https://community.hpe.com/t5/bladesystem-general/gbe2c/m-p/4788054#M13574 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.<BR /><BR />I suspect the STP on GBE2c is not working for some reasons.<BR />Once we disabled one of the external trunk to Cisco switch , all become stable.<BR /><BR />I want to find out if this a bug related issue with the f/w version.<BR /><BR />I appreciate for any feedback. config is attached <BR />Can anyone point me to any release notes to check this version out.
