Configuring Users

sess-timer

The amount of time, in seconds, that the Session Timer will run. Use this timer to forcibly close a user’s session (connection). When the Session Timer expires, the IOLAN will end the connection. The default value is 0 (zero), meaning that the session timer will not expire (the session is open permanently, or until the user logs out). The maximum value is 4294967 seconds. The User Session Timer will override the Line Session Timer, with the exception of reverse SSH or reverse Telnet sessions.

port

.For outbound User Services such as Telnet, SSH, TCP clear or SSL raw, this is the target port number. The default value will change based on the type of Service selected; the most common known port numbers are used as the default values.

access-clustered-ports

When enabled, allows the user access to IOLANs that have been configured in the clustering group. The default is on.

Set User

Description Sets users settings. Normal-level users can configure only their own settings. Admin-level users can configure any users settings, including their own (with the exception of their User Level, which must stay at Admin).

Options callback

When On, enter a phone number for the IOLAN to call the user back (the Callback parameter is unrelated to the Line Dial parameter).

Note: the IOLAN will allow callback only when a user is authenticated. If the protocol over the link does not provide authentication, there will be no callback. Therefore, when the Line Service is set to PPP, you must use either PAP or CHAP, because these protocols provide authentication. The default is Off.

The IOLAN supports another type of callback, Roaming Callback, which is configurable when the Line Service is set to PPP.

SDS, MDC specifications

Perle Systems is a leading provider of connectivity solutions, renowned for its robustness and reliability in networking hardware. Among its expansive product offerings, the MDC (Multiport Device Converter) and SDS (Serial Device Server) stand out as pivotal solutions for industries requiring seamless data communication and device management.

The Perle MDC serves as a powerful multi-port device converter, providing the ability to connect multiple serial devices to a computer network without needing a separate connection for each device. This is particularly useful in environments with limited computing resources or high device density, such as railways, manufacturing plants, or remote field operations. It is designed to convert serial communication, which is commonly used in legacy devices, into Ethernet/IP or TCP/IP protocols, ensuring that older devices can integrate into modern networks.

Main features of the MDC include its robust design for industrial environments, support for a variety of serial protocols, and multiple device connections. It supports data rates of up to 115200 bps and provides easy monitoring and configuration via a web-based interface. Additionally, the MDC incorporates advanced security features including SSL and SSH encryption, ensuring data integrity and protection against unauthorized access.

On the other hand, the Perle SDS model exemplifies advanced serial device hosting capabilities, allowing users to connect Ethernet networks to serial devices. It acts as a bridge, enabling remote devices to be configured and managed over IP networks. The SDS series is known for its versatility, supporting a range of serial communication protocols, including RS-232, RS-422, and RS-485, making it suitable for various applications such as point-of-sale systems, industrial automation, and remote monitoring.

The SDS boasts several characteristics that enhance its functionality, such as automatic device discovery, real-time monitoring, and local or cloud-based management options. Its feature set also includes traffic management capabilities, allowing the optimization of device communication by controlling the flow of data, which is critical for applications requiring high reliability and low latency.

Both the MDC and SDS benefit from a strong emphasis on ease of deployment and management. They support a range of network topologies, facilitating seamless integration into existing infrastructures. Furthermore, these devices are backed by Perle Systems' reputation for customer support and a commitment to ongoing innovation, ensuring that organizations can rely on these solutions for future growth and technological advancement.
