l Run the display cable eqam video statistics output command to query packet statistics
of a TS on the video service output end.
Check whether the TS contains the ordered program, whether the program has been sent
to the STB, and whether the TS traffic is normal.
15.4.1.12 Configuring the BTV Service
A cable modem (CM) connects to a distributed cable modem termination system (D-CMTS)
through a cable and provides the multicast service for users.
Context
All home services use a service VLAN (S-VLAN) and the S-VLAN is globally configured. If
the S-VLAN has been configured for other home services, use the S-VLAN for the multicast
service.
Data Plan
Table 15-41 Data plan for the multicast service
Item Data
VLAN ID of the multicast S-VLAN: 100; type of the VLAN: smart
Uplink ports Forwarding Dynamic Host Configuration Protocol (DHCP),
broadband, and VoIP packets: 0/4/0
Forwarding cable modem (CM) management, VoD, and multicast
packets: 0/5/0
Procedure
Step 1 Create an S-VLAN.
The S-VLAN is a user-side service VLAN between the optical line terminal (OLT) and the D-
CMTS. The OLT works in Layer 3 forwarding mode.
huawei(config)#vlan 100 smart
Step 2 Create a CM S-VLAN.
The CM S-VLAN identifies a CM service flow. After the CM S-VLAN is configured, the OLT
automatically creates a CM service flow when the CM goes online.
NOTE
l The cable service-vlan vlanid command is used to configure a global S-VLAN for CM services. After the
configuration, all CM services of the D-CMTSs connected to the same OLT use the same VLAN. When the
number of IP address segments planned for an OLT is less than eight, this command is recommended.
l The cable service-vlan vlanid frameid/slotid command is used to configure an S-VLAN for CM services
on a specified D-CMTS. After the configuration, the D-CMTS does not use the global S-VLAN. When the
number of IP address segments planned for an OLT is greater than eight, this command is recommended.
