NetView Management

The SmartSwitch 1800 supports a NetView service point function, which allows a node to be configured and managed from a NetView host. NetView support provides management access to downstream SDLC devices, and allows diagnosing problems and changing parameters in the node.

The service point in the SmartSwitch 1800 connects to the NetView host via an LLC2 session (over LAN or frame relay), which is established at node IPL. LLC2 must be installed in either the service point node or another SmartSwitch 1800 that is con- nected to the service point node via X.25 (physical link or over frame relay per Annex G or RFC 1490). (The link can be between two nodes of any type among SmartSwitch 1800, 9W004, FRX4000, and FRX6000.)

The NetView host (also referred to as a focal point) sends commands to the service point in the form of NMVTs (network management vector transports). The service point function translates information from the node into NMVTs and responds to the host. Four types of NMVTs can be transmitted:

●RUNCMDs – commands from the host to execute specified operations. Three types of command are supported:

◆Display – used to display status and configuration information

◆Vary – used to change the active/inactive status of a PU or line.

◆Modify – used to change configuration of a PU and the line between it and the node.

●RUNCMD replies – from the service point to the host.

●Alerts – unsolicited information about events in the node, lines, or PUs.

●LPDAs – link problem determination aids, which are procedures used to test status and to control the node, communications line, and PU interface.

The SmartSwitch 1800 supports LPDA versions 1 and 2.

The actual command syntax used in NMVTs from the host is documented in IBM’s VTAM Operation manual. Responses to host commands generally use the textual characteristics of VTAM (with a different prefix).

1800 specifications

Cabletron Systems, a leading player in network management and telecommunications solutions during the late 20th century, introduced several innovative products that played a crucial role in shaping enterprise networking. Among these were the Cabletron FRX6000, FRX4000, and the FRX1800, which delivered advanced features aimed at enhancing network performance, security, and scalability.

The Cabletron FRX6000 was designed as a robust multi-layer switch, ideal for large-scale enterprise environments. It supported extensive routing capabilities, allowing organizations to manage traffic efficiently even under heavy loads. The FRX6000 boasted high throughput rates and low latency, making it suitable for demanding applications. With support for various network protocols, including IP, IPX, and AppleTalk, its adaptability made it a versatile choice for diverse networking needs. Moreover, security features like VLAN support and Access Control Lists (ACLs) provided enhanced protection against potential threats.

Moving to the FRX4000, this model offered a balance between performance and cost-effectiveness. The FRX4000 maintained many of the essential features of its larger counterpart while catering to medium-sized enterprises. It provided Layer 3 routing and could handle multiple simultaneous connections, ensuring seamless communication across departments. The modular design allowed for easy upgrades, enabling businesses to expand their network infrastructure without significant overhauls. This made the FRX4000 an attractive option for organizations looking to optimize their network investments.

Lastly, the FRX1800, designed for small to medium businesses, focused on simplicity and ease of use while still incorporating powerful network management capabilities. Its user-friendly interface made it accessible for organizations lacking extensive IT resources. The FRX1800 provided essential functionalities such as Integrated Layer 2 switching and routing, network monitoring, and basic security features, ensuring that even smaller companies could maintain efficient, reliable networking without overwhelming complexity.

All three models utilized advanced technologies, including a high bandwidth backbone and state-of-the-art switching architecture, to enable fast and reliable data transfer. They also supported Quality of Service (QoS) mechanisms, allowing businesses to prioritize critical applications and ensure consistent performance across the network.

In summary, the Cabletron FRX6000, FRX4000, and FRX1800 were pivotal in enhancing network capabilities, providing organizations with scalable, secure, and high-performance options tailored to their specific needs.
