Bonding is the technology of aggregating several parallel channels in Ethernet network. The feature helps to balance server loading and increase fault tolerance.

We set up channel aggregation using the standard LACP protocol. It is paid feature, take a look at prices at the LACP tab.

To get bonding order the service Port Channel from the Control Panel, prepare your server and then contact us via ticket to set it up.

​
Server setup

​
Setup example for Ubuntu 14.04

Install ifenslave package before contacting us :

apt-get install ifenslave​

Add “bonding” to /etc/modules file.

Run modprobe load bonding immediately:

modprobe bonding

Make sure it’s loaded, you should see something like “bonding 147456 0”:

# lsmod | grep bonding 

bonding 147456 0

​
Configure LACP on the server

After LACP is ready from our side you need to configure it on the server.

Stop network services:

stop networking

Edit network interfaces settings:

vim /etc/network/interfaces

using the following example (replace em1 and em2 to your network interface names):

auto em1 

iface em1 inet manual 

bond-master bond0 

bond-primary em1 

 

auto em2 

iface em2 inet manual 

bond-master bond0 

 

auto bond0 

iface bond0 inet static 

 address 92.223.103.25 

 gateway 92.223.103.1 

 netmask 255.255.255.0 

 

bond-mode 4 

bond-miimon 100 

bond-lacp-rate 1 

bond-slaves em1 em2

Changes will apply after you do the following:

start networking

If there is no network connection in the bonding, reboot your server.

You can check the bond0 status:

cat /proc/net/bonding/bond0
