2.
All packets sent by the PC and STB are untagged. The corridor switch adds VLAN tag 10
to the HSI service packets and adds VLAN tag 20 to the VoD service packets.
3.
The CMC adds VLAN tag 100 to the HSI service packets and CM management packets
(CM Mg) and adds VLAN tag 200 to the VoD service packets.
Figure 15-7
VLAN tag transparent transmission (VPN access)
In the preceding network, IP addresses are allocated and service flows and VLAN tags are
processed as follows:
1.
The CM uses the dynamic IP address allocated by a DHCP server.
2.
The enterprise switch statically configures the IP address of the PC and adds VLAN tag
200 to VPN data packets.
3.
The CMC adds VLAN tag 100 to the CM management packets (CM Mg) and transparently
transmits the VLAN tag of the VPN data packets.
NOTE
The preceding VLAN planning applies to the CMC, regardless of whether the CMC is deployed in standalone
NE or centralized management mode.
Restrictions and Limitations
l
In home access services, although the CMC supports multiple service VLANs (S-VLANs),
all home access services are within the same broadcast domain. Therefore, the home access
services do not support VLAN-based broadcast domains.
l
In centralized management mode, one GPMD board supports a maximum of 1024 home
access S-VLANs.
15.3 Service Configuration on a D-CMTS That Works as a
GPON Remote Extended Frame on a Layer 3 Network
This section describes how to configure services, including home services, L2VPN enterprise
service, and wireless local area network (WLAN) hotspot radio backhaul service, on an optical
line terminal (OLT) when a distributed cable modem termination system (D-CMTS) works as
a GPON extended frame on a Layer 3 network. The MA5603T equipped with the SCUV, GPMD,
and SPUF boards is used as an example.
