Port fencing
Port fencing monitors ports for erratic behavior and disables a port if specified error conditions are
met. You can customize the thresholds and configure the ports to report errors for one or more
areas using the portThConfig command. After the ports are configured, you can enable port fencing
for specific areas of the physical ports, E_Ports, FOP_Ports, and FCU_Ports using the portFencing
command.

Active or online ports with errors that exceed the threshold are fenced after a six-second delay. In
cases where two types of errors occur within the six-second interval, the port is disabled and
indicates the reason code for the first error type that exceeded the threshold.
