This video shows you the working logic of the Spanning Tree protocol on four Cisco Switches on Cisco Packet Tracer. ✅ S U B S C R I B E ► goo.gl/8d0iG9 ✅ Article ► www.sysnettechsolutions.com/en/spanning-tree-protocol-in-switching-understanding-stp-protocol/ To review the #Spanning #Tree #Protocol: Step 1: First, add 4 Cisco Switches to the PT workspace and cable them with GigabitEthernet interfaces. Step 2: Note the hardware MAC addresses of all the devices you added to the work area with the show version command in the CLI command prompt. Step 3: Also note the Priority values in the Bridge ID section of all devices with the show spanning-tree command in enable mode. Step 4: Under normal circumstances, when more than one switch is connected to each other for redundancy, a device in the network environment is automatically configured as a Root Bridge. However, when determining the root device, the following 3 basic values are calculated: 1) Cost 2) MAC Address + Priority 3) Lowest interface port Step 5: Since all devices in the network topology in our video tutorial are configured with gigabit ethernet interface, the cost value between each device will be 4. Therefore, because the cost values are equal, we switch to the other option. Step 6: Note the Designated, Root, and Blocked port status of all devices on the network environment. You can find these values in the Role section of the show spanning-tree command output. Step 7: The logic of the Blocked Port value is to prevent loops between devices in the network.
