cam-acl-vlan
Allocate the number of flow processor (FP) blocks or entries for VLAN services and processes.
Syntax
cam-acl-vlan { default | vlanopenflow <0-2> | vlaniscsi <0-2> | vlanaclopt
<0-2>
Parameters
default Reset the number of FP blocks to default. By default, 0 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.
vlanopenflow
<0-2>
Allocate the number of FP blocks for VLAN open flow operations.
vlaniscsi <0-2> Allocate the number of FP blocks for VLAN iSCSI counters.
vlanaclopt <0-2> Allocate the number of FP blocks for the ACL VLAN optimization feature.
Default If you use the default keyword with the cam-acl-vlan command, the FP blocks allocated for VLAN
processes are restored to their default values. No FP blocks or dynamic VLAN Content Aware Processor
(VCAP) groups are allocated for VLAN operations by default.

Version Description
9.3(0.0) Introduced on the S4810 and Z9000 platforms.
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.
show cam-usage

partitions).

(OPTIONAL) Enter the keyword acl to display Layer 2 and Layer 3 ACL CAM
usage.
