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.
