dubious broadcast traffic on SGE2010

Hi community members,

I've localized a (for me) strange situation on servers connected to a SGE-2010 48 port switch.

Creating a tcpdump on one of the machines I can see IP traffic (not to the server which creates the dump) of other machines connected to the switch. There are 36  servers connected to the switch and the switch is connected to a part of our infrastructure with approximate 350 servers.

It seems to act as a hub. I cannot find a menu-topic to show the count of the entries in the MAC-table which could indicate this behavior.

Does anybody have an idea what can cause this behavior or how to troubleshot this.

Thanks.
