AFAIK, Dynamic ARP Inspection is not supported on the Catalyst 2960.

[edit] i've double checked and it is only supported on the Catalyst 6500/4500/3550/3560/3750, please use the feature navigator for checking.

Is there a way or a work around that I can try to stop ARP poisoning at switch level. I tried enabling port security but without any luck. Any help in this regard is greatly appreciated

Thanks in Advance

Release Notes for the Catalyst 3750, 3560, 2970, and 2960 Switches, Cisco IOS Release 12.2(40)SE have, in table 7:

Dynamic ARP inspection (IP services image [formerly known as the EMI] only)


3750 and 3560

If you have the IP service image, you could try the commands listed in: http://www.cisco.com/en/US/products/hw/switches/ps5528/products_configuration_guide_chapter09186a00808a9951.html
