3.22.3 Shared VLAN Learning Configuration

Shared VLAN Learning (SVL) allows for frames that are initially classified to a particular VLAN (based on Port VLAN ID or VLAN tag information) to be bridged on a shared VLAN. In SVL, two or more VLANs are grouped to share common source address information in the MAC table. The common entry in the MAC table is identified by a Filter ID (FID).

Command Syntax:

svl fid <fid> vlan <vlan_list>
no svl fid { <fid_list> | all }
Table 3-99. Command Description

Argument

Description

Parameter

<fid>

The FID must be a number between 1 and 63.

<vlan_list>

List of VLANs mapped into FID. Individual elements are separated by commas and ranges are specified with a dash.

<fid_list> | all

List of one, more or all FIDs.

Default

N.A

Mode

Global Configuration mode

Usage

Create SVL. To change all VIDs currently mapped to the FID back to being independent (IVL), use the ‘no’ version of the command.

Example

Example 1:

Let VID 2, 4 and 20-200 map to the same shared VLAN, 13.

(config)# svl fid 13 vlan 2,4,20-200

Example 2:

Let all VLANs currently mapped to FID 7 and 10 return to Independent VLAN Learning (IVL).

(config)# no svl fid 7,10
