The following sample output displays the CAM space utilization when Layer 2 and Layer 3 ACLs are congured:

Allocating FP Blocks for VLAN Processes
The VLAN ContentAware Processor (VCAP) application is a preingress CAP that modies 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 xed 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 congure only two of these features at a time.
• To allocate the number of FP blocks for VLAN open ow operations, use the cam-acl-vlan vlanopenflow <0-2>
command.
• To allocate the number of FP blocks for VLAN iSCSI counters, use the cam-acl-vlan vlaniscsi <0-2> command.
• To allocate the number of FP blocks for ACL VLAN optimization feature, use the cam-acl-vlan vlanaclopt <0-2>
command.
To reset the number of FP blocks to the default, use the no version of these commands. By default, zero groups are allocated for the
ACL in VCAP. ACL VLAN groups or CAM optimization is not enabled by default, and you need to allocate the slices for CAM
optimization.
