Allocating FP Blocks for VLAN Processes
The VLAN contentaware processor (VCAP) application is a pre-ingress CAP that modies 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 xed 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 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, use the cam-acl-vlan vlanaclopt <0-2> command.
