4.2.6.4.1.3.2 Trunk Link Trunk Link transfers only tagged frames, as 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.
Table 4-8 summarizes the functionality of the data port for a Trunk link.
