Unable to change static ip address on 3 ports

I’ve managed to change one static ip address out of 4, when ever I try to change any of the other 3 network ports ip address’s I get an error. Any and all help much appreciated.

What part of that error isn’t clear to you? You’re trying to put a second interface on the same network, which isn’t a valid configuration. Either put it on its own network, or just don’t use it at all. See also:

Firstly, welcome to the forum!

The IP you’re trying to set on the interface ( is overlapping with another network already configured on another interface (

You can have multiple IP Addresses assigned to a single interface, but not multiple interfaces on the same network (without using LACP).

If you can describe your use-case we can certainly suggest a proper implementation.
