Might be interesting to know whose RJ45 SFP's? If third party I'd personally really tend to suspect/blame the third party...might be a coding issue, might be the onboard hardware doing something silly. I'd try a different vendor SFP. It might be something Juniper is making worse and is still willing to fix even if it's not necessarily their problem - like there've been various i2c reading issues they've dramatically improved behavior for. > > Yes, we're still having fun, > Richard > _______________________________________________ > juniper-nsp mailing list juniper-nsp@puck.nether.net > https://puck.nether.net/mailman/listinfo/juniper-nsp -- "Genius might be described as a supreme capacity for getting its possessors into trouble of all kinds." -- Samuel Butler _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
