Cause
There are two possible reasons:
1. Either the port is intentionally not in use, and therefore is provisioned “Not
Monitored”, but mistakenly an input signal is applied (due to erroneous
routing of intermediate cabling for example), or
2. although an input signal is applied, the port is mistakenly provisioned “Not
Monitored”.
Actions
Change the port monitoring mode to “Monitored”, or check the cabling (and
re-arrange if necessary).
