Allocating FP Blocks for VLAN Processes

The VLAN contentaware processor (VCAP) application is a pre-ingress CAP that modifies the VLAN settings before packets are
forwarded. To support ACL CAM optimization, the CAM carving feature is enhanced. A total of four VCAP groups are present: two
fixed groups and two dynamic groups. Of the two dynamic groups, you can allocate zero, one, or two FP blocks to iSCSI Counters,
Open Flow, and ACL Optimization.
You can configure only two of these features at a time.
• To allocate the number of FP blocks for VLAN open flow 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, 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. You must also allocate the slices for CAM
optimization.
To display the number of FP blocks that is allocated for the different VLAN services, use the show cam-acl-vlan command.
After you configure the ACL VLAN groups, reboot the system to store the settings in nonvolatile storage. During CAM initialization,
the chassis manager reads the NVRAM and allocates the dynamic VCAP regions.
