Unfortunately SR/MMF transceivers have no DOM support. We'll definitely get some fiber power meter tests ran during "the problem" time @ 850nm
Physical inspection has been completed already as well. No obvious places where there would be any sort of environmental impact and no current signs of distress/damage to the fibers. Fiber ends have been cleaned thoroughly. ________________________________________ From: [email protected] [[email protected]] on behalf of Michele Bergonzoni [[email protected]] Sent: Wednesday, April 03, 2013 2:29 AM To: [email protected] Subject: Re: [c-nsp] 10gig Link Bouncing Consistently > Beginning several days ago both links began flapping every 5 and a half > hours, both links have this happen within a couple of minutes of each > other. > They will flap for several minutes and then return to normal operation > requiring no user action and the ports never enter err-disable or show > any other symptoms. Your story popped me up a distant memory of a heating system that happened to leak steam on a fiber cable. That cable contained all the 4 fibers of a presumed redundant connection. I would not let the next predicted flapping time pass without: * "show interface transc det" when everything works, and when things go bad * technicians at both ends ready to disconnect one line and test the loss on the fibers with appropriate instruments, in the first window (~850 nm) * physical inspection of the fiber run, if feasible If the fibers turn out to be OK, when you have a Cisco 6509 on one end and a Netgear on the other, and you need to try to replace one of them, we all know where to start.
