	the event that the IOLAN loses communication to the primary host. The
	IOLAN will first establish a connection to the primary host. Should the
	connection to the primary host be lost (or never established), the IOLAN will
	establish a connection the backup host. Once connected to the backup, the
	IOLAN will attempt to re-establish a connection to the Primary host, once this
	is successfully done, it gracefully shuts down the backup connection.
	Default: Disabled
Primary Host	Specify a preconfigured host that the serial device will communicate to through
	the IOLAN.
	Default: None
TCP Port	Specify the TCP port that the IOLAN will use to communicate to the Primary
	Host.

Backup Host	Specify a preconfigured host that the serial device will communicate to through
	the IOLAN if the IOLAN cannot communicate with the Primary Host.
	Default: None

When you click the Add or Edit button, the Host Entry window appears. The hosts in the multihost list must already be defined (see Host Table on page 98 to learn how to create a host). If you add a host that was defined with its fully qualified domain name (FQDN), it must be resolvable by your configured DNS server.

Configure the following parameters:

Host Name	Specify the preconfigured host that will be in the multihost list.
