This MIB reports information about the protocols and network interfaces supported on the agent itself, as well as other general information. The MIB is divided into a number of groups, each of which corresponds to a specific protocol or set of information. Some groups are defined in other RFC documents.

The groups specifically defined in RFC 1213 and supported by the ELH100-12/24TX hub system software are as follows:

System – General information about the agent system

Interfaces – Information about the network interfaces of the system

Address Translation – Interface address information, both MAC level and network (IP) level

IP – Statistics and information related to the IP protocol

ICMP – Statistics and information related to the ICMP protocol

TCP – Statistics and information related to the TCP protocol

UDP – Statistics and information related to the UDP protocol

Transmission – Statistics and information related to the physical network medium to which the system interfaces (e.g. Ethernet, token ring, etc.).

SNMP – Statistics and information related to the SNMP protocol

RFC 2108 (Multi-segment Repeater)

RFC 2108 provides management and monitoring for multi-segment repeaters. This group provides a set of managed objects for devices (repeaters, MAUs, interfaces) that conform to the IEEE 802.3 standard for Ethernet.

RFC 1643 (Ethernet-like)

RFC 1643 provides management and monitoring for the Ethernet-specific aspects of each segment on the hub. Instances of these object types represent attributes of an interface to an Ethernet-like communications medium.

RFC 1757 (RMON MIB)

RFC 1757 is a group defined under MIB-II. This MIB provides management for the RMON aspects of the hub. The ELH100-12/24TX hub supports four of the nine groups of RMON defined for Ethernet networks on a per segment basis. For further information, see the subsection “RMON” in Chapter 1 or “RMON Browser” in Chapter 5.

Cabletron Proprietary MIB Extensions

Areas of ELH100-12/24TX hub functionality not covered by the standard RFC MIBs are specified in the Cabletron private MIB. This MIB definition is specified separately from MIB-II. Areas covered in this MIB include various system, hub, and port level information.

ELH100 specifications

The Cabletron Systems ELH100 is a robust and innovative networking device that was designed for use in high-performance network environments. Introduced during the late 1990s, the ELH100 served as a valuable solution for enterprises looking to enhance their network efficiency and reliability. This device is particularly notable for its combination of advanced features, cutting-edge technologies, and versatile characteristics.

One of the main features of the ELH100 is its ability to support multiple Ethernet standards, including 10BASE-T and 100BASE-TX, making it highly flexible for diverse networking needs. This multi-standard support provided businesses with the ability to upgrade their networking infrastructure without entirely replacing existing equipment, allowing for a more cost-effective transition to higher-speed connections.

The ELH100 is equipped with a variety of ports, enabling it to connect to various devices seamlessly. Its design includes multiple media access control (MAC) addresses and the capability of supporting a sizable number of simultaneous connections. This design ensures optimal performance, even in environments requiring high data throughput.

In terms of technology, the ELH100 utilizes a pioneering architecture for load balancing and traffic management. This technology ensures that network bandwidth is used efficiently, minimizing bottlenecks and latency while maximizing throughput. Additionally, the device features hardware-based switching, which accelerates data transmission within the network, providing a competitive edge in applications that demand high-speed access.

Another defining characteristic of the ELH100 is its management capabilities. The device supports remote management via simple network management protocol (SNMP), allowing network administrators to monitor performance, configure settings, and troubleshoot issues from a central location. Such features not only enhance usability but also contribute to improved network uptime.

The ELH100 also emphasizes security features, including VLAN support, which permits the segmentation of network traffic. This capability helps in isolating different segments of the network, increasing both performance and security by preventing unauthorized access to sensitive data.

In summary, the Cabletron Systems ELH100 is a noteworthy networking solution that amalgamates versatility, efficiency, and advanced technology, making it a mainstay in the networking devices market during the era of its popularity. Its multi-standard support, hardware-based switching, management features, and security protocols underscore its capability to meet the evolving demands of enterprise networking environments.
