Configure Spanning Tree Protocol
Description
The IEEE 802.1D Spanning Tree Protocol specification prevents 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 is turned on automatically by the switch.)
Topology changes: Displays the number of times the spanning tree has
changed its configuration.
Time since 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).
