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.
You can configure only two of these features at a time.
• To allocate the number of FP blocks for VLAN open flow operations, use the cam-acl-vlan
vlanopenflow <0-2>
command.
• To allocate the number of FP blocks for VLAN iSCSI counters, use the cam-acl-vlan vlaniscsi
<0-2> command.
• To allocate the number of FP blocks for ACL VLAN optimization, use the cam-acl-vlan
vlanaclopt <0-2> command.
To reset the number of FP blocks to the default, use the no version of these commands. By default, zero
groups are allocated for the ACL in VCAP. ACL VLAN groups or CAM optimization is not enabled by
default. You must also allocate the slices for CAM optimization.
To display the number of FP blocks that is allocated for the different VLAN services, use the show cam-
acl-vlan command. After you configure the ACL VLAN groups, reboot the system to store the settings
in nonvolatile storage. During CAM initialization, the chassis manager reads the NVRAM and allocates the
dynamic VCAP regions.
