Displaying transceiver properties

Hello all,

Is there an east way how to display transceiver properties like the inserted type? So far I have tried through clish show interface ..,

[Expert@gw-4370e6:0]# ethtool eth3-01
Settings for eth3-01:
        Supported ports: [ FIBRE ]
        Supported link modes:   40000baseKR4/Full
        Supports auto-negotiation: No
        Advertised link modes:  40000baseKR4/Full
        Advertised auto-negotiation: No
        Speed: Unknown!
        Duplex: Unknown! (255)
        Port: FIBRE
        PHYAD: 0
        Transceiver: internal
        Auto-negotiation: off
        Link detected: no

Above, I am not sure whether the transceiver was even installed, in case of this 2-port 40G card, shouldn't it described it as external instead of internal? I have tried ethtool -m eth3-01, or ethtool -e but it seems these option are not supported in Gaia.

Re: Displaying transceiver properties

Try "ethtool -i (interfacename)", that will show the driver type.  Here is a quick mapping of driver to manufacturer from the upcoming second edition of Max Power:

e1000, e1000e, igb, ixgbe, w83627


Recommended with latest GA jumbo hotfix loaded

mlx5_core, mlx_compat


Relatively new 40Gbit fiber card for 15000/23000 appliance series only

Obsolete very bad

Intel is always preferred, Mellanox seems to be OK so far but the jury is still out for now...

Re: Displaying transceiver properties

Thanks for the tip with -i flag, but what I was referring to is output like inserted transceiver type e.g. CPAC-TR-40SR-QSFP-300m, its serial number and so on.

hi Maros, did you ever work out if there is a way to get this output?

Re: Displaying transceiver properties

Hi there,

I opened case for this question around a year ago and the official answer was:

"There is no way to gather such information from CLI".


I was able to found some info by shutting down affected interface and bring it up again.





Cant remember exact info there was, but for sure there was no serial number.

I hope (dont believe) that there will be something like "show interface transceiver" in R80.30 ....

Kind regards,
