What eliminates switching loops?

  • Time to Live
  • VTP
  • hold-down timers
  • poison reverse
  • Spanning Tree Protocol

This is important at Layer 2 because there is no feature such as the Layer 3 TTL to stop data from traveling infinitely through the network. This helps keep switch MAC address tables stable in broadcast storms, and when multiple frames are sent.
