Using the SEHI Hub View

Device General Status

This polling interval controls how often the Hub View Front Panel Information — such as Uptime, Device Name, and so forth — and some port status information is updated.

Device Configuration

This polling interval controls how often a survey is conducted of the devices installed in your SEHI-controlled HUBStack.

Port Operational State

This polling interval controls the update of the information displayed in the Port Status boxes for each port in the device. Port state information includes link state (the color code) and admin state (on or off).

Statistics

This polling interval controls how often the information displayed in the Port Status boxes is updated when the Port Display Form is set to a rate or percentage, and how often the Device, Module, and Port statistics counts are updated.

NOTE

SPMA generates network traffic when it retrieves the above-described information; keep in mind that shorter intervals mean increased network traffic. Range limits for these polling times are 0-999,999 seconds; however, an entry of 0 will be treated as a 1.

Enabling/Disabling Ports

You can enable and disable ports both from the Module menu, which affects all ports on a single module, or device; or from the Port menu, which affects individual ports.

To enable or disable an individual port:

1. Click mouse button 1 on the Port Status box to toggle the port On or Off.

or

1.Click mouse button 3 on the Port Index or Port Status box to display the Port menu.

2.Drag down to Enable or Disable, as appropriate, and release. The selected port changes color when its state changes. A disabled port is blue.

To enable or disable all ports in a module:

1.Click mouse button 3 on the Module Index box to open the Module menu.

2.Drag down to Enable All Ports or Disable All Ports, as appropriate, and release.

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.
