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.
