Do port IDs change for the same device in Libre?

[dt-lib]

Right now, my alerts are configured at the device level and for the specific port. I’m only monitoring specific uplink ports.

How can I create an alert or how should I create an alert to avoid using the port ID and use something that will never change/that I have more control over?

The thread I’m linking is how I’m currently creating a ‘port down’ alert.

Help with Alert for a specific port on a network switch

Hi, I have a network switch that I’d like to monitor a specific port. Alerts/Transports are working as I get an Alert when I unplug the switch from the network (test switch). I’d like to monitor a specific port (where I have a network printer attached). If this port is unplugged/goes down/etc I’d like to receive an alert. Navigating to the interface graph for the specific port (4) and showing the ‘rrd graph command’ I see that the port has an ID of 933. I’ve created a specific rule for this …

Then as I was reading about port IDs (which is what I’m currently using) I noticed that they can possibly change.

Thanks.
