CRS125-24G-1S-2HnD-IN upgrade problems

Hi,

On a CRS125-24G-1S-2HnD-IN that had firmaware version 6.5 from 2013… I clicked on firmware upgrade in winbox…
After rebooting! Everything went south, near desaster… Nothing work from the old config. Vlan- bonding- trunk- dhcp client and server…

So After logging in with the mac adress with a computer plug directly on port ether2, I restored the config backup I made before upgrading.

Now it look like the config came back partly but I feel like I’m missing features.

Like in the interface > genereal the master port is not there anymore!

Can anybody has an idea of where the master port option is now ?

thanks
