Pen name is also large, the motto of the game

Today it is the command of the Cisco switch which is the practice of the work operation, I feel that sometimes it may be necessary to trace the port of which the MAC address belongs to the switching device, and to determine the object quickly, I share my exercise to the lovers who need it.

The first thing you need to know is the IP address and account password of the core switch device of your organization.
