Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

The VLAN ContentAware Processor (VCAP) application is a preingress 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 FP blocks to iSCSI Counters, OpenFlow 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 feature, 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, and you need to allocate the slices for CAM optimization.

To display the number of FP blocks that is allocated for the different VLAN services, you can use the show cam-acl-vlan command. After CAM configuration for ACL VLAN groups is performed, reboot the system to enable the settings to be stored in nonvolatile storage. During the initialization of CAM, the chassis manager reads the NVRAM and allocates the dynamic VCAP regions.
