Lock Down IP-MAC-Physical Interface Binding on ASA 5505?

Unanswered Question
Apr 18th, 2009

Hi,

Is it possible to lock down an IP-MAC-Physical Interface binding similar to using port security or IP source guard on the physical ports of the ASA 5505? This is to prevent spoofing, man in the middle attacks and the connection of unauthorised devices on physical interfaces that will be patched to publicly accessible wall jacks.

I have tried making static MAC entries however this does not seem to be supported on the ASA 5505. I have also looked into the IP spoofing feature however this seems to be more for spoofing between VLANs (zones) than per physical interface.

Any suggestions will be greatly appreciated.

Cheers

I have this problem too.

IP-MAC mappings are possible in transparent mode but not in routed mode.

You might have move mac-ip bindings to your switches I suppose
