networking (HGW

l Untagged
upstream packets
of HGWs: ONUs
map C-VLANs
based on user
ports.
l Tagged upstream
packets of HGWs:
ONUs translate
user VLANs to C'-
VLANs.
[Remark 1]
HGWs (xDSL
upstream
transmission): ONUs
translate PVCs to C'-
VLANs.
Note
l To ensure traceability of users and finer-grained QoS control and management of users and
services, plan per user per service per VLAN (PUPSPV) for the Internet access service.
Considering OLT capacity and VLAN scalability, use dual VLANs (S-VLAN+C-VLAN)
on the OLT to differentiate users for the Internet access service.
l The outer S-VLAN, which identifies services and physical location, can be allocated based
on the OLT, PON board (recommended), or PON port (recommended). The inner C-VLAN
identifies users. User C-VLANs are unique in one S-VLAN.
NOTE
It is recommended that you associate C-VLAN IDs with PON ports, optical splitters, and ONU ports
to ensure C-VLAN uniqueness and to facilitate location. Example: C-VLAN ID = 256 x PON port
ID + 32 x Split ratio x (Optical port ID - 1) + ONU port ID + 1
l It is recommended that you use stacking VLANs as S-VLANs so that security features,
such as PPPoE+/option 82, and anti-MAC attack, and anti-MAC spoofing can be easily
deployed.
