> # 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 default port monitor policy has the following threshold values:

> Counter | Threshold Type | Interval (Seconds) | % Rising Threshold | Event | % Falling Threshold | Event
> --- | --- | --- | --- | --- | --- | ---
> Link Loss | Delta | 60 | 5 | 4 | 1 | 4
> Sync Loss | Delta | 60 | 5 | 4 | 1 | 4
> Protocol Error | Delta | 60 | 1 | 4 | 0 | 4
> Signal Loss | Delta | 60 | 5 | 4 | 1 | 4
> Invalid Words | Delta | 60 | 1 | 4 | 0 | 4
> Invalid CRCs | Delta | 60 | 5 | 4 | 1 | 4
> RX Performance | Delta | 60 | 2147483648 | 4 | 524288000 | 4
> TX Performance | Delta | 60 | 2147483648 | 4 | 524288000 | 4
