Is it still advised on pfSense v2.6 to add the following to the (System) Tunables:
dev.igb.0.eee_disabled=1
dev.igb.1.eee_disabled=1
dev.igb.2.eee_disabled=1
dev.igb.3.eee_disabled=1I'm using a 4 port igb NIC.
Is this still needed or is it obsolete now?
-
No, you should not need to do that. We don't set that on anything we ship with igb ports.
That OID is now obsolete replaced by
dev.igb.X.eee_controland that is set to 1 by default.Steve

@stephenw10 Thanks!
eee_control can not be found in system tunables, is that correct? -
Yes.
-
Many thanks!
-
@stephenw10 "1" should be disabled but i can't find the "dev.igb.X.eee_control" setting documented anywhere.
Freebsd lists it as "hw.em.eee_setting" with default as 1 for disabled
-
If you run
sysctl -d dev.igb.0.eee_controlyou should get a decription of the value. I don't have access to anything to test it on right now. -

I don't have access to anything to test it on right now.yes: "dev.igb.0.eee_control: Disable Energy Efficient Ethernet" - but doesn't tell you if a 1 or a 0. I suppose common sense says true to "disable" but i am only curious why it is not consistent with the freebsd for 14 which has eee_setting
p.s. I understand that I should have TSO and LRO disabled, but what about checksum offloading? I have 8x I211 in a headless qotom. Is it safe to hw checksum offload?
-
One is em and the other is igb.
-
@stephenw10 is it ok to enable hw checksum offloading, while leaving tso and lro disabled?
-
Yes, any of the hardware off-loading options can be enabled individually. They are usually not of much benefit when forwarding packets though.

Hi, I’m noticing link state changes with my Intel 211 card. Any advice on troubleshooting or workarounds? Thanks.

Could be explained by a power dip that didn't really reach your pfSense, but did had an effect on the device attached to igb0 and igb3.
-
@Gertjan Thanks for the reply, How can I verify if a power dip is the cause? It seems that igb1 and igb2 have far fewer link state DOWN logs.

Your pfSense usies an operating system (FreeBSD) with an (over) complex filesystem.
Like your PC (any OS) or MAC. removing the power (cable) can create major issues in the file system.
That's why 'mission' critical devices like your coffee machine an Internet access device are always fed by an UPS that filters out all power issues.
I said all this so you now also have a way to see if there were any power issues : the UPS will signal this.
And saving your devices while doing so.The connected devices to the pfSense on all your NICs are generally always switches (nad not end user devices), so hook these up to the UPS also and you'll never see any LINK UP/DOWN again.
You still see them ? Then, for every interface, on each side of the wire, change the NIC.
Or, it can happen : change the network cable.
Or tell the kids to stop pulling cables.It can happen, NICs (cables) can go bad, but the chance you see two of them failing at the same moment ? No way.
-
@Gertjan Thank you for pointing that out. I didn't even consider a power issue as a possible cause for the problem. Given that both NICs are experiencing the same issue, the possibility of a power issue seems more likely. Let me give it a try.
-
What are those NICs connected to? Are those devices also showing the link go down? Are they rebooting?
The time between those link change logs doesn't really look like flapping.
-
@stephenw10 Hi, here are the connections for each NIC, I’ve also tried changing the cable on igb0, but the issue persists.
igb0: Connected to the ONU (PR-600MI)
igb1: Connected to a WiFI Router
igb2: Connected to NAS (can be woken up via magic packet and goes to sleep when inactive)
igb3: Connected to Mac Studio (wakes up from sleep when needed)More Logs,

Unfortunately, my pfsense router won’t power on. I need to buy a new one. Can you recommend a stable brand that won’t break the bank? Thanks.
