Term heading Description heading
Attaching an ACL individually to VLAN interfaces is similar to the behavior of ACL-VLAN mapping storage
in CAM prior to the implementation of the ACL VLAN group functionality.
cam-acl-vlan
Configure the number of flow processor (FP) blocks of CAM allocated to ACL VLAN services on the switch.
Syntax
cam-acl-vlan {default | vlanopenflow <0-2> | vlaniscsi <0-2> | vlanaclopt
<0-2>}
Parameters
default Reset the number of FP blocks to the default value. By default, 0 FP blocks of
CAM are allocated for ACL VLAN services, such as iSCSI counters, Open Flow, and
ACL VLAN optimization.
NOTE: CAM optimization for ACL VLAN groups is not enabled by default. You
must allocate FP blocks of ACL VLAN CAM to enable ACL CAM optimization.
vlanopenflow
<0-2>
Allocate a number FP blocks of CAM for VLAN Open Flow operations.
vlaniscsi <0-2> Allocate a number FP blocks of CAM for VLAN iSCSI counters.
vlanaclopt <0-2> Allocate a number of FP blocks of CAM for CAM optimization of ACL VLAN
operation.
Default To reset the number FP blocks allocated for ACL VLAN processes, enter the default keyword with the
cam-acl-vlan command. By default, 0 FP blocks are allocated for ACL VLAN operations on the switch.

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, Open Flow and ACL VLAN optimization. You
can configure CAM FP blocks for only two of these ACL VLAN services at a time.
