LACP with existing IP adress

[tsr966]

My freenas main IP adress I set up is 192.168.1.102 I recently bought a managed switch, Unifi 48. I would like to combine the 4 ports I have on my Dell R720XD. Can i just create a link aggregation in freenas for the 4 ports and use the original IP address without any problem?

You have to remove the IP address from the interface that you are currently using, create the new link aggregation, then add the IP to the new interface.

From the IP networking point of view, the link aggregation is a different interface onto the same network. It happens to be a virtual interface, but the IP stack doesn't care about that.

People get all confused about this stuff. Keep it simple in your head. The physical interfaces are consumed by the link aggregation and effectively "cease to be" as a separate networking consideration.

Yes. Use the console UI, that's what it is for.

After I use the console to set up the lag can I change the ip to the original address?
