RE: [Bugme-new] [Bug 3992] New: Bondig. Not correct work function ARP Monitoring. Broken link.

Our test lab has found a number of issues with ARP monitoring.  These bugs were on my to-do list for Q4 but got bumped due to other issues.  So now they're on my to-do list for Q1.

That being said, if somebody else really wants to fix this before I get to it, I won't complain.
