  • 1.  supported SFP+ comes up as unsupported?

    I have multiple JL255A (2930F) switches and a bunch of J9151E (10Gbps) transceivers.
    The AOS-Switch and AOS-CX Transceiver Guide (Edition 10) tell me this combo should be supported.  Unfortunately I can't get it working.

    Tested with 4 different JL255A switches and 4x J9151E.  Rebooted switches. Upgraded switches. Unplugged & re-plugged the SPF+.  Nothing seems to help.

    The following transceivers have extra information:

    Check: www.hp.com/rnd/device_help/2_inform for more info.

    That link in there
    Only thing the log gives is this:

    00371 FFI: ST1-CMDR: Port 2/27 self test failure ERR: 210907 15:05 00128000

    allow-unsupported-transceiver

    This command didn't help either.


    So, what is there to conclude from this?  With some luck that I am an idiot and missed something obvious? Please do tell! :)
    That I have 4 transceivers and/or 4 switches that are defunkt?
    That support for this combo is a printing error in the transceiver guide?

    Anybody got any ideas?

    Hi Koen, that's pretty strange since an original J9151E SFP+ LR Transceiver is supported on Aruba 2930F (for models having SFP+ ports) and the J9151E type replaced the corresponding J9151D type during 2019 IIRC so the E type is well mature.

    It would be interesting to see if there is a relationship with the fact that on adjacent ports (on 28 ports on both Aruba 2930F switches) there are already two SFP+ DACs J9281D (I think you can't simply test by removing all of them and test the J9151E alone since I presume you're dealing with a running VSF) or if the ArubaOS-Switch version running is somewhat older than the latest WC.16.10.0016 (having a recent ArubaOS-Switch build would be of help).

    What 4x4 part numbers (xxxx-xxxx) those J9151E have?

    4x4 part number is 1990-4727.
    Already upgraded the switch from WC.16.10.009 to WC.16.10.0016. Same result in both versions.
    And sure, Faulty SFP seemed logical until I tested a few more.  An entire batch faulty? Could be, but that doesn't help me know so I'll keep it for last. :)

    Yea.. waiting for support now

    Hey Koen,

    Did you get a response from TAC in the end?  I'm having the exact (or appears to be!) same issue on my 2930Fs when combined with J9151E's despite having this same combination working in other sites.

    Much like you upgrading from 16.10.0014 to 16.10.0016 had no impact and the same SFPs work fine in my 8325s.  I have a batch of over 100 of these so hoping that the result wasn't replace them all!

    Thanks,
    Matt.

    Sorry, nothing TAC could do, so they replaced all 14 SFPs. If you have 100.. good luck, TAC needed to create a new case for each and every one I needed to return.

    Should be plug and play i reckon, especially since the combo is supported. Return the SFP to sender?

    Get the latest firmware on the switch and try again. If it is really old, the E variant will not be recognised.

    However, the transceivers may be faulty - they are not reporting anything at all apart from "selftest err". You would normally expect to see something - this example from no-name 10G SR optic:
