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.
