FIGURE 23

VLANs

menu configuration page

The screen associated to the

VLANs

menu has four distinct sections, which are described

below.

There is a global parameter that affects all the VLANs.

•

Overlapping Enable.

It sets the switch internal operation mode as regards the

management of the MAC addresses of the different VLANs. The operation mode is

IVL

(

Independent

VLAN

Learning

) by default. The equipment operates in

SVL

mode

(

Shared

VLAN

Learning

) with the option selected.

The

SVL

(

Overlapping

Enabled

) mode is necessary when using topologies with

several VLANs when there is an interface with access to more than one of the

configured VLANs, that is, that

the VLANs share some user interface

, and that the

clients operate with UNTAGGED frames

. In these cases, the traffic exclusion is

done through the

access control lists

determined for each one of the interfaces

(see the

VID ACL

parameter in section 5.4).

FIGURE 24 shows an example for using the

Overlapping

Enable

parameter.
