Folks, I’ve been tearing my hair out trying to turn up a direct patch over single mode fiber using 10gig SFP+ between an MX-204 and a Nexus 7700. The MX can see the light from the 7700, and vice versa, but it never shows the interface as up. The Cisco eventually error disables the interface for flapping. Tried multiple SFPs, fibers, different ports, and the behavior is always the same. Auto negotiate on or off, speed/duplex hard coded, none of it works. Had zero issues with a different MX-204 talking to a Cisco 6832, so the issue seems to be Nexus specific.
Any hints appreciated. —Chris _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
