Network Engineering Asked by devilfox on January 7, 2021
I have bought a Netronome Agilio CX smartNIC which has QSFP interface. My switch HP 3500yl J8593A has 4xSFP+ interfaces. I bought Amphenol QSFP to 4xSFP+ breakout DAC. But the switch complained about "Not HP transceiver". How to get around this issue? I tried to configure the switch to allow 3rd party transceiver but unfortunately, this specific switch doesn’t have this feature. Any suggestions on how to get things working would be of great help to me.
Thanks
HPE switches only accept HPE-branded transceivers (of the right series) by default.
If there's a quite recent firmware version for the 3500yl (16.02 or newer), you could use (config) allow-unsupported-tranceiver to make the switch accept non-HPE transceivers/DACs. Then replug the DAC to make it accepted.
If not (it seems the last firmware is 15.04.003), you'll need to buy a HPE-compatible breakout cable (the 3500yl accepts J928xB and J930xA series DACs) - various vendors offer 100% compatible, usually much cheaper variants. Make sure you don't have the same problem with the NIC, but most NICs accept generic MSA DACs.
Alternatively, forget about DACs and use 10GBASE-SR transceivers (J9150A for the 3500) with multi-mode fiber.
