Hi ,
I am trying to configure bond/trunk on RHEL 5.4 86_64 OS.
The bond/trunk works when I am using mode=1, ie
fault-tolerance (active-backup)
But when I am trying to configure with mode=4, ie 802.3ad
Dynamic link aggregation,
it is not working.
Here is the configuration I did:
- Considering one port for bonding , now only eth1 as it is a
test server has only one port
- the 3 subnets are being considered 12- 14
- Included bonding drivers. and the /etc/modprobe.conf
mentioned the parameters as
alias bond0 bonding
options bond0 mode=4 miimon=100 lacp_rate=1
- In /etc/sysconfig/network-scripts area created few config
files as follows;
ifcfg-bond0 : DEVICE=bond0
BOOTPROTO=none
>
Type=Ethernet
ifcfg-eth1 : DEVICE=eth1
USERCTL=no
>
MASTER=bond0
BOOTPROTO=none
HWADDR=xx:xx:xx:xx:xx:xx
SLAVE=yes
ifcfg-bond0.12 : DEVICE=bond0.12
>
TYPE=Ethernet
BOOTPROTO=static
IPADDR=xxx.xx.xx.xx
NETMASK=255.255.255.0
VLAN=yes
Similarly created ifcfg-bond0.13 and ifcfg-bond.14 like
ifcfg-bond0.12
- Here is the switch side configuration:
interface Port-channel60
description <server> trunk/channel
switchport trunk allowed vlan 1,12-14,460
switchport mode trunk
spanning-tree portfast trunk
end
xxx-es-bcs1#sh run int g1/0/4
Building configuration...
Current configuration : 192 bytes
!
interface GigabitEthernet1/0/4
description <server> trunk
switchport trunk allowed vlan 1,12-14,460
switchport mode trunk
channel-group 60 mode active
spanning-tree portfast trunk
end
- Kept tag 460 for future use ..
- I am getting the file in /proc/net/bonding/pbond0 not
bond0, here is the display
Ethernet Channel Bonding Driver: v3.4.0 (October 7, 2008)

Similary the other two subnets also.....
Really appreceated if anybody helps me out.
Thanks in advance

What type of switch do you have? Is it cisco or other? I have 802.3ad
working flawlessly on my setup which is similar to yours.
