we have encountered broadcast storm on a GBE2c network.The 2 GBE2c blade switches in C7000 are running version 2.0 with PVST enabled for multiple vlans. Both switch are externally connected with Cisco switch with PVST enabled.

I suspect the STP on GBE2c is not working for some reasons.
Once we disabled one of the external trunk to Cisco switch , all become stable.

I want to find out if this a bug related issue with the f/w version.

I appreciate for any feedback. config is attached
Can anyone point me to any release notes to check this version out.

Please verify if you are using HP Network utility to team NICs.

I had a problem in an airport where i was deploying blades: i cloned an "already Teamed" machine and (since the "virtual" MAC generated the first time i team the NICs doesn't change during the clone) it began to Storm packets immediatley.

Since i disjoin the team on the 2nd machine, everything was normal again.
