The packets of the
VoIP service do
not carry a VLAN
tag.
A service flow is
created between a
CM and a D-
CMTS.
CM management packets
and VoIP packets carry the
same VLAN tag.

services at Layer 3, the
OLT adds a unique
VLAN tag to the

enterprise
service
The packets of the
L2VPN enterprise
service do not
carry a VLAN tag.
Two service flows
are created
between a CM and
a D-CMTS. One is
the default service
flow and the other
is the VPN service
flow.
CM management packets
and enterprise packets
carry different VLAN tags.
The VLAN pre-configured
for the packets of the
L2VPN enterprise service
must be the same as that
configured in the CM
configuration file.
