Configuring Link Aggregation in a Linux Environment

This section explains how to configure link aggregation in a Linux environment.

▼To Configure Bonding for Multiple nxge Interfaces

1.Modify the /etc/modprobe.conf file for 2.6 kernels file by adding these lines:

alias bond0 bonding

options bonding max_bonds=2 mode=4 miimon=1000

where:

■bond0 is the bonding device.

■max_bonds is the number of bond interfaces to be created.

■mode specifies the bonding policies.

■miimon is the frequency in milliseconds that MII link monitoring will occur. Refer to Linux documentation for more information.

2.Load the bonding driver:

#modprobe bonding

3.Configure bond0 interface.

In this example, bond0 is the master of the two interfaces eth4 and eth5.

#ip addr add 192.12.38.64/24 brd + dev bond0

#ip link set dev bond0 up

#ifenslave bond0 eth4 eth5
