Configure Spanning Tree Protocol
Description
The IEEE 802.1D Spanning Tree Protocol specification is designed to
prevent loops in a network by allowing only one active path between any
two network devices at a time.
Spanning Tree status: Enables or disables (press z) 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: Displays the number of times the spanning tree has
changed its configuration.
Time since last change: Displays 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: Display information used
by the root bridge in the same spanning tree as the switch.
Switch Priority: Determines 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).
