With this configuration:

Note Even if the link does not flap due to failure of the link, and port guard is not enabled, the port goes into
a down state if too many invalid FLOGI requests are received from the same host. Use the shut and the
no shut commands consecutively to bring up the link.
This example shows the internal information about a port in down state because of trustsec violation:
Switch# show port internal info interface fc8/3
fc8/3 is down (Error disabled - port down due to trustsec violation)
admin port-down trustsec-violation(3) num_times 0, duration = 0
Configuring Port Monitor
Port monitor helps to monitor the performance and the status of ports and generate alerts when problems
occur. You can configure the thresholds for various counters and trigger an event when the values cross
the threshold settings.

The port will be error-disabled due to bit errors if the port suffers link failure due to bit errors 5 times
in 120 seconds.
The port will be error-disabled due to credit loss if the port suffers link failure due to credit loss 5
times in 120 seconds.
The port will be error-disabled due to link down if the port suffers link failure due to bit errors 2
times and link-failure due to credit loss 3 times in 120 seconds.
