Re: How to correctly create multiple bonding interfaces in kernel 188.8.131.52

Dan, Unfortunately, Debian based methods would not do much for me. I can try to experiment with lacp_rate .So the way I got it working in kernel 2.6.26 was actually this, in /etc/modprobe.conf:
install bond0 /sbin/modprobe --ignore-install bonding -o bond0 mode=balance-alb miimon=100 updelay=0 downdelay=0 install bond1 /sbin/modprobe --ignore-install bonding -o bond1 mode=802.3ad miimon=100 updelay=0 downdelay=0
Doing the same in 2.6.29, for bond1 (cross over between the 2 servers) a single ping would cause kernel panic.
Pings in bond0 (switch) would go on and off every 10 seconds or so... So...I will be trying to use similar options to these now in 2.6.29, maybe using sysfs ( /sys ) or... maybe rolling back to 2.6.26 and deal with other issues that I had with filesystems...
What else? Thanks, -----Original Message----- From: Dan White Cc: linux-net@xxxxxxxxxxxxxxx Sent: Tue, Feb 2, 2010 6:25 pmSubject: Re: How to correctly create multiple bonding interfaces in kernel 184.108.40.206

Folks, I am currently working with kernel 220.127.116.11-0.16.smp.gcc3.4.x86_64 .

Can anybody help me with that?I recently upgraded from kernel 2.6.26 which was working fine using something like in modprobe.conf:install bond0 /sbin/modprobe --ignore-install bonding -o bond0 >

, unfortunately kernel 2.6.29 does not seem to like these and when I test the bonding interfaces using just a ping, I got a kernel panic.Also, I have trying several different ways to configure the bonding interface, but it is never stable. Ping will work for 10 seconds, time out for another 0 or so and back
and > forth.Here are the bonding options I use (specified in /etc/modules on Debian):
bonding miimon=100 mode=4 lacp_rate=1 This has worked for me on the following kernels: 2.6.18-6-686 2.6.26-2-amd64 I have not tried newer kernels. You can obtain a list of options for bonding for your newer kernel with 'modinfo bonding'.Those options work well with my Cisco 3750 switch. Without these options set, I would only link up at 100meg (on gig interfaces) and/or I would drop
every other packet. Hope that helps. An FYI for other Debian users, you can bond like this in /etc/network/interfaces: auto bond0 iface bond0 inet static address 192.168.1.2 netmask 255.255.255.0 gateway 192.168.1.1 slaves eth0 eth1 (I have no eth0 or eth1 entries interfaces) -- Dan White--
