Figure 6-4. Add MAC Address Window

d.Enter the desired MAC address in an xx:xx:xx:xx:xx:xx format, then click

on . A confirmation window will appear; if you click onYes to secure the address, it will appear in the Secure Addresses list box.

4.To secure addresses for additional ports, click to select the desired port in the Channel A Port Security window; the Addresses window will automatically display the Learned and Secure addresses for the new port.

NOTE

If the maximum number of addresses has already been assigned to the floating cache on the selected board, or if you have already secured two addresses on a non- LANVIEWSECURE hub port, the Add button will be disabled.

You can clear both Learned and Secure addresses (and re-start the learning process) by using the Reset Learned Addresses option in the repeater-, hub-, or port-level Security window; see Resetting Learned Addresses, page 6-10.

Resetting Learned Addresses

You can clear all learned and secured addresses out of a port’s address table, and allow that port to begin learning (and securing) new addresses, as follows:

1.In the Repeater Security window, click mouse button 1 on the repeater interface for which you would like to reset learned addresses.

2.Click mouse button 1 on , , or to open the appropriate window.

3.In the Module or Port window, click to select the hub(s) or port(s) for which you wish to reset learned addresses.

NOTE

You cannot reset learned addresses for any port which is already locked or in an unsecurable state (either natural or forced). If you select a group of ports which includes one in a locked or unsecurable state, or if you select a hub or a repeater which has a port in one of these states, the Reset Learned Addresses option will be unavailable.

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.
