Channel Bonding problem

[PIGNOL, Christian]

Hello everybody,

I'm trying to use without success the "channel bonding" with 3 ethernet
adatpters "Inter Ether Pro 10/100" ... on a Fedora Core 1.B with a
2.4.22-1.2179.xxx kernel (With Posix Acl patches).

The 3 network interfaces (eth0 eth1 & eth2) comes up at boot as I can see on
my switch console (at 10/Half  or at 100/Full) but my "bond0" don't respond
to any incoming or outcoming request ... 

Please find below my configuration :

/etc/modules.conf :
alias usb-controller usb-uhci
alias usb-controller1 ehci-hcd
alias sound-slot-0 i810_audio
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null
2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null
2>&1 || :
alias eth0 e100
alias eth1 e100
alias eth2 e100
alias bond0 bonding
options bond0 mode=6 miimon=100

/etc/sysconfig/network-scripts/ifcfg-bond0 :
# Please read /usr/share/doc/initscripts-*/sysconfig.txt
# for the documentation of these parameters.
DEVICE=bond0
BOOTPROTO=none
ONBOOT=yes
NETWORK=54.104.90.0
BROADCAST=54.104.90.255
NETMASK=255.255.255.0
IPADDR=54.104.90.224
USERCTL=no
PEERDNS=no
TYPE=Unknown
GATEWAY=54.104.90.254

/etc/sysconfig/network-scripts/ifcfg-eth0 :
# Please read /usr/share/doc/initscripts-*/sysconfig.txt
# for the documentation of these parameters.
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=YES
USERCTL=no

/etc/sysconfig/network-scripts/ifcfg-eth1 :
# Please read /usr/share/doc/initscripts-*/sysconfig.txt
# for the documentation of these parameters.
DEVICE=eth1
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=YES
USERCTL=no

/etc/sysconfig/network-scripts/ifcfg-eth2 :
# Please read /usr/share/doc/initscripts-*/sysconfig.txt
# for the documentation of these parameters.
DEVICE=eth2
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=YES
USERCTL=no

During boot the following sequence of messages appears in the
/var/log/messages ...
 ...
May  6 16:53:46 fruxts05 kernel: bonding.c:v2.4.1 (September 15, 2003)
May  6 16:53:46 fruxts05 kernel: In ALB mode you might experience client
disconnections upon reconnection of a link if the bonding module updelay
parameter (0 msec) is incompatible with the forwarding delay time of the
switch
May  6 16:53:46 fruxts05 kernel: bond0 registered with MII link monitoring
set to 100 ms, in adaptive load balancing mode.

...

At this point ... my "bond0" device don't work !

When the system is ready, if I try a "/etc/init.d/network restart" command I
obtain the followings messages ...

But ... It don't work anymore ... My system is out of the network !


Thanks a lot for those persons who try to help me.
