6-15
1-4292967295 is the Service Flow Identifier (SFID).
cr is a command return, which displays QoS service flow statistics for all
SFIDs.
Enabling the Downstream Port
The downstream port is in an administrative shut-down state by default and must be
enabled to function.
Follow these steps to enable the downstream port:
1. To enable the downstream port, use the no cable downstream shutdown
command in Interface Configuration mode, as shown below:
MOT(config-if)#no cable downstream shutdown
2. To verify that the downstream port is enabled, use the show interface cable
command in Interface Configuration mode, as shown below:
MOT(config-if)#show interface cable <x>/<y>
where:
x is the slot number of the cable module.
y is the cable interface number, which is 0.
Managing the Downstream Channel
The tasks in this section involve some parameters that you may choose to change. If a
parameter default is satisfactory, you can ignore its associated task.
The tasks in this section are used to manage the operation of the downstream channel:
• Configuring the Downstream Interleave Depth
• Setting the Downstream Power Level
• Resetting a Downstream Port
• Reserving Downstream Bandwidth
• Unreserving Downstream Bandwidth
• Testing RF Carrier Modulation
