8.6. Converting a Bond to a Team
It is possible to convert existing bonding configuration files to team configuration files using the bond2team tool. It can convert bond configuration files in
ifcfg format to team configuration files in either ifcfg or JSON format. Note that firewall rules, alias interfaces, and anything that might be tied to the original interface name can break after the renaming because the tool will only change the ifcfg file, nothing else.
To see some examples of the command format, issue the following command:
Copy to Clipboard
Copied!
Toggle word wrap
Toggle overflow
New files will be created in a directory whose name starts with
bond2team --examples
~]$ bond2team --examples
/tmp/bond2team.XXXXXX/, where XXXXXX is a random string. After creating the new configuration files, move the old bonding files to a backup folder and then move the new files to the /etc/sysconfig/network-scripts/ directory.

add the
bond0 configuration to team ifcfg, issue a command as root:
/usr/bin/bond2team --master bond0
~]# /usr/bin/bond2team --master bond0
bond0. To use a new name to save the configuration, use the --rename as follows:
/usr/bin/bond2team --master bond0 --rename team0
~]# /usr/bin/bond2team --master bond0 --rename team0
--json option to output JSON format files instead of ifcfg files. See the teamd.conf(5) man page for examples of JSON format.
Example 8.2. Convert a Bond to a Team and Specify the File Path
To convert a current
Copy to Clipboard
Copied!
Toggle word wrap
Toggle overflow
add the
bond0 configuration to team ifcfg, and to manually specify the path to the ifcfg file, issue a command as root:
/usr/bin/bond2team --master bond0 --configdir /path/to/ifcfg-file
~]# /usr/bin/bond2team --master bond0 --configdir /path/to/ifcfg-file
--json option to output JSON format files instead of ifcfg files.
Example 8.3. Create a Team Configuration Using Bond2team
It is also possible to create a team configuration by supplying the bond2team tool with a list of bonding parameters. For example:
Copy to Clipboard
Copied!
Toggle word wrap
Toggle overflow
Ports can also be supplied on the command line as follows:
Copy to Clipboard
Copied!
Toggle word wrap
Toggle overflow
/usr/bin/bond2team --bonding_opts "mode=1 miimon=500"
~]# /usr/bin/bond2team --bonding_opts "mode=1 miimon=500"
/usr/bin/bond2team --bonding_opts "mode=1 miimon=500 primary=enp1s0 \ primary_reselect-0" --port enp1s0 --port enp2s0 --port enp3s0 --port enp4s0
~]# /usr/bin/bond2team --bonding_opts "mode=1 miimon=500 primary=enp1s0 \
primary_reselect-0" --port enp1s0 --port enp2s0 --port enp3s0 --port enp4s0
