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.
