D-port tests failing

  • 1.  D-port tests failing

    Posted 07-14-2018 12:52 PM

    Hi All

     

    We have 4 x sanb48 switches , 2 at each site. each switch in each site, is belong to differnet fabric, and the member in the fabric is the remote switch (using ISL).

    Each switch has 2 Logical switches , each Logical switch has 1 ISL for the sites connectivity.

     

    The is new env, and also this is new DWDM infrastructure - so we want to see that all d-port tests are successfull.

     

    Fabric A - connect to ISL ports that are run on the same path (Lets call it MED1)

    Fabric B - connect to ISL ports that are run on the same path (Lets call it SHAHAM).

    Port 4 + 19 in each swtich are the isl ports (16G LW), and we see that we are only manage to pass d-port test only on 1 isl.

     

    2/4 tests are failed without any reason that i can understand.

     

    Please advise what could be the problem, we also try to swap the gbic/cables from Patch Panel, without any change.

    hello @yard

     

    first at all, you are here in the community, for that reason you should don't post here any Case Number.

     

    back to you main Topic, from output i see you have 4 Different FID, now is the question do you want to merge the Fabric's or is here any EX Port configured ?

    Hi

     

    This is streach env - means 2 san switch at each site , so total 4 SAN swtiches.
    2 Fabric's - Fabric A (DOWN) Fabric B (UP)
    Each Fabric has 2 Logical Swtiches : Private + Public.

    Some WDM gear requires the ports connected to that gear to be modified. What WDM gear are you running?

     

    When you setup the D-Port testing, did you specify the -dwdm option?

    Yes - we configue -dwdm.
