I have no cure, but I have been seeing similar issues with one of my PowerRouter 732s which I believe is the same hardware. The UPS between it and the grid is not terribly great. It is ancient and pre-dates our use of the site. I believe I only see this problem when a power event happens. One of the ports will start flapping at about the frequency you mention. This is always when a storm has come through the area, 50 miles from me. A reboot of the PR732 sorts it out immediately. I think the power browns out during the transition and something comes unglued in the ethernet device. The PR732 runs fine on the UPS after a reboot. I don't know if it's a driver issue or a hardware issue. I originally installed the PR732 running RouterOS 5.x with a small but new UPS. The UPS died and the person on-site plugged us into his UPS. Some time after that is when we started noticing these problems. I cannot remember if we had upgraded to RouterOS 6.x before the UPS died or after. -- Scott Lambert KC5MLE Unix SysAdmin [email protected] http://cqnewsroom.blogspot.com/2013/03/just-like-twitter-only-more-advanced.html _______________________________________________ Mikrotik mailing list [email protected] http://mail.butchevans.com/mailman/listinfo/mikrotik Visit http://blog.butchevans.com/ for tutorials related to Mikrotik RouterOS
