For tagged packets, the VPL ID will be their VLAN tag.
For untagged packets, the VPL ID will be None.
For packets received from the network, the forwarding decision will be according
to the packet's VPL ID. If the VPL ID is unknown (either None or not included in
the list of VPL IDs defined for any of the existing, non-transparent Service
Profiles), the system will assume this is a transparent VLAN packet (if at least one
transparent Service is defined) and transfer it with the original VLAN tag (or
untagged if there is no VLAN tag).

Profiles), the system will assume this is a transparent VLAN packet (if at least one
transparent Service is defined) and transfer it with the original VLAN tag (or
untagged if there is no VLAN tag).
When set to Off, data packets sent from the Base Station to the backbone will be
transferred with a VLAN tag according to the VPL ID. The VLAN ID in tagged
frames arriving from the wireless network will be replaced by the VPL ID. For
packets received from the network, the forwarding decision will be according to
the Forwarding Rule defined in the Service Profile with a matching VPL ID.

To avoid conflicts, a transparent Service Profile cannot be assigned to a Service if
the Service's VLAN ID list includes a VLAN ID that is equal to any of the already
assigned VPL IDs.

VPL ID
A Virtual Private Link ID to be used in the backbone behind the Base Station. The
VPL ID parameter is applicable only to Service Profiles with VLAN Transparency
Mode Off.
VPL ID parameter is applicable only to Service Profiles with VLAN Transparency
Mode Off.
To avoid conflicts, it is not allowed to define a VPL ID that is identical to any of the
VLAN IDs in the already assigned transparent Services (Services using a Service
Profile with VLAN Transparency Mode On).
VLAN IDs in the already assigned transparent Services (Services using a Service
Profile with VLAN Transparency Mode On).
Several Service Profiles may share the same VPL ID. However, the following rules
must be met:

NOTE
The combination of VLAN Transparency Service On, Hybrid VLAN Mode Off and an empty VLAN
List means that all packets are forwarded. This combination should be used only if the Service
Provider can ensure that there will not be conflicts between VLAN IDs used by devices behind the
SU and existing VPL IDs.
