Fedora 17 and NIC bonding

[Bonus]

Hi,

I'm trying to bond 4 gig nics (Intel I350 quad network card) in fedora 17, but I can't get it to work. I want to use LACP (mode=4), but as soon as I restart network services my switch goes bananas and the network goes down.

Anyone who have any idea whats wrong here ? I'll be greatful for help that solve my problem...

My switch is a Netgear GS724T and I've configured LAGS and LACP as described in the manual.

Heres what I've done:
1. Stopped and disabled NetworkManager
2. Started and enabled network service

Physical nics in host:
1. em1 (this is my management nic and not a member in any bonding, mb onboard nic)
2. p1p1
3. p1p2
4. p1p3
5. p1p4

Heres my config on my linux host:
ifcfg-bond0
DEVICE=bond0
NM_CONTROLLED="no"
IPADDR=192.168.20.20
NETMASK=255.255.255.0
#GATEWAY=192.168.20.1
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none
USERCTL=no

ifcfg-p1p1
#UUID="dea0d5f3-0e06-4573-98e7-25ac50256bbb"
NM_CONTROLLED="no"
#HWADDR="A0:36:9F:03:10:10"
BOOTPROTO=none

#HWADDR="A0:36:9F:03:10:11"

BOOTPROTO=none
DEVICE="p1p3"
ONBOOT="yes"
MASTER=bond0

ifcfg-p1p4
#UUID="9441b346-60bc-4afe-a0d4-220f21d56104"
NM_CONTROLLED="no"
#HWADDR="A0:36:9F:03:10:13"
BOOTPROTO=none
DEVICE="p1p4"
ONBOOT="yes"
MASTER=bond0
SLAVE=yes

/etc/modprobe.d/bonding.conf
alias bond0 bonding
options bond0 miimon=100 mode=4


Thanx!

Hi again,

I've just got the server and the switch to like each other. The switch doesn't reboot when the bond interface get active. The issue about that was related to a bug in the Netgear switch firmware.

Now - the bond interface comes up and seems to work internally, but I can't communicate with other servers via this interface.

I noticed that when I ping the servers bond interface from another server, I get "Destination Host Unreachable". BUT - when I restart the network service on my Fedora server I get one or two replies from the bonded NIC! What could cause this ?

Thanks...

A little late here but anyway - it would appear that you've commented out the gateway line in the bond0 config so the host doesn't know where to forward non-local packets to.
