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:
em0@pci0:1:0:0: class=3D0x020000 card=3D0x10d315d9 chip=3D0x10d38086 =
rev=3D0x00 hdr=3D0x00
vendor =3D 'Intel Corporation'
device =3D '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
<connectivity lost>
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.
