Spanning tree Protocol Aaron Balchunas 1. - Spanning tree Protocol - Switching Loops A Layer-2 switch belongs to only one broadcast domain, and will forward both broadcasts and multicasts out every port but the originating port. When a switching loop is introduced into the network, a destructive broadcast storm will develop within seconds. A storm occurs when broadcasts are endlessly forwarded through the loop. Eventually, the storm will choke off all other network traffic. Consider the following example: If HostA sends out a broadcast, SwitchD will forward the broadcast out all ports in the same VLAN, including the trunk ports connecting to SwitchB.
