Hi All,
Hoping anyone could answer this for me.
Just trying to connect a dell server to the C9500-48Y4C switch. Cable used from server to switch is Dell L56SF018-SD-R Cable DAC-SFP-3M. Usually I check the compatibility on the Optics Matric from CISCO; I could not find anything there. When it connect the cables to both the devices and after running sh int status on the switch I can see "err-disabled. " ALso tried the following :
Enable unsupported SFPs globally: (Did not work)
configure terminal
service unsupported-transceiver
--------------------------------------------------------------
Logs indicate the following :
debug platform pm all
sh loggging
Output is : Jan 2 07:45:48.541 UTC: %TRANSCEIVER-6-INSERTED: C1/0: iomd: transceiver module inserted in TwentyFiveGigE1/0/35
*Jan 2 07:45:48.669 UTC: %TRANSCEIVER-3-NOT_SUPPORTED: C1/0: iomd: Detected for transceiver module in TwentyFiveGigE1/0/35, module disabled
------------------------------------------------------------------
Tried FEC commands : (Did not work)
fec cl108
------------------------------------------------------------------
From the logs I can see the output clearly says Not supported. However, is there another way to make the cable work ? Perhaps a workaround ?
Version on switch : Version 17.9.3
Model Number : C9500-48Y4C
Any help is appreciated.
Thanks

- Use a DAC cable from https://tmgmatrix.cisco.com/?npid=50

So can we take this as conclusive proof that the Dell L56SF018-SD-R Cable DAC-SFP-3M is not compatible ?

After buying new cables from the compatibility matrix; connection is restored. Cable used SFP-H25G-CU3M. Thanks Marce1000.
