Spanning Tree
The Spanning Tree function can be used to prevent network loops and to provide backup links with another
network device. It can ensure that only one route exists between any two stations on the network.
Note
: Whenever any network connection configuration is changed, the new connection will start to work after
about 30 seconds if spanning tree is enabled. Thirty seconds is the spanning tree re-configuration time.
