Spanning Tree Protocol Configuration
Spanning tree is a link management protocol that provides path redundancy while preventing
undesirable loops in the network. For Layer 2 Ethernet network to function properly, only one
active path must exist between two stations. The spanning-tree algorithm calculates the best
loop-free path throughout a switched network. STP forces redundant data paths into a
standby (blocked) state. If a network segment in the spanning tree fails and a redundant path
exists, the STP algorithm recalculates the spanning tree topology and activates the standby
path.
The unit provides a switch level menu and a port level menu.

If you enable the spanning tree protocol, you must complete the Bridge Priority and Time
fields with appropriate value.
