DAI inspection - Rate limit

Unanswered Question
Apr 8th, 2010

Hey All,

I've implemented layer 2 security for DAI and DHCP snooping etc

I've set the the following interface command for packets per second.

"ip arp inspection limit rate 100"

But I noticed printers go over the 100 now and then, and the port goes into err-disable.

So questions,

Is 100 a appropriate value? I've never had any user ports have issues as of yet.

Is there a way to make limit rate unlimited for specified mac addresses? as the printers can move around.

Many Thanks,

Alan

I have this problem too.

thanks, i've already read through the guide and know the default values.

Raising to a larger value, does make it work. But I was just wondering if there is a way to set up a access list or something, so it still works when the printer moves to a new port..?

i.e there is a arp access-list for devices with static IPs.

Maybe this is not possible.
