CRS354-48G-4S+2Q+ and Q+BC0003-S+ Cable

Hi All,

Hoping you can help - new to this switch and I am currently using the Q+BC0003-S+ breakout cable to connect 2x ESXi Hosts at the moment..

Regarding interface qsfpplus1-1 plugged into host ,1If I set this to auto negotiate it will never come up - if I tell it to use 10Gbps FD then the connection establishes and the first ‘triangle’ light illuminates on the switch.

Regarding qsfpplus1-2 plugged into host 2, auto negotiate works fine - same cards - why the differences ? If I remove qsfpplus1-1 then the triangular light does not illuminate at all - does this need the ‘first’ cable always in to light ?

Additionally, the individual rectangular link activity lights do not illuminate - why not ? Is there a config I need to make for this ? It is all default at the moment other than the changes mentioned above.

Running OS 6.47.2

Thanks.

Anyone able to shed any light on this one ?

Thanks.
