I have Juniper ex-2300 connecting to Cisco Nexus 5k by fiber. The problem is Juniper will show the link lights but cannot bring up the Cisco Switch showing the link down. They have matching SFPs. I have verified that I can bring up the Cisco switch with a lookback jumper. Has anyone seen this issue?

I will have to check that. I can get the same result with a test Cisco 2960-C.
