Source Addressing

2.Click mouse button 1 on ; the Channel X Source Address List window, Figure 5-2(page 5-3), will appear.

3.In the Hash Type field, click mouse button 1 on the appropriate selection to apply Dec or nonDec hashing to all ports on the selected repeater channel.

4.Click mouse button 1 on to save your changes; click on

to exit the window.

NOTE

If your SEHI firmware does not support the Hash Type feature, this field will be unavailable.

Locking Source Addresses

When Source Address Locking is enabled, it puts into place a number of security measures designed to protect your Stack from unauthorized access. Depending on the revision of firmware installed on your SEHI and the kinds of Modules in the STACK, locking ports can provide a number of different protections, including secure address assignment, trunk port locking, configurable violation response, both eavesdrop and intruder protection, multi-level locking modes, and new definitions for station and trunk ports: station ports are those detecting zero, one, or two source addresses; trunk ports are those detecting three or more.

Enabling port locking from the Source Address List window activates all applicable security protections, as configured via the Security application (described in Chapter 5 of this guide).

NOTE

Since the multi-level locking feature cannot be implemented from the Source Address List window, locking ports from this window will apply Full lock status by default to any ports which are currently unlocked. Any ports which are already in Continuous lock mode, however, will remain so. For more information on these lock modes and other security features, see Chapter 5, Security.

To enable or disable Source Address Locking:

1.Click mouse button 1 on the appropriate option in the Source Address Lock field.

2.Click mouse button 1 on to set your new lock status.

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.
