Often we need to put certain devices on specific VLANs. To do this, we need to know which port the device is connected to on the switch. However, in very mature and active wiring closets, it's quite a challenge tracing cable from the patch panel to the switch port.
We have found that by using the MAC tools on our switch (knowing the MAC address of the device), we were able to determine the port the device was attached to without having to physically trace the cable.

We had to move an HP Color LaserJet CP5225dn printer to a separate VLAN. The cabling in the wiring closet was so tangled we couldn't easily trace the cable from the patch panel to the switch.
