Spanning Tree per Port
This administrative tool supports the
configuration of the Switch to forward, or
block and discard 802.1D spanning tree BPDU
packets.
Spanning tree is a bridge-based system for
providing fault tolerance on networks and can
be used to detect and disable network loops.
The spanning tree ensures that the optimal
path is maintained between spanning
tree-compliant networked devices by:
■Disabling redundant paths when the main
paths are operational.
■Enabling redundant paths if the main paths
fail.
Spanning tree uses a distributed algorithm to
select a bridging device that serves as the root
of the spanning tree network. The bridging
device known as the Root Bridge generates
BPDUs (Bridge Protocol Data Units) on all ports
at a regular interval known as the Hello Time.
All other spanning tree-compliant devices on
the network have a designated Root Port. This
is the Port nearest the Root Bridge and it is
