    I have 2 Brocade B300 connected with optical Fiber OM2 50/125 LC/LC ( so the port is an E_port).

    I try to change this fiber because it's too short.


    I have try one OM3 fiber, result :  no connection

    I have try an other OM2  fiber longer : no connection 


    But if i reuse the old fiber : it s ok ! 


    I don't understand why ....


    Do you have an idea ? 


    Best regards

    That is a strange problem. On the surface it would seem the new cables are faulty.    As a test, I would try the OM3 cable again

    and check the physical layer and port log:


    a) disable the ISL ports at each end

    b) insert the OM3 cable

    c) clear the fc and asic counters:    statsclear;slotstatsclear

    d) enable the ISL ports

    e) check the port error counters:  porterrshow, portstatsshow

    f) check the portlog file:   portlogdump -i



    Also check the cable sheathing info to confirm the fc cable is what you believe it is.
