Table 2-11: VLAN Data Port Functionality Summary – Access Link
Legend: VID-D: VLAN ID-Data
PID-D: VLAN Priority-Data
# Trunk Link – Transfers only tagged frames, because all
devices connected to it are VLAN-aware:
Only tagged data frames received on Ethernet or wireless
link ports are forwarded.
If the VLAN Forwarding option is enabled, a received data
frame with a VLAN ID that is not a member of the unit’s
VLAN Forwarding List will be discarded.
If the VLAN Relaying option is enabled in an AU, a WLAN
relayed data frame with a VLAN ID that is not a member
of the unit’s VLAN Relaying List will be discarded.
The following table summarizes the functionality of the
data port for a Trunk link.
Action Data Port (SU)
Accept from Ethernet Untagged frames
Accept from Wireless Tagged frames, matching VID-D
Tag Insert VID-D, PID-D (to wireless)
Tag Remove Yes (to Ethernet)
WARNING:
It is not recommended to configure a unit as a Trunk Link with
VLAN ID - Management (or VLAN ID - Voice & Management) of 65535, as it
will not forward any ‘NO VLAN’ management frames to its other port. It will be
impossible to manage devices connected behind the unit that are also
configured with ‘NO VLAN’.
NOTE:
If VLAN Forwarding is enabled, make sure to include in the Forwarding
List the VLAN ID – Management (or VLAN ID - Voice & Management)
of all units that should be managed via the wireless port of the unit.
NOTE:
If VLAN Relaying is enabled and you manage your devices from behind
an SU unit, make sure to include in the Relaying List the VLAN ID –
Management (or VLAN ID - Management & Voice) of all units that
should be managed when relaying via the wireless port of the AU unit.
If also VLAN Forwarding is enabled in the AU, these VLAN IDs should
also be included in the Forwarding List.
