Advanced Tab Field Descriptions
The Console Management Advanced tab configures serial port options that may be required by
certain applications.
Configure the following parameters:
Authenticate User Enables/disables login/password authentication for users connecting from the
network.
Default: Disabled
Enable TCP Keep
Alive Enables a per-connection TCP keepalive feature. After the configured number
of seconds, the connection will send a gratuitous ACK to the network peer,
thus either ensuring the connection stays active OR causing a dropped
connection condition to be recognized.
This parameter needs to be used in conjunction with Monitor Connection
Status Interval parameter found in the Serial , Advanced , Advanced Settings
tab. The interval determines how long the IOLAN will wait during inactivity
before "testing" the connection. It should be noted that if a network connection
is accidentally dropped, it can take as long as the specified interval before
anyone can reconnect to the serial port.
Default: Disabled
Enable Message of
the Day (MOTD) Enables/disables the display of the message of the day.
Default: Disabled
Multisessions The number of extra network connections available on a serial port (available
only on 2 port+ models), in addition to the single session that is always
available. Enabling multisessions will permit multiple users to monitor the
same console port. Each user monitoring the port can be assigned different
privileges to this port.
Data Range: 0-7 multisessions per serial port
Default: 0
Idle Timeout Use this timer to close a connection because of inactivity. When the Idle
Timeout expires, the IOLAN will end the connection.
Default: 0 seconds so the port will never timeout
Range: 0-4294967 seconds (about 49 days)
