Since a few days/weeks (after upgrade to OA firmware 4.30 it seems ?) we receive the following messages in our Onboard Administrator loggings:

Network flood in your network. Mostly broadcast storms. Packets are detected and discard by the OA.

Please check your network enviorment and make smaller subnets / vlans.

Hi

Try to have a seperate vlan for management as recommended by HP.

Thankx
