After further research Power Connect switches do not have an option or configuration to react to “known unicast” packets at this time.  Even the 7024 and 8024 have no mention of "known unicast".
Using a 5548 as my working example. I've enabled storm control at it's most sensitive level with: interface gigabitethernet1/0/1 storm-control broadcast enable storm-control broadcast level kbps 3500 storm-control include-multicast unknown-unicastYet initiating a packet flood, albeit unicast, doesn't trigger the protection.  Unfortunately this is exactly the case I am trying to protect against. Doing similar on a Cisco switch will allow protection to be triggered simply by traffic hitting a preset level - in the case I've set up, 90% of a port's potential bandwidth with: interface FastEthernet0/1 storm-control unicast level 90.00 50.00 storm-control action shutdown storm-control action trapIs there a way to implement similar protection on the Dell switch?
Storm control limit on unicast possible?
