8.11. Controlling teamd with teamdctl
In order to query a running instance of
teamd for statistics or configuration information, or to make changes, the control tool teamdctl is used.
To view the current team state of a team team0, enter the following command as
root:
~]# teamdctl team0 state view
For a more verbose output:
~]# teamdctl team0 state view -v
For a complete state dump in JSON format (useful for machine processing) of team0, use the following command:
~]# teamdctl team0 state dump
For a configuration dump in JSON format of team0, use the following command:
~]# teamdctl team0 config dump
To view the configuration of a port em1, that is part of a team team0, enter the following command:
~]# teamdctl team0 port config dump em1
8.11.1. Add a Port to a Network Team
To add a port em1 to a network team team0, issue the following command as
root:
~]# teamdctl team0 port add em1
Important
If using
teamdctl directly to add a port, the port must be set to down. Otherwise the teamdctl team0 port add em1 command will fail.
8.11.2. Remove a Port From a Network Team
To remove an interface em1 from a network team team0, issue the following command as
root:
~]# teamdctl team0 port remove em1
8.11.3. Applying a Sticky Setting to a Port in a Network Team
You can use the
teamdctl command to apply a sticky setting to ensure that a specific port is used as an active link when it is available.
Prerequisites
- You already created a team of network interfaces. As a result, you have a port (em1) that you want to update the configuration of.
Procedure
To apply a JSON format configuration to a port em1 in a network team team0, run the following commands:
- Update the configuration of the sticky setting for em1:
~]#
teamdctl team0 port config update em1 '{ "prio": 100, "sticky": true }' - Remove em1:
~]#
teamdctl team0 port remove em1 - Add em1 again so that the sticky setting takes effect:
~]#
teamdctl team0 port add em1Note that the old configuration will be overwritten and that any options omitted will be reset to the default values. See theteamdctl(8)man page for more team daemon control tool command examples.
8.11.4. View the Configuration of a Port in a Network Team
To copy the configuration of a port em1 in a network team team0, issue the following command as
root:
~]# teamdctl team0 port config dump em1
This will dump the JSON format configuration of the port to standard output.
