This is the blog of Ronald Bartels that wanders on and off the subject of problem management (that is how it started), but it is best described by Ray who says this is Daddy's thoughts! Like the best music is from the Eighties and a wee dram helps in solving most inconveniences.
Network Rookies Leave Spanning Tree At Defaults
Network rookies leave spanning tree at defaults. The root bridge ends
up as some switch in a closet. A new switch is added to the network,
and sometimes traffic goes wonky for a while. Spanning tree gets blamed
as if it’s a teenager with an attitude problem. Wrong. Spanning
tree just needs to be managed, and then it behaves predictably. It all
starts by rigging the election to make the root bridge the switch you
want it to be.
