in/out packets in Interfaces status page mismatch netstat,systat,tcpdump

DomiX

Hi,

I'm using a Dell R710 with 3 interfaces QLogic NetXtreme II BCM5709 (bce0:LAN, bce1:SDSL, bce2:Fiber) on 2.4.4-p3.
Everything works as expected (OpenVPN server). Statistics for bce1 in interfaces status page is not accurate. 21,7GB transfered with a 2Mb/s something is wrong, this connecion is used for backup OpenVPN but it's the default route for pfsense. Most traffic is DNS, NTP...

netstat and systat for others interfaces shows correct transfer with in/out >4GB

With

tcpdump -i bce1 or 
tcpdump -i pflog0 -ettt on bce1

I do not see huge traffic.
I'm also monitoring this server with zabbix Agent and bce1 traffic is nearly 0

Why this difference with interfaces status page (from code pfctl -vvsI -i bce1) and others network tools for traffic usage ?

Thanks in advance for your help.

@DomiX said in in/out packets in Interfaces status page mismatch netstat,systat,tcpdump:

100baseTX <half-duplex>

Is it actually running at 100Mb-HD?

If not it seems like the NIC/driber is not reporting correctly.

You might check the mac stats in the sysctl output to see which it agrees with.

Hi,

I changed the ethernet cable with a 6a model and it's still 100TX half-duplex. I tried with Windows 10 and it's also half-duplex. It's connected to a Cisco C888EA (unfortunatly I do not have access, I opened a ticket to my provider for more information).

What do mean by checking mac stats in sysctl ?

@stephenw10 According to my provider, the port is configured in 100M full-duplex but negotiation disabled.
I forced full-duplex on pfsense and rebooted but traffic is still high in status interfaces pages but systat and netstat are low.

Hmm, the mac stats look very low. That looks to agree with ifstat then.

You're sure it's bce1 and not bce0? Do the stats for any bce NIC look correct?

@stephenw10
Yes, bce1 statistics are not correct with pfctl (interfaces status page). Others statistics for bce0 (LAN) or bce2 (WAN 200Mb/s) are correct.
