Figure 6-2. Channel A Port Security Window

The top portion of the window contains a list box which displays each port communicating on the selected channel, designated by hub and port number. Each port’s current Lock Status, violation response, Security Level, and Trap status is also displayed. Note that any ports on a non-LANVIEWSECUREhub will display “not applicable” in the Security Level field; eavesdropper protection (scrambling) and continuous lock mode cannot be implemented for these ports. (See Security on Non-LANVIEWsecure Hubs, page 6-5, for more information.)

The lower portion of the window provides the fields you need to configure security for one or more of the listed ports. Note that if you select a group of ports with different security capabilities, only those capabilities which apply to every port in the selected group will be active; those which are not available for every port in the selected group will be grayed out.

To configure security levels and violation response:

1.Use the Set Security For field or the mouse to select the port or ports for which you wish to configure security (note that the settings in theSet Security For field will change automatically as you click to select or de-select ports).

2.In the On Violation field, click to selectdisable if you want the port or ports to be disabled if any unauthorized source address is detected, or select noDisable if you wish the port to remain operational after a violation. Note that selecting the noDisable option effectively removes intruder protection

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.
