I have an ICX 7850 (08.0.95g) as my distributed core. I can connect 7250s just fine, but I cannot link 7150s (08.0.95g). I've tried the connection with both multimode and single mode. The sfp modules match, the speed-duplex matches, the vlan's match. The media is validated on both ports. Any ideas here?
Ah, well then that would make sense. Thanks so much for the assistance. This worked on my test environment, now I can try it on my production switches.
Out of curiosity: I see in the documentation that "When Gbps negotiation mode is turned off (using the gig-default neg-off command), the device may inadvertently take down both ends of a link. This is a hardware limitation for which there is currently no workaround."
No problem at all. I think that is a warning if your link is already up this command could bring it down as you are disrupting any prior negotiation. You could also see a flip at initial configuration, but it will come up if configured properly.
