Most of this demonstration will be on the above Topology, except for the the output for changing Port cost, for that I'll just be using 2 Trunk links between SW1 and SW2. STP Link Speed to Path Cost, and how to change Path cost on an interface The link speed to STP cost … Continue reading STP – Path cost info, identifying the Root Bridge, Root Cost vs Path Cost, and debugging STP port state transitions!
Have had a minor surgery yesterday, Monday 10/9, and will be out for an undetermined amount of time during recovery from said minor surgery - Be back ASAP! ***Update 12/10/2017*** I have long since been back reviewing and updating my SWITCH articles, as I found a bit to be confusing after coming back, so I've … Continue reading Out Of Office after a minor surgery – Back to the grind ASAP!
This is an example of STP doing what it does best, and that is putting the Amber lit port 2 in "Blocking" state, to prevent a Switching Loop from forming. This is the logical Topology for a better idea of what's plugged into what: This post is focused on the "original" STP, all the fundamentals … Continue reading STP – Spanning-Tree Protocol Fundamentals, Root Bridge Election, BIDs and BPDUs, STP Port Roles / States!
