arp-poisoning

someone can help me understanding arp spoofing prevention on dlink dgs-3100 (ftp://ftp2.dlink.com/PRODUCTS/DGS-3100-48P/REVA/DGS-3100-48P_MANUAL_3.60_EN.PDF).

I'd like to protect my gateway MAC/IP from spoofing so I'have tryed to add a rule "IP: 192.168.1.1 MAC: aa-aa-aa-aa-aa-aa" flagging all the port of the switch as untrusted. When I apply the rule I lose connection to all pc attached to the switch.

I certanly made some errors, but I can't understand what is wrong.

Best Regards

as seen on Stack Overflow - Search for 'Stack Overflow'
We have a database in which all the PKs are GUIDs, and most of the PKs are also the clustered index for the table. We know that this is bad (due to the random nature of GUIDs). So, it seems there are basically two options here (short of throwing out GUIDs as PKs altogether, which we cannot do (at… >>> More
