RouterOS Dynamic ARP Timeout Setting?

RouterOS General
1

Is there a setting to modify how quickly a Dynamic ARP entry times out in RouterOS?

The documentation wasn’t much help on this issue, nor was google.

You can’t “manually” create a dynamic ARP entry, so the timeout really depends on whatever other command caused the ARP entry to appear. Typically, the ARP entry will disappear as soon as the other command is no longer in effect. For example, if it’s an ARP entry for a DHCP lease, it will be removed as soon as the lease expires.

I need the entry to drop out of the arp table all together after a few minutes of inactivity. We have a specific IP address that is used by field techs when they are working at a tower. The problem is that from one day to the next, these dynamic arp entries don't seem to be going away so when a new field tech gets there the next day, we have to remove that dynamic arp entry so a different device/mac address can talk on that IP. Hope that makes a little more sense. Thanks,

Probably ‘ARP-timeout’ property is what you are looking for.

HTH,

I believe that's what I am looking for! Thanks for your help!
