Access Control List (ACL) VLAN Groups
and Content Addressable Memory (CAM)
This chapter describes the access control list (ACL) VLAN group and content addressable memory (CAM)
enhancements.
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

Introduced on the MXL platform.
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.
