Identifies the Dispatcher machine that has a primary role.
Identifies the Dispatcher machine that has a backup role.
Specifies an automatic recovery strategy, in which the primary machine will resume routing packets as soon as it comes back into service.
Specifies a manual recovery strategy, in which the primary machine does not resume routing packets until the administrator issues a takeover command.
Removes this machine from high availability, so that it will no longer be used as a backup or primary machine.
An unused TCP port on both machines, to be used by Dispatcher for its heartbeat messages. The port must be the same for both the primary and backup machines.
Source address. The address (IP or symbolic) of this Dispatcher machine.
Destination address. The address (IP or symbolic) of the other Dispatcher machine.
Removes the address pair from the heartbeat information. You can specify either the destination or source address of the heartbeat pair. The address (IP or symbolic) of either the destination or the source.
Adds a target address for the reach advisor. address is the IP address, format or symbolic, of the target node.
Removes a target address from the reach advisor. address is the IP address, format or symbolic, of the target node.
The takeover address value is optional. It should only be used when the role of the machine is both primary and backup (mutual high availability configuration). The address specified is the NFA of the Dispatcher machine which normally routes this cluster's traffic. When there is a takeover of both clusters, specify the Dispatcher's own NFA address.
