Configuring Port Operation

You can configure 10/100 ports on the base unit for operational parameters such as enabled/disabled, and port speed or auto-sensing.

To configure port operation, do the following:

1.Select Port Configuration from the Main Menu.

2.Select Administrative Status Control from the Port Configuration menu.

3.Select Port Group 1-12, 13-24 or Switch/Media Module.

4.Highlight any port, and select “Enabled” or “Disabled” in the Admin State field to toggle between enabling and disabling the port(s).

5.Select “Force 10,” “Force 100” or “Auto” under the Mode field to set the port speed to 10 Mbps, 100 Mbps or auto-detection.

The console interface can only enable/disable the ports on switch/media modules. To configure the speed/mode, use the 100Full/Auto toggle switch on the 10Base-T/100Base-TX module or the Full/Half toggle switch on the 100Base-FX module.

Spanning Tree

The Switch/Media modules do not support Spanning Tree, which is intended to prevent network loops from forming. There is no loop detection.

The user is cautioned to understand and avoid configurations that can create a loop. However, if the ELH100-12/24TX is connected in a redundant link configuration to a single device which does support Spanning Tree, one link will be properly blocked, preventing a network loop from forming. This method can be used to provide a standby connection to the network backbone which will become active if the primary link is lost.

Setting a Default Gateway

The Default Gateway parameter defines the IP address of a router or other network device which is on the same subnet as the hub. The gateway receives IP packets that are to be sent to another subnet.

To set a default gateway, do the following:

1.Select System Configuration Menu from the Main Menu.

3.Enter the gateway IP address under New Setting. Select <APPLY>.

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.
