We're currently having problems with Cisco DAC's (5m) active cables that only shows up as "ge" ports in our EX4500-VC and won't come online (Intel 10G NIC in the other end, works fine with Dell-switches/modules). We're running 11.3R4.2, I've heard some unofficial rumors about this version and earlier that won't "take" 3rd party sfp+, we have a couple of juniper DAC's and a couple of 3rd party sfp+ (coded as Juniper) that works fine though. To be honest we're not running any Juniper SFP/XFP/SFP+ transceivers and it has worked great for us so far, it's just the Cisco active ones that won't come up. If I have time I will upgrade to the latest recommended software or just go with the 3rd party vendor and run fiber-cables instead. -- Timh Bergström Head of System Operations Videoplaza/System Operations timh.bergst...@videoplaza.com +46 727 406 845 S:t Eriksgatan 46 Stockholm www.videoplaza.com skype: timh_bergstrom gtalk: timh.bergst...@videoplaza.com linkedin: _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
