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.
