212160-B
With the BPS 2000 with software version 1.2, you can configure multiple
spanning tree groups (STGs). (Multiple spanning tree groups are available only
when the Stack Operational Mode is set to Pure BPS 2000 Stack.) The CLI allows
you to configure spanning tree groups, to add or remove VLANs to the spanning
tree groups, and to configure the usual spanning tree parameters and FastLearn.

show spanning-tree command
The show spanning-tree command displays spanning tree configuration
information that is specific to either the spanning tree group or to the port. The
syntax for the
show spanning-tree command is:
show spanning-tree [stp <1-8>] {config|port}
The show spanning-tree command is in the privExec command mode,
Note: When you omit the spanning tree group parameter (stp <1-8>) in
the any of the spanning tree commands, the commands operate on the
default spanning tree group (spanning tree group 1).
