/interface ethernet set [ find default-name=ether1 ] speed=100Mbps

I’ve got a CRS125 which has always from new (as far as I can remember) had this in the configuration:

/interface ethernet set [ find default-name=ether1 ] speed=100Mbps
/interface ethernet set [ find default-name=ether2 ] speed=100Mbps
/interface ethernet set [ find default-name=ether3 ] speed=100Mbps
/interface ethernet set [ find default-name=ether4 ] speed=100Mbps
/interface ethernet set [ find default-name=ether5 ] speed=100Mbps
/interface ethernet set [ find default-name=ether6 ] speed=100Mbps
/interface ethernet set [ find default-name=ether7 ] speed=100Mbps
/interface ethernet set [ find default-name=ether8 ] speed=100Mbps
/interface ethernet set [ find default-name=ether9 ] speed=100Mbps
/interface ethernet set [ find default-name=ether10 ] speed=100Mbps
/interface ethernet set [ find default-name=ether11 ] speed=100Mbps
/interface ethernet set [ find default-name=ether12 ] speed=100Mbps
/interface ethernet set [ find default-name=ether13 ] speed=100Mbps
/interface ethernet set [ find default-name=ether14 ] speed=100Mbps
/interface ethernet set [ find default-name=ether15 ] speed=100Mbps
/interface ethernet set [ find default-name=ether16 ] speed=100Mbps
/interface ethernet set [ find default-name=ether17 ] speed=100Mbps
/interface ethernet set [ find default-name=ether18 ] speed=100Mbps
/interface ethernet set [ find default-name=ether19 ] speed=100Mbps
/interface ethernet set [ find default-name=ether20 ] speed=100Mbps
/interface ethernet set [ find default-name=ether21 ] speed=100Mbps
/interface ethernet set [ find default-name=ether22 ] speed=100Mbps
/interface ethernet set [ find default-name=ether23 ] speed=100Mbps
/interface ethernet set [ find default-name=ether24 ] speed=100Mbps

I don’t think it’s actually setting the speed to 100Mbps - the ports all seem to be running at 1G.

I’ve just got a CRS112 and it does not have those lines in its configuration.

Should I remove them from the CRS125, and if so how do I remove them?

Thanks.

At some point the default values which are supressed during /export were changed, so any existing configurations after a firmware update exhibit this. If you reset the configuration back to factory with the newer firmware the newer defaults are used. I’m not sure why it was changed as only 10-Half, 10-Full, 100-Half, 100-Full are the only permitted non-negotiated speeds on copper interfaces.

The speed= setting is only utilised when auto-negotiation=no so it is purely cosmetic. You can update the setting with
/interface ethernet set [ find default-name=ether1 ] speed=1Gbps

Perfect - thank you.
I did that for all 24 ports and now my / export terse is much more terse :slight_smile:

Out on interest, is there a way simple way to view the default values?

Thanks.

There is /system default-configuration print which displays the commands applied to create the default setup from a factory reset state, however AFAIK there is nothing to show the initial configuration other than not to apply the default setup and then use /export verbose

Nice - thank you!
