    Point 14.1 of the documentation says that arp monitoring does work in bladecenter (and even is the suggested solution). This is not true. When reading the sources, during arp monitoring each rx/tx counter increase is sufficient that the active slave stays alive. The arp monitoring is working well, as long as only one blade is attached to the bladecenter. As soon i add another blade to the bladecenter the failover does not work any more, because the rx/tx counter still increase with a unpluged wire from one switch. So the failover never can happen. The only way to fix this is to configure "Trunk Failover" on the bladecenter switch. This setting forwards the
    Link status directly to the card and use of normal dead link detection is possible and works well.
    Please update the documentation to not confuse more people, thanks.
