Red Hat 5 Bonding Nics

Darren Etheridge_2 — Sun, 25 Apr 2010 17:24:41 GMT

I have 2 Nics I have bonded on my RedHat server. The teaming(bonding) works great but I don't have a trunk(LACP) setup in the Procurve 5408xl switch. When I try to setup a trunk, the link of the RedHat bonds fail. Am I missing something? Don't I need to Trunk the ports the NICS are on in the switch for this to work correctly?

Any input would be greatly appreciated!@

There are 6 modes to the config. the default is not a trunk / aggregate...

I believe mode 6 is the one you are looking for, double check the doc though....

LACP protocol should match at server and switch side.

Shalom,

Please post /etc/modprobe.conf

You may need to choose a different bonding mode to get around this issue.

I used Mode 4, 802.3ad and it seems that the switch auto set the Dyn Trunk automatically. I am looking for more bandwidth and redundancy. Would this mode be ok to use?

ifcfg-bond0:

NETWORK=192.168.1.0
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
USERCTL=no
BOOTPROTO=none
ONBOOT=yes
IPV6INT=no

ifcfg-eth0:

MASTER=bond0
SLAVE=yes
BOOTPROTO=none

ifcfg-eth1:
