4.17.2 VLANs SVL (Shared VLAN Learning Configuration) Configuration

The Shared VLAN Learning Configuration page allows for controlling SVL configuration on the switch. In SVL, one or more VLANs map to a Filter ID (FID). By default, there is a one-to-one mapping from VLAN to FID, in which case the switch acts as an IVL bridge, but with SVL multiple VLANs may share the same MAC address table entries.

Figure 4-71. Shared VLAN Learning Configuration

The Shared VLAN Learning Configuration page has the following parameters:

  • Delete: A previously allocated FID can be deleted using button
  • FID: FID is the ID that VLANs get learned on in the MAC table when SVL is in effect. No two rows in the table can have the same FID and the FID must be a number between 1–63.
  • VLANs: List of VLANs is mapped into FID. The syntax is as follows: Individual VLANs are separated by commas. Ranges are specified with a dash separating the lower and upper bound. The following example maps VLANs 1, 10, 11, 12, 13, 200, and 300: 1,10-13,200,300. Spaces are allowed in between the delimiters. The range of valid VLANs is 1–4095. The same VLAN can only be a member of one FID. A message is displayed if one VLAN is grouped into two or more FIDs. All VLANs must map to a particular FID, and by default VLAN x maps to FID x. This implies that if FID x is defined, then VLAN x is implicitly a member of FID x unless it is specified for another FID. If FID x does not exist, a confirmation message is displayed, asking whether to continue adding VLAN x implicitly to FID x.
