Spanning Tree Protocol (802.1D)

  • STP basically used to in a network & provide loop free network.
  • STP is a layer 2 management protocol
  • A loop-free network is one in which no Layer2 loop exists therefore the network cannot create a layer 2 broadcast storms or flooded unicast storms.
  • The spanning tree algorithm (STA) runs on each switch to activate or block redundant links.
  • By default, STP is enabled on all the ports of a switch, if STP has been disabled, we can re-enabled it with the following global configuration command:

SWITCH (CONFIG) #SPANNING-TREE VLAN <VLAN-ID>
