5.3. Setup Heartbeat Channels

The IP address information for this interface, in the format of 'IP address':'subnet mask':'broadcast address'. The broadcast address is optional. The standby cluster will set to this IP address. You should make sure this IP address is available. This is not required for heartbeat communication, but many of the other modules such as SMA, IP Monitoring, required an IP address, you should better give an IP address to it.

The heartbeat interval of this channel in milli seconds. If this is empty, the global default value will be used.

Timeout value of this heartbeat channel in seconds, that means if not receiving heartbeat within this period, this channel will be treat as dead. If this is empty, the global default value will be used.

If a critical channel failed, the standby cluster will failover even the number of alive channels is above the minimal required value.

To disable this channel. It is useful for temporary disable a channel, but the configuration will still be keep, and can be re-enabled afterward.

Set the baud rate of this serial channel, default is 9600. You may want to set to a higher baud rate to enable faster heartbeat communication. Setting to an inappropriate or unsupported value will cause serial heartbeat to failure. Please refer to the serial port specifications of your hardware manufacturer.

The device of this serial channel, e.g. /dev/ttyS0. This is required, and you should make sure the device exists and is valid.

The heartbeat interval of this channel in milli seconds. If this is empty, the global default value will be used.

Timeout value of this heartbeat channel in seconds. If this is empty, the global default value will be used.

If a critical channel failed, the standby cluster will takeover the active cluster.

To disable this channel. It is useful for temporary disable a channel, but the configuration will still be keep, and can be re-enabled afterward.
