But with VLANS, you can change the LAN segment assignment of
an end node connected to the switch through the switch’s AT-S41
management software. VLAN memberships can be changed any
time through the management software without moving the
workstations physically, or having to change group memberships
by moving cables from one switch port to another.
Additionally, a virtual LAN can span more than one switch. This
means that the end nodes of a VLAN do not need to be connected
to the same switch and so are not restricted to being in the same
physical location.
VLAN Modes An AT-8326GB stack features two VLAN modes: 802.1Q and port-based.
The 802.1Q VLAN mode complies with the IEEE 802.1Q standard and
supports two types of VLANs:
❑ Untagged VLANs
❑ Tagged VLANs
Untagged and tagged VLANs are described in the next section. The Port-
based VLAN mode is described on page 106.
