ARP responses - "neighbor scanning" - launch when do manual scan?

How does the neighbor scan work and can I force a scan like an IP scan? I have IPs on a network range outside of my Firewalls that must be populated by arp. I set neighbor scans up for once a day (probably not often enough).

Few questions...
does the neighbor "device" run a scan of the entire subnet when it runs its "neighbor" scan?
I have several IPs that are showing not responding and no mac, when in fact they are actively in the arp table of the device I've set up as neighbor.

thoughts?

No, you cannot force a neighbor scan like a subnet scan.

We are looking at the bridge MIB. The best way to troubleshoot this is to launch Switch Port Mapper from the Engineer's Toolset (you can download a free trial of it) and see what the device says. Also, if the devices are constantly showing in the ARP, you could just be getting bad timing, increasing the neighbor scan should help with this.
