Trunk Link
Trunk Link transfers only tagged frames, since all devices connected to
the unit are VLAN aware: Only tagged data frames received on the
Ethernet or wireless link ports are forwarded.
CAUTION
It is not recommended that you configure a unit as a Trunk Link with the VLAN ID-
Management parameter set at 65535, as it does not forward any 'NO VLAN'
management frames to its other port making it impossible to manage devices connected
behind the unit that are also configured with 'NO VLAN'.
If the VLAN Forwarding option is enabled, a data frame received with a
VLAN ID that is not a member of the unit's VLAN Forwarding List is
discarded.
NOTE
If the VLAN Forwarding option is enabled, be sure to include the VLAN ID-
Management value of all units that should be managed via the wireless port of the unit,
in the Forwarding List.
If the VLAN Relaying option is enabled in an AU, a data frame relayed
with a VLAN ID that is not a member of the unit's VLAN Relaying List is
discarded.
NOTE
If the VLAN Relaying option is enabled and you manage your devices from behind an
SU unit, be sure to include the VLAN ID-Management value of all units to be managed
when relaying via the wireless port of the AU unit, in the Relaying List. If the VLAN
Forwarding option is also enabled in the AU, these VLAN IDs should also be included in
the Forwarding List.
