Adding/Editing a Multihost Entry
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:
When this option is enabled, you can define up to 49 hosts that the serial device
connected to this serial port will attempt communicate to. With this mode of
operation, the IOLAN will connect to multiple hosts simultaneously.
Default: Enabled
Click the Add button to add a host to the list of hosts that will be receiving
communication from the serial device connected to the IOLAN.
Highlight an existing host and click the Edit button to edit a host in the list of
hosts that will be receiving communication from the serial device connected to
the IOLAN.
Click the Delete button to delete a host to the list of hosts that will be receiving
communication from the serial device connected to the IOLAN.
When this option is enabled, you need to define a primary host that the serial
device connected to this serial port will communicate to and a backup host, in
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
Specify a preconfigured host that the serial device will communicate to through
the IOLAN.
Default: None
Specify the TCP port that the IOLAN will use to communicate to the Primary
Host .
Default: 0
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
Specify the TCP port that the IOLAN will use to communicate to the Backup
Host .
Default: 10000
Host Name Specify the preconfigured host that will be in the multihost list.
Default: None
