Explanation
As CDP has different information for Switch1 it is obvious that there is a cabling issue Verifying Layer 2 Connectivity Verifying Layer 2 connectivity involves checking switch ports and each connected device at an Ethernet level, ensuring Layer 2 connectivity has been established and also checking errors for a connection. Although all indications might be that a Layer 2 connection is operational, it is also good to actually confirm that Layer 2 traffic is being sent and received between two devices. Cisco Discovery Protocol (CDP) provides such functionality, verifying connectivity to locally connected Cisco devices. Checking Network Cabling Many physical layer connectivity problems are caused by faulty network cabling. All cabling between your switch and the rest of the network should be thoroughly tested prior to implementation using a professional cable tester. Ensure that you always use compatible cables for the protocol you are using. A common source of cabling issue is the incorrect use of straight-thru and crossover RJ-45 cables. Any device to-switch connection should use a straight-thru RJ-45 cable, while any device- to-device or switch-to-switch connection requires the use of a crossover RJ-45 cable.
