Hi Mohammed,

>From the command you ran you should see the bridge ID for the switch you
are connected to and that of the root bridge. Don't forget that this may be
the same switch. If it is not, look at the root port and work your way
through the switched network. If nothing else you will also know what your
topology really looks like and also work out which switch will become root
if you lose the current root bridge, along with how this would change the
topology.

HTH,
Graham
