Access Control List (ACL) VLAN Groups and
Content Addressable Memory (CAM)
This section describes the access control list (ACL) virtual local area network (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
Command Modes CONFIGURATION (conf-acl-vl-grp)
Supported Modes Full–Switch
Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.3(0.0) 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.
