Spanning Tree
The spanning tree protocol is used to eliminate loops in a local area network. A switch running this protocol
detects any loop in the network by exchanging information with one another and eliminates the possible loop by
blocking certain ports until the loop network is pruned into a loop-free tree, thereby avoiding infinite recycling of
packets in a loop network.

Hint§
The following parameters are shown on the Spanning Tree settings page:
■ Spanning Tree Status - Enable Spanning Tree on the switch. (Default: Disabled)
■ Force Version - Select the type of spanning tree used on this switch. Options: RSTP or STP, Default: RSTP
■ Priority - Bridge priority is used in selecting the root switch, root port, and designated port. The switch with
the highest priority becomes the STP root switch. However, if all switches have the same priority, the switch with
the lowest MAC address will then become the root switch. Note that lower numeric values indicate higher
priority. (Options: 0-61440, in steps of 4096; Default: 32768)
■ Maximum Age - The maximum time (in seconds) a switch can wait without receiving a configuration
message before attempting to reconfigure. All switch ports (except for designated ports) should receive
