Hello everyone
Few days ago we had a planned change in our network to add a new backup link and add it to the BGP process on the router . but on doing that , the engineer decided to use an old port that was configured for VLAN 14 but wasn't being used , while , the VLAN itself , is trunked on this router through another switch and then goes out the main uplink to the rest of the network .
the problem is , once the guy deleted the config over this port ( including the part linking it to vlan14 ) , the main vlan 14 interfaces was also deleted !!
Anyone knows why did this happen ? is it a bug or something ?
