Add High Availability backup

Fill in the fields, then click OK to activate high availability.
Note: Ensure that both Load Balancer machines are running the same version. Do not add a backup Load Balancer machine that is running a different version of Load Balancer from the version that is installed on the primary Load Balancer machine.

Port number
The number of a port that is unused on both Load Balancer machines that will be used for heartbeat messages. You must use the same port number for both the primary and backup machines.

Role
Choose between:
  • Primary: the primary machine sends connection data continually to the backup machine.
  • Backup: the backup machine is in standby state, continually updated and ready to take over if necessary.

Recovery strategy
Choose between:
  • Auto--the primary machine resumes load balancing as soon as it comes back into service.
  • Manual--the primary machine acts as standby for the backup machine and does not resume routing packets until the administrator issues a takeover command.
