For connecting multimode fiber how do we check Rx or Tx are properly working without breaking?

    For connecting multimode fiber there is some functionality available in cisco like UDLD and loopguard, what about on extreme switches?

    HI Alok

    you can use the below commands to see if there is RX or TX errors

    sh port rxerrors port-number
    sh port txerrors port-number

    for a specific port use like this
    sh port 1:2 txerrors
    sh port 1:2 rxerrors

    Hi Alok, Im no sure of this is the same as UDLD, but extreme has ELRP.
