How do unset a /interface ethernet rule. I want the advertise statement gone, when i try to unset it asks for a number? but i dont want to remove number 2, just unset the advertisement config

Use winbox and set or unset whatever speed advertisements you need.

You can also use unset command in cli.

I want the advertise statement gone, when i try to unset it asks for a number? but i dont want to remove number 2, just unset the advertisement config

The way export command works is that it displays settings which are different than (current) default.

So what /interface ethernet export is saying in your case is that the advertised speeds for interface sfp-sfpplus2 is different than default (the rest of interfaces obviously have it set to defaults). Unseting whole advertise list (or setting it to empty value) won't make the line go away from export. You should rather set the list to default value.

I don't have CCR1072-1G-8S+ so I don't have a clue what might be default value. But you can get it by running command /interface ethernet print detail where default-name=sfp-sfpplus1 or by running command /interface ethernet export verbose (the later is like export but prints all settings, including the default ones). Then copy-paste the advertise= list from one of the rest of interfaces into command /interface ethernet set [ find default-name=sfp-sfpplus2 ] advertise=<list of speeds> ...

Yeah this worked like a charm thanks!
