SP-VID per CPE, CPE Port VLAN Filtering (Separate IP MGMT
for CO/CPE)
Management Traffic toward CO and CPE may belong to different MGMT VLANs. To
achieve this functionality, the following configuration should be applied:
A port on the CO NE should be configured with two TRFC VLANs:
TRFC VLAN with STACKED membership will serve Tagged Traffic (VID=20 in
the illustration below). All Customer traffic, passed through CPE is tagged – natively
from Customer Side, or being modified on UNTAGGED port – where default Port
VID is added
TRFC VLAN with UNTAGGED membership will serve Untagged Traffic (VID=200
in the illustration below). Only CPE Management traffic should be untagged.
MGMT VLAN ID on the CO NE (VID=100 in the illustration below) should NOT
include HSL port; i.e. CO Management traffic should not pass to the CPE on Customer
side
MGMT VLAN ID on CPE NE (VID=200 in the illustration below) should be set on CPE
NE only. The same VID on the CO NE is configured as a TRFC VLAN (see above).
The next drawing illustrates configuration and traffic flow in case of CO/CPE Different
