Switch port Speed Limit summary

excessive traffic and loss of network performance. Errors in the protocol stack or errors on the network configuration can cause storms. Storm control (or flow suppression) manages the flow state of the stack, and is managed through a time and contrast measurement with pre-set threshold values for the suppression level. The threshold value is expressed as a percentage of the total available bandwidth for that port. The
