EX 4200 and Bonded interfaces in Centos 5.x

Hi All,

Just wanted to post some information about a configuration I had some trouble with, but managed to find a solution to. I was trying to setup an aggregated link on an EX 4200 switch to a bonded interface on a Centos 5.x server. The only way I could get it to work was using the following configuration:

 

On the EX 4200 switch I created an aggregated link (ae0) and assigned 2 ports to the link. I then set the link to use lacp in passive mode. I also added the switches to be a part of the management VLAN of which the switch is assigned ip address 192.168.1.254.

 

On the linux machine I setup 2 NICs to be bonded (BOND0) then in /etc/modprobe.conf I added the following:

 

alias bond0 bonding
options bond0 miimon=100 arp_ip_target=192.168.1.254 mode=4 lacp_rate=1

 

I loaded the bonding interface with modprobe bond.

 

Now it all works for me...

Thanks for the help, we def referenced this post when we were hooking up some of our servers to an 8208 via bond !
