a switching loop in the networkcausesbroadcast storms

a nice network loopcreatinga broadcast storm

UTC A network loopwould causea broadcast storm

This will cause a loop in the network -causinga broadcast storm

a loop or some other network problem(passive) caused bya broadcast storm

loops in your network a switching loop(passive) caused bybroadcast storms

This may lead to a loop on the networkcausingbroadcast storms

If so , do you have a bridging loop somewherecausinga broadcast storm

Therefore , it was not loopcausedbroadcast storm
