Trunk Missing a VLAN
One warehouse VLAN vanished across an inter-switch link while the other VLANs continued working.
Scénario
Norwood Maritime extended a warehouse VLAN to a second switch, and users on that floor can no longer reach the warehouse service. Other VLANs using the same inter-switch link continue to work, so the trunk itself is not simply down. Restore the affected VLAN across the link while keeping the existing segmentation intact.
