[Cialug] NIC Teaming/Bonding and Vlans

[Matt Patterson]

Oh, I know it works. I have several boxes already setup with bonding + 
vlan.  Most are SuSE boxes.  But I have gotten it working on debian and 
redhat before.  But for some reason, I've run into this issue and can't 
figure out how to get around it.  The modules are all loaded.  The bond 
can be setup.  The only thing that I am thinking of is that there is a bug 
in 2.6.16 with vlans and bonding.

# modprobe --list | grep -i bonding
/lib/modules/2.6.16-qla2300-custom/kernel/drivers/net/bonding/bonding.ko

# modprobe --list | grep -i mii
/lib/modules/2.6.16-qla2300-custom/kernel/drivers/net/mii.ko

# modprobe --list | grep -i 8021q
/lib/modules/2.6.16-qla2300-custom/kernel/net/8021q/8021q.ko


For those running debian and looking for a good tutorial on how to setup 
vlans, I suggest this site:
