[j-nsp] input errors on QFX5110

[james list]

Dear experts,
a customer of mine has a Fiber Channel over IP switch connected to a port
QFX5110 port and sees a lot of "Input errors" and "oversize frames"

Input errors:     Errors: 118467
Oversized frames                    118467

below extensive output


Are those counters related to frames dropped or just a counter ?

The same machine connected to a previous QFX5100 (different Junos) does not
highlight the same counter.

Since the FCoIP switch manager sees packet loss and retransmissions and
states no jumbo frame should be needed, which is your idea of the issue ?

I see as well this:

 Autonegotiation information:
    Negotiation status: Incomplete

Thanks in advance
James
