   Posted by: admin    in Linúc ếch bợt

Testing :

modprobe bonding  mode=4 miion=100 xmit_hash_policy=1

ifconfig bond0 192.168.253.101/24 up

ifconfig eth0 down

ifenslave bond0 eth0

ifenslave bond0 eth1

——— sh run ——-

!

interface Port-channel1

description Port channel for RHEL5-Server

switchport access vlan 105

switchport mode access

!

!

interface GigabitEthernet1/0/15

description This port is reversed for RHEL5-Server

switchport access vlan 105

switchport mode access

channel-protocol lacp

channel-group 1 mode active

!

interface GigabitEthernet1/0/16

description This port is reversed for RHEL5-Server

switchport access vlan 105

switchport mode access

channel-protocol lacp

channel-group 1 mode active

!

Finalizing :

put in your /etc/modules.conf :

alias bond0 bonding options bond0 mode=4 miimon=100 xmit_hash_policy=1

create ifcfg-bond0 file in /etc/sysconfig/network-scripts directory that looks like this:
DEVICE=bond0
IPADDR=192.168.1.1
NETMASK=255.255.255.0
NETWORK=192.168.1.0
BROADCAST=192.168.1.255
ONBOOT=yes
BOOTPROTO=none
USERCTL=no
All interfaces that are part of the trunk, should have SLAVE and MASTER definitions. For example, in the case of RedHat, if you wish to make eth0 and eth1 (or other interfaces) a part of the bonding interface bond0, their config files (ifcfg-eth0, ifcfg-eth1, etc.) should look like this:
DEVICE=eth0
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none
