Management VLAN Setup
In the figure above, to access and manage the Zyxel Device from computer
A
, the Zyxel Device and
switch
B
’s ports to which computer
A
and the Zyxel Device are connected should be in the same VLAN.
A Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple logical
networks. Devices on a logical network belong to one group. A device can belong to more than one
group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same
group(s); the traffic must first go through a router.
VLAN also increases network performance by limiting broadcasts to a smaller and more manageable
logical broadcast domain. In traditional switched environments, all broadcast packets go to each and
every individual port. With VLAN, all broadcasts are confined to a specific broadcast domain.
Wireless Bridge VLAN ID
Wireless bridge VLAN allows you to have clients in different WiFi networks appear to be in the same
virtual network using VLAN IDs. VLAN IDs are sent across the wireless bridge so that only clients with the
same VLAN ID receive that network traffic. See
wireless bridge.
In the figure below, a client (
C2
) in the branch office wants to connect to the main office (
Y
). The
branch office client (
C2
) can connect to the main office network using the
VLAN ID 10
. However, the
branch office client (
C2
) cannot connect to the to the main office network using the
VLAN ID 20
because that VLAN ID does not exist in the main office network. To bridge the branch office network
and the main office network, the VLAN IDs you set on the Zyxel Device (
X
) should be the same as the
VLAN IDs you set on the root AP (
Y
).
