Intel 82599ES; GPON SFP module not working

No, Hisense-Leox LXT-010S-H shows active and power(green) and activity(amber) indication light is constantly ON when optic is disconnected. With optic connected, lights come ON in constant intervals, stays ON for 2-3 seconds and turns OFF. Without optics I am able to get into the admin page and telnet works.

HSGQ-XPON-Stick shows no carrier with or without optic. Even the power/activity lights are off always. Never even seen (rxpause, txpause) in interfaces. If I remember right, it always stay on autoselect.

I think HSGQ-XPON-Stick does not work because it is a 2.5G stick and AFAIK Intel x520 supports only 1G and 10G. I've tried forcing it to 1G but no luck.

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?

stephenw10

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 hey did you figure this out?
having same issue, HSGQ-XPON-Stick shows no carrier, no lights.

milindhvijay

@bunneo Nope
