Grading Checklist

  • Used LLDP on the server to identify the actual connected switch and port
  • Compared LLDP output with the expected cabling plan
  • Identified the cable is physically in the wrong switch port
  • Verified the wrong port's VLAN (50/dev) vs. expected (320/prod)
  • Proposed moving the cable to the correct port (Eth1/33) as the fix
  • Recommended verifying the correct port is configured for VLAN 320 before moving the cable
  • Suggested releasing the DHCP lease on the dev VLAN before moving
  • Mentioned checking the cable label accuracy and updating if needed
  • Recommended auditing other servers from the same installation batch
  • Addressed the security concern of a production server being on the dev VLAN (even briefly)
  • Suggested implementing LLDP-based automated cabling verification as a process improvement
