Use the following command to display one or all triggers that have been defined:
show cable spectrum-group trigger [<trigger_ID>]
The system response will take the following form:
Trigger Type
0 Manual
1 degradation ufec_err > 5 OR fec_err > 15 AND snr < 20
2 degradation ufec_err > 15 OR fec_err > 25 AND snr < 20
3 improvement ufec_err < 5 AND fec_err < 15 AND snr > 20
4 improvement ufec_err < 15 AND fec_err < 25 AND snr > 20

6 period 3600
Use the following command to display the history of state transitions for the state machine associated with each
upstream channel:
show interface cable-upstream <slot/us-port> spectrum-group history [detail]
Where:
slot is the chassis slot number of the CAM. Range = 0-15
us-port is the upstream port of the CAM
detail provides additional reasons for the state transition.
An example of the output of this command is shown below:
P=Periodic T=TOD D=Degradation I=Improvement S=Startup M=Manual
