7-2 Multiple ESS and VLAN
Station 1 relays communications via the ZyAIR within the Multi-ESS coverage area and with AP X if it
moves to the RD ESS coverage area. Similarly, station 2 relays communications via the ZyAIR within the
Multi-ESS coverage area and with AP Y if it moves to the Sales ESS coverage area.

7.2 VLAN
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical
networks. Stations on a logical network can belong to one or more groups. Only stations within the same
group can talk to each other.
The ZyAIR supports 802.1q VLAN tagging. Tagged VLAN uses an explicit tag (VLAN ID) in the MAC
header of a frame to identify VLAN membership. The ZyAIR can identify VLAN tags for incoming Ethernet
frames and add VLAN tags to outgoing Ethernet frames.
Configure VLAN (virtual LAN) with multi-ESS to extend the wireless logical grouping to the wired
network. Each ESS is assigned a unique VLAN ID.
7.2.1 Management VLAN ID
The Management VLAN ID identifies the “management VLAN”. A device must be a member of this
“management VLAN” in order to access and manage the ZyAIR. If a device is not a member of this VLAN,
then that device cannot manage the ZyAIR.
