Re: [j-nsp] EX4500 - 3rd party DAC/Twinax cable support - link-up at 1g instead of 10g
Hi all, Just following up on this post from April. My customer followed through with JTAC and eventually it was determined that, while active DAC cable support was planned for introduction in JUNOS 12.1, it didn't actually make it. References to active DAC cable support disappeared from various documents in late May (12.1 release notes, etc.) JTAC said: The Active DACs that are coming for EX's will be first supported on the EX8200's and could be coming next release. cheers, Dale On Sun, Apr 29, 2012 at 12:43 PM, Dale Shaw dale.shaw+j-...@gmail.com wrote: Hi all, I have a customer that is trying to connect some ESX hosts at 10g to a recently commissioned EX4500 VC.

Hi, I bought a couple of 3rd party 5m active cables (that were supposed to be coded for Juniper EX) that showed up as ge-* interfaces. We were connecting them to a pair of Cisco Nexus 5010s, which detected them correctly. We noticed that some 3m «official» Cisco cables we had lying around worked fine, so we asked the cable provider to copy the EEPROM ID (or whatever it is called) from one of those onto the 3rd party ones, and that made them work fine. It shows up in show chassis hardware like this: Xcvr 11 NON-JNPR F111026008SFP+-10G-CU3M And show chassis pic fpc-slot 0 pic-slot 0: 1110GBASE CU 3M n/a CISCO-TYCO 2053783-2 n/a This is a EX4500 VC running 11.1R3.5, the cables are plugged into the built-in ports. Everything runs great now.

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
