The Accounting VLAN Went Quiet After a Cable Audit
Accounting lost access to its file service after a cable audit, while a neighboring VLAN still works.
场景
After a cable audit at Queensgate Rail, the accounting VLAN stopped reaching its file service while a neighboring department is still online. The physical links and addressing look plausible. Compare interface state and reachability, then restore the affected segment without disturbing the other department.
