Addendum

• 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.
You can use the no version of these commands to 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.
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, you must
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.
member vlan
Add VLAN members to an ACL VLAN group.
Syntax
member vlan {VLAN-range}
Parameters
VLAN-range
Enter the member VLANs using comma-separated VLAN IDs,
a range of VLAN IDs, a single VLAN ID, or a combination. For
example:
Comma-separated: 3, 4, 6
Range: 5-10
Combination: 3, 4, 5-10, 8
Default None

and MXL platforms
Usage
Information
At a maximum, there can be only 32 VLAN members in all ACL VLAN groups. A
VLAN can belong to only one group at any given time.
You can create an ACL VLAN group and attach the ACL with the VLAN members.
The optimization is applicable only when you create an ACL VLAN group. If you
apply an ACL separately on the VLAN interface, each ACL has a mapping 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.
