VLAN Translation Policy
Double-tagged VLAN
ONT: Packets that are sent upstream by
the HGW are tagged with a user VLAN.
The ONT transparently transmits the user
VLAN.
OLT: translates the VLAN tag (user
VLAN <-> S-VLAN+C-VLAN).
Double-tagged VLAN
ONT: Packets that are sent upstream by
the HGW are tagged with a user VLAN.
The ONT translates the user VLAN (user
VLAN <-> C-VLAN). The C-VLAN is
an inner VLAN tag that differentiates
users.
OLT: adds an S-VLAN tag to the packets
(C-VLAN <-> S-VLAN+C-VLAN).
Gateway ONT
Single-tagged VLAN
(recommended)
ONT: VLANs are configured for the
ONTs on the same network in a unified
manner, and the ONTs have the same C-
VLAN. The ONT adds a C-VLAN tag to
packets.
OLT: translates the VLAN tag (C-VLAN
<-> S-VLAN).
Single-tagged VLAN
ONT: VLANs are configured for the
ONTs on the same network in a unified
manner, and the ONTs have the same C-
VLAN. The ONT adds a C-VLAN tag to
packets.
OLT: transparently transmits the VLAN.
Double-tagged VLAN
ONT: VLANs are configured for the
ONTs on the same network in a unified
manner, and the ONTs have the same C-
VLAN. The ONT adds a C-VLAN tag to
packets.
OLT: translates the VLAN tag (C-VLAN
<-> S-VLAN+C-VLAN').
Note:
l
UserVLAN: VLAN carried by upstream packets of user-side devices, U for short.
l
C-VLAN: VLAN added based on the ONT/ONU port. For details, see the description of
the Double-tagged VLAN S+C.
l
Double-tagged VLAN S+C: C indicates the inner VLAN (C-VLAN) and S indicates the
outer VLAN (S-VLAN).
