Cam-Acl-Vlan - Dell C9000 Series Reference Manual

Term heading Description heading
Usage Information You can configure up to eight different ACL VLAN groups at a time on the switch. When
you configure an ACL VLAN group, you enter ACL VLAN Group configuration mode.
You can also configure the ACL VLAN group in Configuration Terminal Batch mode
that applies the configurations to the chassis in a dual-homing setup.
To avoid the problem of excessive consumption of CAM area, you can configure ACL
VLAN groups that combines all the VLANs that are applied with the same ACL in a
single group. A unique identifier for each of ACL attached to the VLAN is used as a
handle or locator in the CAM area instead of the VLAN id. This method of processing
significantly reduces the number of entries in the CAM area and saves memory space in
CAM.
You can create an ACL VLAN group and attach the ACL with the VLAN members.
Optimization is applicable only when you create an ACL VLAN group. If you apply an
ACL separately on the VLAN interface, each ACL maps with the VLAN and increased
CAM space utilization occurs.
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
vlanopenflow
<0-2>
vlaniscsi <0-2>
vlanaclopt <0-2>
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.
Allocate a number FP blocks of CAM for VLAN Open Flow
operations.
Allocate a number FP blocks of CAM for VLAN iSCSI counters.
Allocate a number of FP blocks of CAM for CAM optimization of
ACL VLAN operation.
