I need to see if there is a way to setup dynamic arp inspection on a cisco 2811 router. We are currently using arpwatch, however we are going to have cisco routers in all of our branches and cisco switches in some, and we will not be able to monitor everything from one broadcast domain as we have in the past. I know we are able to set it up on the 2960 swithces that we have, but need to know if the routers support this feature for the other offices. I have researched this topic, and I can't any documentation on the 2800 series routers supporting this feature.
We have looked for windows alternatives, however we need a way to monitor the activity via email alerts.
Are there any other viable options that anyone can suggest?
