The devices must be configured with the IPs of all three controllers in a team.
(optional) Enter inputs for other regions you want to define. You can specify
1, 2, or 3 regions in a team, or no regions. If you don’t want to define Region2
or Region3 then leave all items for that region blank.

Using a Python script from a controller to configure a team
You can configure teaming using a Python script (
conf_team.py
) and a configuration file on
any active controller you plan to include in the team. For details on the teaming requirements,
see
“High Availability best practices” (page 99)
From a controller, the script allows the following teaming configuration actions: create a team,
create regions within a team, add devices to a region, disband a team, delete regions within a
team, remove devices from a region.
To use the script you must
ssh
to one of the controllers you plan to include in the team. For
example,
(then enter the
ssh
password). You do not need to
ssh
to the
other two controllers in the team.
The Python script
conf_team.py
is run from the controller you
ssh
into. You edit a configuration
file on that same controller to define the inputs you want to use when running the script. The
default configuration file is
build_team.conf
. The file is on the controller system at
/opt/
sdn/scripts/teaming/build_team.conf
. (The
/opt/sdn
path may not be visible to the
ssh
user. The user must be part of the
sdn
group to see the directory structure). You can edit
this file or you can create a custom configuration file with a different name but the same format
and in the same directory.
For details on using the configuration file, see
“Defining inputs for teaming in a configuration file”
Once you have all the inputs you want to use for team configuration in the configuration file, you
run the script. By running the script,
/opt/sdn/scripts/teaming/conf_team.py
you can
access all the team configuration actions.
To run the script:
1.
The command to run the script is:
python conf_team.py
[config file name]
[-v]
[config file name]
. Default is
build_team.conf
. If you don’t specify a configuration
file the script will use the
build_team.conf
file in the same directory as the script. If you
have created a custom configuration file you enter that configuration file name.
-v
is optional. If you want to run the script in debug mode you add
-v
at the end of the
command.
2.
At the prompt select one of the following:
1) Create Team
2) Create Regions
3) Delete Team
4) Delete Regions
5) Add Device to Region
6) Remove Device From Region
X/x Exit
3.
If prompted enter user and password. The three controllers must have the same user name
and password.
4.
Check for messages or errors and respond to any prompts.
5.
Select
X/x
to exit the script.
