Line Service Commands

netmask

The network subnet mask. For example, 255.255.0.0. If your user is authenticated by RADIUS and the RADIUS parameter Framed-Netmaskis set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here.

password

This field defines the password which is associated with the user defined by the user parameter. It is used to authenticate a user connecting to the IOLAN. You can enter a maximum of 16 alphanumeric characters.

proto-comp

This determines whether compression of the PPP Protocol field takes place on this link. The default is On.

ripaddr

The IPV4 IP address of the remote end of the PPP link. Choose an address that is part of the same network or subnetwork as the IOLAN. If you set the PPP parameter IP Address Negotiation to On, the IOLAN will ignore the remote IP address value you enter here and will allow the remote end to specify its IP address. If your user is authenticated by RADIUS and the RADIUS parameter Framed-Addressis set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here. The exception to this rule is a Framed-Addressvalue in the RADIUS file of 255.255.255.254; this value allows the IOLAN to use the remote IP address value configured here.

roaming-callback

A user can enter a telephone number that the IOLAN will use to callback him/her. This feature is particularly useful for a mobile user. Roaming callback can only work when the User Callback parameter is set to On. Roaming callback therefore overrides (fixed) User Callback.To use Roaming Callback, the remote end must be a Microsoft Windows OS that supports Microsoft’s Callback Control Protocol (CBCP). The user is allowed 30 seconds to enter a telephone number after which the IOLAN ends the call. The default is Off.

routing

Determines the routing mode (RIP, Routing Information Protocol) used on the PPP interface as one of the following options:

zNone—Disables RIP over the PPP interface.

zSend—Sends RIP over the PPP interface.

zListen—Listens for RIP over the PPP interface.

zSend and Listen—Sends RIP and listens for RIP over the PPP interface.

This is the same function as the Framed-Routingattribute for RADIUS authenticated users. Default is None.

rpassword

The rpassword is the password which is associated with the user defined by ruser. It is used to authenticate a user connecting to the IOLAN. You can enter a maximum of 16 alphanumeric characters.

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.
