On Debian first install the ifenslave package, necessary to enable bonding:
- Code: Select all
apt-get install ifenslave
Decide which bonding mode is desired for your needs. Full list can be find in original documentation.
Set kernel module options in /etc/modprobe.d/bonding.conf:
- Code: Select all
alias bond0 bonding
options bonding mode=4 miimon=100 lacp_rate=1 xmit_hash_policy=1
Example of link aggregation with Link Aggregation Control Protocol (LACP) bonding and transmit hash policy set to layer2+3 mode.
/etc/network/interfaces:
- Code: Select all
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet manual
bond-master bond0
auto eth1

Restart network interfces to apply changes:
- Code: Select all
/etc/init.d/networking restart
And check status of bond0 interface:
- Code: Select all
