I followed process for bonding which is given on this site: https://help.ubuntu.com/community/UbuntuBonding

but output is

$ cat /proc/net/bonding/bond0 
Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)
Bonding Mode: load balancing (round-robin)
MII Status: down
MII Polling Interval (ms): 0
Up Delay (ms): 0
Down Delay (ms): 0

and

$ ifconfig
bond0     Link encap:Ethernet  HWaddr 86:df:fa:d9:19:30  
          inet addr:172.16.71.11  Bcast:172.16.71.255  Mask:255.255.255.0
          UP BROADCAST MASTER MULTICAST  MTU:9000  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:1314 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1314 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:89822 (89.8 KB)  TX bytes:89822 (89.8 KB)

And the status of other two device eth0 and eth1 shows that 'device not managed', So what should I do?

Before applying bonding, need to close network. In my case, following command is used:

sudo stop network-manager

Instead of:

sudo stop networking

After editing in sudo vi /etc/network/interfaces file, need to restart network using:

sudo start network-manager

Or reboot Ubuntu.

Its works fine, but still I don't know why it show:

device not managed
  • Device not managed means that the Ubuntu Network Manager is not managing the device, occurs when you configure interfaces via /etc/network/interfaces... – MDilmore Jun 5 '17 at 11:50
