1.
The transmit power of the downstream channels meets site requirements.

command to check whether the RF port parameters meet site requirements.
2.
The signal-to-noise (SNR) ratio of the upstream channels meets site requirements.
Run the

command to check whether the RF port parameters meet site requirements. A greater SNR
ratio results in better signal quality. The recommended SNR ratio is greater than 30 dB.
16.3.2.10 Configuring the L2VPN Enterprise Service(on the CMC)
In the upstream direction, a cable modem (CM) connects to a distributed cable modem
termination system (D-CMTS) through a cable. In the downstream direction, the CM connects
to a switch to provide the L2VPN enterprise service to the users connected to the switch.
Context
An L2VPN S-VLAN can be configured through a CM configuration file or commands. Only
one mode is used each time generally. If both modes are used, the S-VLAN configuration through
commands preferentially takes effect on the system when the CM goes online.
l
S-VLAN configuration through a CM configuration file: Run the
vlan
command to add a
CM S-VLAN and run the
port vlan
command to add the uplink port for the CM to the S-
VLAN. Then, run the
cable service-vlan
command to make the CM go online. The L2VPN
S-VLAN is specified in the CM configuration file. When the CM goes online, the system
obtains the L2VPN S-VLAN from the CM configuration file and automatically creates
L2VPN service flows.
l
S-VLAN configuration through commands: Manually configure the L2VPN S-VLAN on
the system. For details, see the following procedure.
