History
Version 9.3(0.0)
Introduced on the MXL 10/40GbE Switch IO Module
platform.
Usage
Information
You can have up to eight different ACL VLAN groups at any given time. When you
configure an ACL VLAN group, you enter the ACL VLAN Group Configuration
mode.
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 signficiantly 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.
