To set or change the mode, type:
0002:network$ ip link set bond0 mode <mode>
ip link set bond0 mode 0
To see what mode is currently in use type:
0002: network$ ip link show bond0
The output of this command displays the physical link settings on the system. You can use it to verify any
changes to the physical link settings:
Example:
Device State MTU Mediatype Speed
eth0 UP 1500 copper auto
eth1 UP 1500 copper auto
Device State MTU Mode
bond0 UP 1500 0
Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)
Bonding Mode: load balancing (round-robin)
MII Status: down
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0
SUCCESS: show ip link
6. To disable or break up a bonded NIC device, you can use either the delete or flush command. The delete
command will only delete a specific IP address (multiple can be assigned) and flush will clear all assigned IP
addresses.
0003:network$ ip address delete <ip_address>/<subnet_mask> dev bond0
or
0003:network$ ip address flush bond0
Routes that are associated with this bonded NIC device will also be deleted.
Bonding driver modes
The modes specify bonding policies. Some options for certain modes are configurable (the transmit hash policy for
bonding modes 2 and 4, and the updelay for bonding mode 6), while the others take the default values for those
modes, except for the miimon setting.
The transmit hash policy for bonding modes 2 and 4, is used for slave selection in these modes. To set the transmit
hash policy for mode 2 or 4, use the ip link set command, for example;
0004:network$ ip link set bond0 mode 2 xmithashpolicy layer2+3
To view the changes, use the ip link show command;
Device State MTU Mediatype Speed
eth0 UP 1500 copper auto
eth1 UP 1500 copper auto
Device State MTU Mode
bond0 UP 1500 2
Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)
Bonding Mode: load balancing (xor)
