Administrator Guide

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.

Command History
Version Description
9.10(0.0) Introduced the Configuration Terminal Batch mode on C9010.
9.9(0.0) Introduced on the C9010.
9.5(0.1) Introduced on the Z9500.
9.3(0.0) Introduced on the S4810 and Z9000.
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. Use this command in Configuration Terminal Batch mode to configure in a
dual-homing setup.
