Spanning tree protocol is an essential function of Ethernet networks, and it provides several useful capabilities when used properly. However, STP can cause havoc when a network carrying live video is ...

While the history of Internet development involves many names and was not reliant on a single discovery, it is also true that certain innovations have done more to enable better networks for all. It ...

Those who had an opinion last week were split evenly: CCNA labs need either 2 or 3 switches, and CCNP labs need either 3 or 4. But why? We saw a few opinions floating around the blog last week, but ...

I am amazed by the number of networks that I encounter that do not have optimal spanning tree configurations. I first read Radia Perlman’s book “Interconnections” back in 1994. I am amazed that 15 ...

Is the Spanning Tree Protocol a thing that is always operating in managed and unmanaged switches? (Even your basic SOHO Linksys or Netgear switch.) ...

Thanks for STP. but one thing pops in my mind how does it stops a network loop in this scenario. A frame (source pc0/1, destination pc2/1) just entered my Switch(SW1) and then router(R1) then ...

An algorithm that runs in network bridges and switches to prevent loops, in which packets keep going around in circles. In a small network with one or two switches, the spanning tree protocol (STP) ...
