Spanning Tree Protocol

Description

The IEEE 802.1D Spanning Tree Protocol specification is prevents loops in a network by allowing only one active path between any two network devices at a time.

Spanning Tree status: Use the zto enable or disable support for the Spanning Tree Protocol, where the entire switch is a bridge for which you can set spanning tree parameters. (Note: If you are running 802.1Q VLANs, spanning tree must be enabled and is turned on automatically by the switch.)

Topology changes: The number of times the spanning tree has changed its configuration.

Time since last change: The elapsed time (since the last switch reboot) since the spanning tree last changed its topology (the paths used to get through the network).

Root MAC address, Root path cost, Root port: Information used by the root bridge in the same spanning tree as the switch.

Switch Priority: Type a number from 0 to 65535 (default is 32768). The device with the lowest number becomes the root device (starting point for the spanning tree).
