Speed Interface error in QinQ interface

prx

Hi,

I have 2 Chelsio 4x10Gb SFP+ (T540-LP-CR) and I configured 3 laggs (failover). Then I configured vlan 100 on lagg2 and then I configured several QinQ interface on top vlan 100. Now everything works, but in the dashboard the speed of the QinQ interface is:

1000baseT <full-duplex>

instead of

10Gbase-LR <full-duplex>

The clx interfaces of the lagg2 (cxl2,cxl6 ) have the correct media:

10Gbase-LR <full-duplex>

this is my ifconfig output:

the questions are:

Why the QinQ interfaces media is 1000BaseT instead 10000Base-SR?
Is it correct that lagg0 (WAN) lagg1 (other net) media is "autoselect" and not 10000Base-SR?

Thank you

Hi,

Don't you usually disable LRO, TSO stuff?
These are not good if you are a router or only, if you are an endpoint...
https://calomel.org/freebsd_network_tuning.html

although even automatic speed negotion should work, if the setting on the other side is "auto"

+++edit:

also important:

Flow Control (FC) 0=Disabled 1=Rx Pause 2=Tx Pause 3=Full FC

This tunable must be set according to your configuration. VERY IMPORTANT!

Set FC to 0 (<x>) on all interfaces

hw.igb.<x>.fc=0 #Also put this in System Tunables hw.igb.<x>.fc: value=0

and / or

Disable Energy Efficiency - set for each igb port in your system
This setting can cause Link flap errors if not disabled
Set for every igb interface in the system as per these examples
dev.igb.0.eee_disabled: value=1
dev.igb.1.eee_disabled: value=1
dev.igb.2.eee_disabled: value=1
dev.igb.3.eee_disabled: value=1

Hi,

as you can see from the attachment, I disabled:

Hardware Checksum Offloading
Hardware TCP Segmentation Offloading
Hardware Large Receive Offloading

@DaddyGo
My NICs are 2 Chelsio T540-LP-CR (every nic has 4x10Gb SFP+ ports), so if I understood well, I have to add the following "lines" in Advanced->System Tunables:

hw.cxl0.fc value 0
hw.cxl1.fc value 0
hw.cxl2.fc value 0
hw.cxl3.fc value 0
hw.cxl4.fc value 0
hw.cxl5.fc value 0
hw.cxl6.fc value 0
hw.cxl7.fc value 0

and

dev.cxl.0.eee_disabled value 1
dev.cxl.1.eee_disabled value 1
dev.cxl.2.eee_disabled value 1
dev.cxl.3.eee_disabled value 1
dev.cxl.4.eee_disabled value 1
dev.cxl.5.eee_disabled value 1
dev.cxl.6.eee_disabled value 1
dev.cxl.7.eee_disabled value 1

is it right?

The speed negotiation is set on "auto" on the switches (Cisco nexus 3064-X). This is the running conf of the interface:

as you can see from the attachment, I disabled:

For some reason, this often doesn’t work the way we would expect
therefore, I would not rely on chance and use loader.conf.local
(you can also see that the box is checked and the feature is still active)

like... (loader.conf.local also protects against OP system (FW) changes!):

about the 10 Gig:
Perform a test related to speed and set the switch to fixed speed negotion...
let's see what happens

btw:

with a completely similar problem and we've been talking about this in the forum here for about 6 months now with a college student from the US
I can't find the posts, plus there was a positive result, so it would be worth looking for....

One more thing, what CPU you use and what MSI-X
what does this show:

dmesg | grep -i msi

prx

@DaddyGo said in Speed Interface error in QinQ interface:

dmesg | grep -i msi

Hi,

tomorrow I will modify loader.conf.local and I will configure PfSense and switch ports with fixed speed negotion.

My CPU is AMD EPYC 7272 12-Core and the output of dmesg | grep -i msi is:

xhci0: Unable to map MSI-X table 
xhci1: Unable to map MSI-X table

Thank you very much

AMD EPYC 7272

power machine...

@prx "tomorrow I will modify"
okay let's see what happens

btw:
I'm running on Epyc 3151 (Supermicro) with I350-T4 and I350-F4 (8 interfaces) it takes a long time for a well-tuned NIC setup

AMD is currently a good choice for a firewall...

a little plus for loader.conf.local...

Allows NIC to process packets as fast as they are received
hw.igb.enable_msix=1
hw.pci.enable_msix=1

(of course don't put it on "igb")

Then I have set manually, in the GUI, the speed interface on my QinQ interface to 10GBase-T <full-duplex>. The only thing I couldn't do was set up the the speed of my lagg (0,1,2) interfaces to 10G full-duplex. In the GUI under Assignments -> Interfaces I can only select "autoselect" and this is what I see in the dashboard. For example this is the output of ifconfig of the lagg2 (only media information...)

cxl2:
	media: Ethernet 10Gbase-LR <full-duplex,rxpause,txpause>
cxl6:
        media: Ethernet 10Gbase-LR <full-duplex,rxpause,txpause>

lagg2:
	media: Ethernet autoselect

lagg2.100:
        media: Ethernet autoselect

lagg2.100.20:
        media: Ethernet 10Gbase-T <full-duplex>

I was able only to force media on the lagg2.100.20 interface but not to its parents interfaces...

Thank you

@prx said in Speed Interface error in QinQ interface:

In the GUI under Assignments -> Interfaces I can only select "autoselect"

Due to the nature of "LAG", both sides require the same - next:

-Be of the same speed
-Have the same Duplex settings

When negotiating the LAG speed (merged), only "auto" can be considered, because of the above.

Just think along, two parent interface, which is 1Gig
in LAG (with LACP) 2 Gig

if one of the parent interfaces becomes detached, the combined speed will again be only 1 Gig, so the speed of the LAG interface cannot be predefined, but depends on the group members (from their number / speed)
