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: Use the z to 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 will be turned on
automatically by the switch.)
Topology changes: The number of times the spanning tree has changed
its configuration.
Time since 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: Accepts 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).
Hello time: Accepts a number from 1 to 10 seconds (default is 2
seconds). This is the time between transmissions of configuration
BPDUs (Bridge Protocol Data Units) when the switch is, or is attempting
to become, the root in the spanning tree.
