IP Networking

Hi Peasant,

Yes i have ran modprobe bonding. But the issue i am facing that it works fine when system boots up but ASA i restart the network service the whole thing stops, the bond0 interface never comes up.

Are you sure this is correct in your setup

/etc/sysconfig/network-scripts-ifcfg-bond0

Should be (atleast on my RHEL 6.2 Santiago)

/etc/sysconfig/network-scripts/ifcfg-bond0

Yes, this was just a type that i made while posting it here.

Hi Guys,

Finally i was able to resolve the issues i was facing in setting up Channel Bonding. It is working now but i am not very much sure about the results if they are correct.

I used two cars eth7 and eth8 to make a bond0 interface. The IP of the bond0 interface is 192.168.30.1. Now i try to ping this machine from my second test machine which has IP of 192.168.30.3 and it works fine. Now i try bringing the interface eth8 down using "ifdown eth8" and then ping again from test machine and it is successful, and then brought the interface eth8 again up using ifup eth8.

Now if i repeat the same for eth7 the ping stops working i.e. bringing eth7 down and keeping eth8 up and then ping from test machine i do not get ping responses even when one of the two bonded interfaces is up i.e. interface eth8 is up.

The Bonded interface bond0 is setup in round-robin mode(mode=0). I tried using the mode=1 also but got same results.

So can somebody please tell if it is working as it should work or there is some discrepancy in results.

Here are the config files

Network Interfaces config files

Code:

[root@prod ~]# cat /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE="bond0"
ONBOOT="yes"
BOOTPROTO="none"
IPADDR="192.168.30.1"
USERCTL="no"
BONDING_OPTS="mode=1 miimon=100"

[root@prod ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth7
DEVICE="eth7"
ONBOOT="yes"
BOOTPROTO="none"
MASTER="bond0"
SLAVE="yes"

[root@prod ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth8
DEVICE="eth8"

Thanks

Hi Guys,

Can anyone help me out on the queries made above.

Hi Rohit,

Were you able to resolve this? I have the same issue as yours.

Can you provide the output from the following:

Code:

cat /proc/net/bonding/bond0
