I just put some QSFP28 BiDi (JQ344A) transceivers in my 5945 switches (JQ074A, R6555). I get no link (Line protocol state: DOWN). Neither switch-to-switch nor switch-to-server works.
I suspect some kind of issue with the autonegotiation. The manual however says, that a connection between HGE ports of two JQ074A should work with default settings.
Anyone can tell me what I'm missing?
