How to get spanning tree port state with SNMP (HP Procurve 2650) ?

Hi,

Is there anyone who knows how to get the spanning port state on a HP
Procurve 2650.

I'm using 12 switch HP 2650 on my lan with RSTP protocol activated. I'd
like to know in real time which port on which switch is in
blocking/forwarding state...

If someone knows the good OID, it interrests me !

Is there a good network tool to draw a graphical network layer 2
topology with spanning tree information ? I've tried LoriotPro but it
seems to not work with RSTP protocol. Do you know another ?

Thanks in advance for your help.

Finalement, j'ai fini par trouver. Pour ceux que ça intéresse :

..1.3.6.1.2.1.17.2.15.1.3
..iso.org.dod.internet.mgmt.mib-2.dot1dBridge.dot1dStp.dot1dStpPortTable.dot1dStpPortEntry.dot1dStpPortState

Testé sur Switch HP2650

1 = disabled (rien n'est connecté au port du switch)
5 = forwarding (le port fonctionne normalement et laisse passer le
traffic)
2 = blocking (le port est bloqué suite à la négociation spanning
tree pour éviter une boucle)
