SEHI MIB Structure

community names; the Chassis MGR community names are the same as those assigned via Local Management.

SEHI LIM

The SEHI LIM, or Local Management, component contains the objects that provide out-of-band management via the Console port on the SEHI’s front panel. No objects from this component are used for remote management.

Repeater One

The Repeater MIB component controls all repeater functionality on the SEHI. These functions include port count, port enable/disable, port status, board number, repeater statistics (packets, bytes, collisions, errors, etc.), protocol counts, and frame sizes; also included are the alarm, redundancy, source addressing, and trap functions. Note that the default community names for the Repeater MIB component will always be different from the default names assigned to all the other components.

SEHI Host Services

The Host Services MIB component contains the objects that provide the SEHI with its IP functionality — essentially, those functions which allow the SEHI to operate over a network — including functions such as ping, Telnet, and TFTP.

SEHI IP Services

The IP Services MIB component is not currently used by the SEHI, but is reserved for future use.

A Brief Word About MIB Components and Community Names

In the original version of the component MIB architecture, each MIB component is protected by its own set of user-configurable Read-Only, Read/Write, and Super- User community names. These names determine the level of access that will be granted to the information controlled by each individual component. For these devices, the central point of access for remote management is provided by the Chassis MGR MIB component — that is, if you define your device icon or launch a management application using the read-only, read/write, or super-user community name assigned to the Chassis MGR MIB component, your SPMA application is granted the appropriate level of access (read-only, read/write, or super-user) to all of that device’s MIB information — even if the other MIB components have different community names (as will occur of necessity with the SEHI’s multiple Network MIB components, each of which must have a unique set of community names).

NOTE

The set of community names you assign via Local Management are those which apply to the Chassis MGR MIB component.

SEHI-22/24, SEHI-32/34 specifications

Cabletron Systems was a notable player in the networking hardware market during the rise of local area networks (LANs) in the late 20th century. Among its innovative products were the SEHI-22/24 and SEHI-32/34 modules, which were designed to enhance network capabilities in enterprise environments.

The SEHI-22/24 and SEHI-32/34 were versatile high-performance Ethernet switch modules that offered significant advantages in network management and connectivity. These modules were designed to work with Cabletron's modular switching and routing architecture, allowing for scalable solutions tailored to specific network demands. A key feature of the SEHI series was its support for a range of Ethernet standards, ensuring compatibility with diverse networking environments.

One notable characteristic of the SEHI-22/24 was its ability to support both 10Base-T and 100Base-TX Ethernet technologies. This dual support enabled organizations to leverage existing 10 Mbps infrastructure while facilitating upgrades to 100 Mbps speeds without needing a complete overhaul of the network. Similarly, the SEHI-32/34 offered even greater connectivity options, accommodating more users and devices while maintaining high throughput and low latency.

In terms of management features, the SEHI series was equipped with extensive traffic management capabilities, including Quality of Service (QoS) features that prioritized bandwidth for critical applications. This ensured that essential services such as voice over IP (VoIP) and video conferencing could function optimally, even during heavy network loads.

Furthermore, both modules featured advanced diagnostics and monitoring tools that provided network administrators with critical insights into traffic patterns and potential bottlenecks. This functionality was essential for maintaining network health and optimizing performance, especially in dynamic business environments.

Security also played a crucial role in the design of the SEHI-22/24 and SEHI-32/34. The modules incorporated support for various authentication methods and access controls, ensuring that sensitive data remained protected within the corporate network.

In summary, Cabletron Systems’ SEHI-22/24 and SEHI-32/34 offered significant advancements in Ethernet switching technology, allowing organizations to build robust, scalable, and secure networks. With their impressive features, compatibility, and capacity for management and security, these modules were instrumental in shaping reliable networking solutions for enterprises navigating the rapidly evolving digital landscape.
