocks must be in factors of 2. For
example, a CLI conguration of 5+4+2+1+1 blocks is not supported; a conguration of 6+4+2+1 blocks is supported.
For the new settings to take eect, you must save the new CAM settings to the startup-cong (write-mem or copy run start)
then reload the system for the new settings to take eect.
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.

: 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.
