Description

Follow up from T330479: Move WMCS servers out of eqiad row B.

        interface-mode trunk;
        vlan {

        }

                                                           ae3.0*

Now that there are no more cloud realm servers in prod row B, we can proceed with removing the two cloud vlans and the links between asw2-b-eqiad and cloudsw-c8/d5-eqiad

Mentioned in SAL (#wikimedia-operations) [2025-04-10T09:32:31Z] <topranks> decom 2x10G lag from cloudsw1-c8-eqiad to asw2-b-eqiad T391489

Indeed there is nothing there in row B on any of those vlans.

I've removed the config from the switches now so all that remains is for DC-Ops to remove the physicals on site and then delete the connections in Netbox:
