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 ...

Spanning Tree Protocol is the tried and tested method for providing path redundancy while eliminating loops in bridged networks. Spanning Tree Protocol, supported on most bridges and switches, is the ...

On a small network (<250 users) I had a user buy a 5-port Linksys switch and uplink (via 2 cables) to Ethernet ports on the wall. This caused an infinite loop that caused some problems for the site, ...

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 ...

Dr. Alexander Pasik, Chief Information Officer, IEEE, interviews Radia Perlman, IEEE Fellow and inventor of the Spanning Tree Protocol You are an IEEE Fellow and well-known to anyone in the networking ...

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) ...

On the network on which I work, the spanning tree protocol hello time is set to 2 seconds. After doing a few sniff sessions in some of the different vlans, i'm beginning to wonder if this setting is ...
