Addendum
The following sample output displays the CAM space utilization when Layer 2 and Layer 3 ACLs are
configured:

Allocating FP Blocks for VLAN Processes
This functionality is supported on the S4810, S4820T, Z9000, I/O Aggregator, and MXL platforms.
The VLAN ContentAware Processor (VCAP) application is a pre-ingress CAP that modifies the VLAN
settings before packets are forwarded. To support the ACL CAM optimization functionality, the CAM
carving feature is enhanced. A total of four VACP groups are present, of which two are for fixed groups
and the other two are for dynamic groups. Out of the total of two dynamic groups, you can allocate zero,
one, or two FP blocks to iSCSI Counters, OpenFlow and ACL Optimization.
You can configure only two of these features at a point in time.
• To allocate the number of FP blocks for VLAN open flow operations, use the cam-acl-vlan
vlanopenflow <0-2>
command.
