Intel 82599ES; GPON SFP module not working

Indeed only the x550 support N-Base and I think it's only N-BaseT. I don't have one to test with.

You can try setting the advertise speeds to 1G only in the negotiation:

[24.03-DEVELOPMENT][root@8200.stevew.lan]/root: sysctl -d dev.ix.0.advertise_speed
dev.ix.0.advertise_speed: 
Control advertised link speed using these flags:
	0x1 - advertise 100M
	0x2 - advertise 1G
	0x4 - advertise 10G
	0x8 - advertise 10M

	0x10  - advertise 2.5G
	0x20  - advertise 5G

	100M and 10M are only supported on certain adapters.

That still requires a compatible module though so may not allow it.

[2.7.2-RELEASE][admin@Gaia.home]/root: sysctl -d dev.ix.0.advertise_speed
dev.ix.0.advertise_speed:
Control advertised link speed using these flags:
	0x1 - advertise 100M
	0x2 - advertise 1G
	0x4 - advertise 10G
	0x8 - advertise 10M

	0x10  - advertise 2.5G
	0x20  - advertise 5G

	100M and 10M are only supported on certain adapters.

How do I set the flag?

Like:

[24.03-DEVELOPMENT][root@8200.stevew.lan]/root: sysctl dev.ix.2.advertise_speed=1
dev.ix.2.advertise_speed: 11 -> 1

But it has to have a device that supports those speeds. ix2 there is a combo port so it supports 1G, 100M, 10M baseT.

[2.7.2-RELEASE][admin@Gaia.home]/root: sysctl dev.ix.0.advertise_speed=1
dev.ix.0.advertise_speed: 0
sysctl: dev.ix.0.advertise_speed=1: Invalid argument

stephenw10

Mmm, it may not work. You would need to set it to 2 there though. 1 is 100M which is almost certainly not supported on that NIC.

milindhvijay

Any option would return invalid argument. I tried this a couple days ago.

stephenw10

Mmm, I suspected as much. That option depends on the NIC/module combination and it's not seeing anything as valid with that module present.

@milindhvijay any further fix or progress on this? I'm facing similar issue with my HSGQ/ODI XPON SFP ONU Stick, trying to connect to my pfsense router. Any help is appreciated. Thanks!

Details of the problem and the instructions to fix this is discussed here

That's a fun thread.
