General System Configuration
Configuring VLAN Support

Management VLAN. A management VLAN can be configured for secure
management access to the access point. The management VLAN is for
managing the access point through remote management tools, such as the Web
interface, SSH, Telnet, or SNMP. The access point only accepts management
traffic that is tagged with the specified management VLAN ID.
Tagged and Untagged VLANs. VLAN support is always enabled on the
access point and can not be disabled. Traffic passed to the wired network is
tagged with the appropriate VLAN ID, either an assigned client VLAN ID, a
default VLAN ID, or the management VLAN ID. By default, only one untagged
VLAN ID is configured. Traffic passed to the wired network from the untagged
VLAN does not include a VLAN tag.
Similarly, traffic received from the wired network must be tagged with a
known VLAN ID, either an assigned client VLAN ID, a default VLAN ID, or the
management VLAN ID. Received traffic that has no tag is passed to the access
point's untagged VLAN, if configured, otherwise it is dropped. Received traffic
that has an unknown VLAN ID or is tagged with the VLAN ID of the configured
untagged VLAN is dropped.
As part of ensuring appropriate VLAN support, configure the attached
network switch port to support IEEE 802.1Q tagged VLAN frames from the
access point's management VLAN ID, default VLAN IDs, and other client VLAN
IDs.
You must not use the same VLAN ID for both a statically configured VLAN and
for a VLAN dynamically configured by a RADIUS server policy. If you dynam-
ically assign a VLAN that has already been statically assigned to a VLAN or to
the management VLAN or untagged VLAN, the dynamic authentication will
fail and will continue trying to authenticate.
Web: Setting A Management VLAN
The Network Setup – Ethernet screen configures the management VLAN ID.
The Web interface enables you to modify these parameters:
■
Management VLAN: Indicates the VLAN that will be used to route all
management traffic to and from the access point. (The default is 1.)
[Update]: Updates the Management VLAN.
