Hi,

I'm currently doing a RHEL5 cluster setup. My hardware is:

IBM HS21
2 Cisco switches in the blade chassis
2 Cisco 7600's doing hsrp as gateways for the VLAN the cluster nodes are sitting on.

The bonding part of my /etc/modprobe.conf is like:

alias bond0 bonding
options bond0 arp_interval=200 arp_ip_target=172.31.3.254 mode=1 primary=eth0

(172.31.3.254 is the gateway of the private network i am using).

My eth0/eth1/bond0 config files:
ifcfg-eth0:
# Broadcom Corporation NetXtreme II BCM5708S Gigabit Ethernet
DEVICE=eth0
USERCTL=no
ONBOOT=yes
BOOTPROTO=none
MASTER=bond0
SLAVE=yes

ifcfg-eth1:
# Broadcom Corporation NetXtreme II BCM5708S Gigabit Ethernet
DEVICE=eth1
USERCTL=no
ONBOOT=yes
BOOTPROTO=none
MASTER=bond0
SLAVE=yes

ifcfg-bond0:
DEVICE=bond0
ONBOOT=yes
BOOTPROTO=none
IPADDR=172.31.3.200
NETMASK=255.255.255.0
GATEWAY=172.31.3.254
USERCTL=no

Both network cards are on the correct VLAN. I've tried doing ip addresses on both of them and they are able to reach the gateway and get ARP from it.

Now when i bring up my bond0 interface and switch the active nic to another VLAN, the bonding driver does not disable that interface.

Has anyone seen this behavior? Has anyone gotten this to work?

Thanks,
Finnur
