Configuring Link Aggregation in aLinux 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:

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:

3. Configure bond0 interface.

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

alias bond0 bonding

options bonding max_bonds=2 mode=4 miimon=1000

#modprobe bonding

#ip addr add 192.12.38.64/24 brd + dev bond0

#ip link set dev bond0 up

#ifenslave bond0 eth4 eth5
