AT-S45 User’s Guide

But with VLANS, you can change the LAN segment assignment of

an end node connected to the switch through the switch’s AT-S45

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 The AT-9410GB switch features two VLAN modes: 802.1Q and port-

based. The 802.1Q VLAN mode of the switch 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 102.
