• 2. Set Switch-M24PWR.
  • 1) Enable the STP global setting.
  • 2) Enable the BPDU guard function.
• 3) Connect the loop and confirm that the port shuts down.

Setting Procedure

Step 1. Connect to the Web management screen of Switch-M24PWR and login.

Connect the PC and Ethernet Switch using a twisted pair cable, and connect to the Web management screen of Switch-M24PWR.
