Add High Availability backup
Fill in the fields, then click OK to activate high availability.
- 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.
- Both (mutual high availability feature): if the backup machine detects that the active machine has
failed, it will take over and begin load balancing. At that point the statuses of the two machines are
reversed, the backup machine becomes the active and the primary becomes the standby.
- 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.
- Heartbeat source address
- The address of the high availability partner machine that sends
heartbeats. This address should be defined on the physical adapter of the partner that you wish
to use to monitor the health of the Load Balancer. You can define a source address for each physical
adapter in the Load Balancer machine.
- Heartbeat destination address
- The destination address is the address of the high availability partner machine
to which heartbeats and responses are sent. This address should be defined on the physical
adapter of the partner that you wish to use to monitor the health of the Load Balancer. You can
define a destination address for each physical adapter in the Load Balancer machine.
