Yes, this has to do with changes to the driver to fix bugs in its VLAN
hardware filter.  If you grab the latest 8-stable it should be back to
working fine by default.  If you enable 'vlanhwfilter' via ifconfig you will
loose link when adding or removing vlan's again.

e1000 + vlan = connection lost after ifconfig + vlanid + vlandev

2010-11-22 Thread Rudolph Sand
Hi, I noticed that *something has changed* regarding vlan creation since 
8.0-rel and 7.1-rel, compared to 8.1-rel / 7-stable

When creating a vlan under 8.1-rel (csup'ed the sources yesterday), the box 
looses all connectivity

I'm using the following cards:
e...@pci0:1:0:0:class=0x02 card=0x10d315d9 chip=0x10d38086 rev=0x00 
hdr=0x00
vendor = 'Intel Corporation'
device = 'Intel 82574L Gigabit Ethernet Controller (82574L)'

I was used to create my vlan with the following (works on 8.0 and 7.1):
ifconfig vlan0 create
ifconfig vlan0 10.0.0.1 netmask 255.0.0.0 vlan 1234 vlandev em0


Now I don't have the proper knowledge to say *what* changed and *why*, but I 
did manage to find a possible fix (with a little inspiration, thanks Darius)

At some point, I realized the kernel wasn't panic'ing, since my 'sleep 200 && 
reboot &' command, issued before the ifconfig, was executed, and the box was 
indeed rebooting after 200 secs

... Bottom line, is we realized a simple "ifconfig em0 down" than "ifconfig em0 
up" would fix the issue !

So i made a simple script for /usr/local/etc/rc.d/000.vlan.sh enclosed below

I'm still wondering if there isn't a cleaner way to do this via rc.conf ...

But at least, it's a working fix-of-the-poor

Home this can still help someone

Ps: sorry if this is the wrong place to post this info, that's my very first 
humble contribution

Rud.



000.vlan.sh :
-
#!/bin/sh

ip=10.0.0.1
mask=255.0.0.0
vlanid=1234
vlandev=vlan0
cloneddevice=em0

case $1 in
   start)
   log=/var/log/vlan.log
   touch $log
   ifconfig $vlandev create >> $log
   ifconfig $vlandev $ip netmask $mask vlan $vlanid vlandev 
$cloneddevice >> $log
   ifconfig $cloneddevice down >> $log  
  
   ifconfig $cloneddevice up >> $log
  
# for debug ...
# mv /usr/local/etc/rc.d/000.vlan.sh /root/000.vlan.sh && sleep 800 && reboot & 
   
   ;;   
   stop)
   ;;   
esac
