SW3-L3
GIGABIT/FAST ETHERNET SWITCH/ROUTER TYPE SW3-L3
61/180
USER GUIDE - M0SW3M1902Iv07 - V06 February 2019
In the SW3-L3, the VLAN are also simultaneously the logical interfaces in which routing is
performed, and that is why the IP address and the corresponding mask is included as part
of the configuration of the VLAN.

There is a global parameter that affects all the VLANs, which determines the level 2
switching operation, called Overlapping.
•
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 5.3.1).
FIGURE 30 shows an example for using the
Overlapping
Enable
parameter.
