For an upstream channel to be in-service, there must be at least one downstream channel in-service that is providing it
with supervision.
Caution: The supervision for at least one upstream channel that is associated with a fiber node must be carried on at least
one primary-capable downstream channel that is also associated with that fiber node. Otherwise, CMs cannot initialize at
the fiber node. Fiber nodes with this problem will show up on the
show cable fiber-node not-valid
output.
Supervision CLI Commands
The commands in the table below configure supervision, and display slot and channel supervision information. Examples
are found in the following sections.

Description
Command
This command controls the assignment of supervision from
a logical upstream channel to a downstream channel.
At least one, and as many as 16 downstream channels can
be assigned to carry the supervision for 12 individual
upstream channels. For minimum redundancy at least two
downstream channels should be assigned.
Use the [no] option to disable supervision on the specified
downstream port.
