Usage Information The VLAN ContentAware Processor (VCAP) application is a pre-ingress CAP that modifies 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 fixed groups and the other two are for
dynamic groups. Out of the total of two dynamic groups, you can allocate zero, one, or two flow processor (FP)
blocks to iSCSI Counters, OpenFlow and ACL Optimization. You can configure only two of these features at a
point in time.
