VLAN
All ONUs add the same C-VLAN tag to
packets.
The OLT implements VLAN translation: C->S

Single-
tagged
VLAN
ONUs transparently transmit upstream packets
with M-VLANs sent from HGW. Multicast
packets are replicated downstream with M-
VLAN unchanged.
The OLT replicates multicast packets based on
PON ports with M-VLAN unchanged.
Single-
tagged
VLAN
ONUs translate the upstream VLANs sent from
HGW to M-VLANs.
The OLT replicates multicast packets based on
PON ports with M-VLAN unchanged.

tagged
VLAN
ONUs transparently transmit the upstream U-
VLANs sent from HGW.
The OLT implements VLAN translation: U->S.
Double-
tagged
VLAN
ONUs transparently transmit the upstream U-
VLANs sent from HGW.
The OLT implements VLAN translation: U->S
+C.
Note:
l UserVLAN: VLAN carried by upstream packets of user-side devices, U for short.
l C-VLAN: VLAN added based on the ONU/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).
l Double-layer VLAN S+C': C' indicates the translated inner VLAN (C'-VLAN) and S
indicates the outer VLAN (SVLAN).
l Single-tagged S-VLAN: Single-tagged VLAN marked or translated by the OLT. It is
generally used in a single-tagged VLAN translation scenario.
l C<->S+C': Bidirectional VLAN translation: translates the inner C-VLAN and then adds
one outer S-VLAN.
l C<->S+C: Bidirectional VLAN translation: maintains the inner C-VLAN and adds one
outer S-VLAN.
