How to configure the virtual Interface in R900

[christian.peper at kpn.com]

Nitin,

It really isn't too hard. It's been asked here before on the list, so
search the archive as well for hints and tips. :) BTW, I'm using OEL
4u5, almost identical to RHEL4u5 on a Dell PE2950 (the old one).

I've collected some references here:

Feel free to check them. The fail-over mode used below is explained in
one of the blogs.

Basically, you setup 3 ifcfg files, one for the logical bond and 2 (or
more) for the underlying pyshical NICs. 
Here is what I use:
/etc/sysconfig/netword-scripts/ifcfg-bond0
DEVICE=bond0
USERCTL=no
ONBOOT=yes
BROADCAST=10.x.y.255
NETWORK=10.x.y.0
NETMASK=255.255.255.0
GATEWAY=10.x.y.1
IPADDR=10.x.y.65

/etc/sysconfig/netword-scripts/ifcfg-eth0
DEVICE=eth0
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none

/etc/sysconfig/netword-scripts/ifcfg-eth4
DEVICE=eth4
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none

/etc/modprobe.conf
# bond0 devices eth0 and eth4
# mode=0 loadbalance and failover
# mode=1 failover
alias bond0 bonding
options bonding miimon=100 mode=1
# end bond0
alias eth0 bnx2
alias eth1 bnx2
alias eth2 e1000
alias eth3 e1000
alias eth4 e1000
alias eth5 e1000
