4.2.6.4.1.3.5 Extended Access Link (SU only)
This link type extends the Access mode’s functionality by allowing it to work with
up to 8 different VLAN IDs instead of one. Based on a predefined set of rules, the
SU will apply a specific VLAN ID and priority tag to untagged frames that are
routed from Ethernet to WLAN. The same VLAN IDs from the configured set of
rules will be used to filter the VLAN tagged frames that are routed from WLAN to
Ethernet, then the SU removes the tags.
4.2.6.4.1.3.6 Extended Trunk Link (SU only)
This link type extends the Trunk mode’s functionality by allowing it to also work
with VLAN untagged frames instead of dropping them. All untagged frames
received via Ethernet will be tagged with a predefined VLAN ID and routed to
WLAN. Consequently, tagged frames received over WLAN that match this VLAN ID
will be untagged before being routed to Ethernet. The exact behavior is shown in
Table 4-13.
Accept from Wireless Single tagged frames:
 If Forwarding is disabled
 If Forwarding is enabled, only frames with VLAN ID values which
are included in the Forwarding List
Double tagged frames:
 If Forwarding is disabled
 If Forwarding is enabled, only frames with Service Provider VLAN
ID values which are included in the Forwarding List
Tag Ins ert N o
Tag Remove No
NOTE
The following units management limitations apply when using a Service Provider Link:
 The unit can be managed only with tagged frames: VLAN ID - Management must be other than
65535.
 To enable proper management, all units in a cell (the AU and all SUs served by it) must use the
VLAN ID - Management.
 The VLAN ID - Management must differ from the Customer's VLAN ID - Data.
