Hi,
Following up on this, placing the script into /etc/rc.conf.lagg and
configuring/including it in rc.conf with:
lagg_dev="lagg0"
lagg_devs="igb0 igb1 igb2 igb3"
Solves the issue.
if [ -n "${lagg_dev}" ]; then
/sbin/ifconfig "${lagg_dev}" create > /dev/null 2>&1
if [ $? -eq 0 ]; then
/sbin/mount -t tmpfs tmpfs /tmp
/bin/cp /rescue/ifconfig /tmp
addr=`kenv boot.netif.ip`
netmask=`kenv boot.netif.netmask`
bootif=`kenv boot.netif.name`
if_lagg_devs=`echo ${lagg_devs} | sed "s/ / laggport /g"`
for dev in ${lagg_devs}
do
/tmp/ifconfig ${dev} up
done
ifconfig ${lagg_dev} up
ifconfig ${lagg_dev} ${addr} netmask ${netmask} laggproto \
lacp laggport ${if_lagg_devs} up
ifconfig ${bootif} -alias ${addr}
/sbin/umount /tmp

Hi,
I have several netbooted machines, which operate in this way:
- the machine boots up from one interface (PXE, DHCP), for example igb0
- during the boot, an rc script runs* which deletes the IP from igb0
and creates the lagg interface with igb0, igb1 etc and sets the
original IP on that interface (with a statically linked ifconfig)
- normal booting continues from the lagg interface
This has worked for years and broke somewhere in the lifecycle of
10-STABLE.
Now I can't remove the IP address from the interface, ifconfig igb0
delete gives:
interface igb0 cannot change link addresses!
Any ideas about how could I work around this?
Basically I would like to switch the IP from one interface to another
while running from an NFS root. (and this has worked before svn rev xxx)
Thanks,
