Usage Information The VLAN ContentAware Processor (VCAP) application is a pre-ingress 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 ow processor (FP)
blocks to iSCSI Counters, OpenFlow and ACL Optimization. You can congure only two of these features at a point
in time.
