The following command is used to display the associations of upstream interfaces to a state machines, as well as the
current state for each state machine:
show cable spectrum-group [<SM_ID>] state
Here is an example of the output of this command:
Spectrum Current
Interface Enabled Group State
0/0/0 Y 1 2
0/0/1 Y 1 1
0/0/2 N 1 3
0/0/3 N 1 2
0/0/4 Y 2 1

0/1/11 N none none
1/0/0 Y 1 5
1/1/2 Y 1 4
2/0/0 Y 2 3
Only interfaces associated with spectrum groups are shown.
Use the following command to display the definition of a state machine:

Where: SM_ID is the state machine identifier. Range = 1-40.
The output of the CLI command show cable spectrum-group 1 might take the form:
