When can we expect a bugfix for this 25G problem ?

- By definition you must forward the question to TAC. This group is only for customers , discussing experiences with bugs,

In our case I was able to configure the FEC on the Nexus side to " fec rs-ieee" or " fec rs-cons16" and the interface comes up and works. This info didn't come from TAC - I was just experimenting, but I do still have a case open to find out whether the Nexus or the WLC is at fault for the FEC autonegotiation issue and which of the two FEC modes they recommend.
