Hi pfSense Team,

i have a problem with my NSA-1041 Hardware. Since 1.2.3 RC2 VLANs are not working. (Also the release version). Normal networking without VLANs works.
Releases before 1.2.3 RC2 are working fine.

Was there a driver change or sth. else?

My Southbridge is a VT8235M.

Can anyone give me a hint to get the 1.2.3 relase working?

[Perry]

Things you can try.
Upgrade firmware/bios
Post ifconfig and pciconf -lv of the nic here
Install a stock freebsd 7.2 to confirm problem

[wallabybob]

It might also help to elaborate on "VLANs are not working."

[mibo]

So here some informations


if you configure a VLAN it fells like no network connection. Interface (physical and vlan) is up, but no traffic.

i have seen that between RC1 and RC3 freebsd was updated to 7.2. and now i have more options in the interfaces than before. can a new default interface option cause this?

here my testing plan:

- booting from LiveCD. No harddisk. working with defaults.
- setup vlan0 on fxp1
- setup lan on fxp0. connected to my notebook
- setup wan on vlan0. connected to DHCP Server (company LAN)

now you can not reach any host behind WAN(vlan). it doesnt matter if i test on my notebook or in the ssh shell.

with freebsd 7.1 (1.2.3 RC1) it works.

[Perry]

Warning for those using Intel PRO/100 cards – there is a regression in the fxp driver in FreeBSD 7.2 that may require disabling hardware checksum offloading under System -> Advanced if you have connectivity problems.

[mibo]

i have tried disabling hardware checksum offloading but no luck...

on fxp0 the RXSUM and TXSUM option disappeared, but on vlan0 and fxp1 not.

[Perry]

You could try the manual way
ifconfig fxp0 -rxcsum -txcsum

[mibo]

sorry.. did not work. the option disappears but it still not work..

i had a look at a packet capture. At the DHCP discover on the WAN interface i can not see a VLAN tag.
other packet from my network come with a correct VLAN tag.


the vlan id is 10 and the following value appears in the ip packet:

Code:

Differentiated Services Field: 0x10 (DSCP 0x04: Unknown DSCP; ECN: 0x00)
0001 00.. = Differentiated Services Codepoint: Unknown (0x04)
.... ..0. = ECN-Capable Transport (ECT): 0
.... ...0 = ECN-CE: 0

i think the vlan tagging is not working correctly...

[jimp]

If it's not working properly, it must be something specific to your fxp chip revision.

I'm using VLANs heavily on fxp cards on 1.2.3-RELEASE and it works just fine for me, either with onboard NICs or add-in cards. It does look like yours have tso, you might try disabling that if it isn't already:

Code:

sysctl -w net.inet.tcp.tso=0

The output of these commands might also help:

[jimp]

Looks like yours has a later chip revision and claims to do VLANs in hardware. Mine doesn't claim such support, not sure any of them do.

Perhaps it's a problem along those lines, but unfortunately it's a bit beyond my level of expertise. It might be interesting to try a stock FreeBSD 7.2 install on there to see if you have similar problems, or it may be easier to try a pfSense 2.0 beta snapshot to see if the problem persists on FreeBSD 8.

[mibo]

So i have tested a pfSense 2.0 snapshot.
The same tests as before were made but the problem also exists in this version with the same behaviour.

Any idea how to proceed?


I have found the following lines in the FreeBSD Release Notes:

The fxp(4) driver has been improved. Changes include:
- Rx checksum offload support for 82559 or later controllers has been added
- VLAN hardware tag insertion/stripping support and Tx/Rx checksum offload for VLAN frames support have been added. Note that the VLAN hardware assistance is available only on 82550 or 82551-based controllers.

pfSense recognize my card as a "Intel 82559ER". Can the VLAN hardware support be the issue? Like using VLAN hardware tag but my card cannot do this?

[jimp]

Try this:

Code:

ifconfig fxp0 -vlanhwtag -vlanhwfilter

Not sure about the hwfilter but try it anyhow, if it doesn't work, try just -vlanhwtag

That should disable the hardware tagging. If that works, install the shellcmd package and add a command in there for that. Might help for now.

[mibo]

Solved!
at first sight.

only disabling hwtag.

Code:

ifconfig fxp0 -vlanhwtag

I will do some more tests on the system till it goes back as my carp slave (with many VLANs ;-)).


Thanks a lot for your help!
