RTM-ATCA-SXXX Overview

4.8.1Bonding, CLI command syntax

The Linux community has created an extensive man page for ifenslave. The subset of essential elements is summarized below.

Create new bond

Step1:		ifconfig eth0 down; ifconfig eth1 down
		Deactivate the Ethernet “slave” ports that will become bond members
Step2:		modprobe bonding mode=0 miimon=100
		This loads the bonding module, sets the usage policy mode and sets polling
		frequency to 100mS. Several mode exist, but these are the most common
		Valid mode=[ ] options:.
		mode=0 - Round robin packet, or balanced transmit policy. This mode will
		only work with switches that support trunking.
		mode=1- Active-backup; one slave port is active, the other is passive. This
		mode should work with any Layer-II switch.
Step3:		ifconfig bond0 <ip-address> up
		Define a new bond0, and assign a dotted decimal <ip-address >. Note: the
		MAC address of the bond0 device will be taken from the first slave device.
Step4:		ifenslave bond0 eth0; ifenslave bond0 eth1
		Assign the slave ports that will comprise the new bond.
Preserve new		/etc/rc.d/init.d/userstart
bond attributes
		This file contains a template for adding commands that will be executed on
		boot (or shutdown) as required by the user. This file is stored in system flash
		memory and preserved over reboots. Edit this file and add the entire
		sequence of bond commands.
		Example:
		ifconfig eth0 down; ifconfig eth1 down
		modprobe bonding mode=0 miimon=100
		ifconfig bond0 <ip-address> up
		ifenslave bond0 eth0; ifenslave bond0 eth1 eth1
Remove bond
Step1:		ifenslave -d bond0 eth0; ifenslave -d bond0 eth1
		Remove all Ethernet “slave” ports that are bond members
Step2:	ifconfig eth0 down; ifconfig eth1 down
		Set the former slave ports as down.
Step3:		/etc/rc.d/init.d/userstart
		Remove the relevant bond creation code, and reboot
