Viewing Hub Statistics

To view hub statistics, do the following:

1. Select Hub Statistics from the Main Menu.

The screen lists the main statistical counts for both segments on the hub simultaneously.

2.Select <DETAIL> from the Hub Statistics Overview screen.

The screen lists a summary of sum total statistics for all ports on the hub.

3.Select Port Statistics from the Main Menu.

4.Enter the Hub ID and Port ID. Select <OK>.

The screen lists expanded port-level statistics for an individual port.

5.On any of the statistics screens, select <RESET COUNTERS> to clear (zero) the displayed statistical counts and <REFRESH STATISTICS> to refresh (update) the displayed statistical counts.

Downloading a Software Upgrade

You can upgrade the operational software in the ELH100-12/24TX hub without physically opening the hub or being in the same location. The software storage sector in the flash memory of the hub is reprogrammable, allowing you to easily download software feature enhancements and problem fixes to the hub from a local or remote location.

Software can be downloaded to the hub in two ways:

Via the serial port. This procedure is an out-of-band operation that copies the software through the serial port to the hub. This operation takes approximately 40 minutes and requires minimal configuration.

Via TFTP download. This procedure uses a TFTP server connected to the network and downloads the software using the TFTP protocol. A TFTP download is much faster than a serial download, requiring only a matter of minutes, and can be used to upgrade an ELH100-12/ 24TX hub that is not physically proximate. The disadvantage is that this method requires a TFTP server and additional setup.

Downloading Via the Serial Port

A serial download is the easiest method to upgrade the ELH100-12/24TX hub software, requiring the least amount of equipment and configuration.

To download hub software via the serial port, do the following:

1.Select XMODEM Download from the Main Menu.

2.Select “Upgrade FLASH and reboot.”

3.Select <Start XMODEM Download>.

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.
