7.2 Team management
Each controller belonging to a team is a team member. To centralize team management and control, one controller is designated as the team leader. Teaming is configured on one controller and is automatically propagated to the other controllers in the team, regardless of which controller becomes the team leader.
Once a team is configured, the configuration and monitoring of team members and their associated OpenFlow switches is performed by the team leader. If the team leader goes down, another active controller becomes the team leader. If a team leader fails and then recovers, it resumes operation as only a team member.
7.3Requirements for controller teams
•Team size: 3 controllers.
•All controllers in a team must be running the same software version.
•A team requires one IP address for each controller, plus one IP address assigned to the team. If the current team leader goes down, the failover process includes keeping the team IP address active on the new team leader.
NOTE: The IP address for each team member, including the team leader, is the IP address of the machine on which each controller is configured. The team IP address is a separate address determined by the Administrator.
Ensure that route configuration in the controller domain enables the controller team IP address to be reached from all areas of the domain.
7.4 Configuring a controller team
In the HP VAN SDN Controller, teaming is configured using the REST API. This section describes configuring a controller team using cURL commands.
7.4.1Team configuration prerequisites
1.Install and start three standalone HP VAN SDN Controllers in the network. (See the latest HP VAN SDN Controller Installation Guide.)
2.Optional: To improve security, you can change the username and password from the default settings on each of the standalone controllers in step 1.
3.Select any one of the controllers to use for configuring the team.
4.On the selected controller, acquire an Authentication Token. Use the following cURL command, with the controller IP address, to acquire the token:
curl
CAUTION: Credential information (user name, password, domain, and authentication tokens) used in cURL commands may be saved in the command history. For security reasons, HP recommends that you disable command history prior to executing commands containing credential information.
