Spanning Tree Loop Guard on Cisco Catalyst Switch
http://gns3vault.com Spanning Tree Loop Guard helps to prevent loops when you use fibre links. Fibre links have a transmit and receive connector. If one of these links fails it's possible that interfaces that are currently in "blocking" mode go to forwarding. This might cause a loop. Loop guard will ensure that if a blocked interface no longer receives BPDUs from the other side that it will be shut down to prevent a layer 2 loop.
