5.Use the arrow keys to highlight the Errors field.

6.Use the SPACE bar to select either the ON or OFF option and press ENTER. ON forces the source module and port to forward errored frames and valid traffic to the destination module(s) and port(s). OFF forces the errored frames to be dropped before forwarding traffic.

7.Use the arrow keys to highlight the Status field.

8.Use the SPACE bar to select either the ADD or DEL (delete) option. Press ENTER. This adds or deletes the port selections made in steps 2 and 4 and also updates the screen Source Port and Destination Port list.

NOTE

If more than one port is to be redirected, repeat steps 1 through 8 for each additional setting, then go to step 9 to save all the new settings at once.

9.Use the arrow keys to highlight SAVE at the bottom of the screen. Press ENTER. The message “SAVED OK” is displayed. This saves the new settings and updates the Source Port and Destination Port read-only fields.

5.24BROADCAST SUPPRESSION SCREEN

The Broadcast Suppression screen, Figure 5-30allows the user to set a desired limit of receive broadcast frames per port per second. It also displays statistics.

NOTE

The Broadcast Suppression screen may not be available if the operational mode of the module has been set to SECURE FAST VLAN. Refer to the Release Notes to see what operational modes support Broadcast Suppression. Refer to Section 5.15.9 for instructions on configuring the operational mode of the module.

Any broadcast frames received above the desired threshold will be dropped.

To access the Broadcast Suppression screen from the Module Specific Configuration screen, use the arrow keys to highlight the BROADCAST SUPPRESSION menu item and press ENTER. The Broadcast Suppression screen displays.

6H129-08, 6H128-08 specifications

Cabletron Systems was a notable provider of networking hardware in the 1990s, specializing in solutions that enabled enterprises to build robust and scalable networks. Among their product offerings were the models 6H128-08 and 6H129-08, which were designed to meet the needs of demanding networking environments.

The 6H128-08 is an Ethernet hub that supports up to 128 ports. This model is particularly recognized for its reliability and performance in connecting numerous devices within a local area network. One of the main features of the 6H128-08 is its support for both 10BASE-T and 100BASE-TX Ethernet standards, allowing it to handle varying data transmission speeds and ensuring compatibility with older and newer devices. This dual support features made it particularly appealing for businesses transitioning from older network technologies to faster Ethernet connections.

In terms of technology, the 6H128-08 leverages a centralized architecture which reduces network collision domains. This design contributes to improved network performance by allowing simultaneous data transmission from multiple devices. The hub features a range of LEDs that provide real-time status updates on port connectivity and data transmission activity. This allows network administrators to easily monitor and troubleshoot connectivity issues.

The 6H129-08 is often paired with the 6H128-08, functioning effectively as an additional port expander or in cascading configurations. This model also supports 128 ports and offers identical compatibility with the Ethernet standards mentioned, ensuring seamless integration in larger network setups. An important characteristic of the 6H129-08 is its enhanced fault tolerance, which is vital in mission-critical environments where network downtime must be minimized.

Both models are equipped with various management features, enabling network administrators to configure settings and optimize performance easily. The ability to use SNMP for network management supports monitoring and managing the entire network from centralized software applications.

Overall, the Cabletron Systems 6H128-08 and 6H129-08 stand out for their robust performance, extensive port capabilities, and compatibility with multiple Ethernet standards, making them suitable for enterprises looking to build or expand their networking infrastructure. These products reflect Cabletron's commitment to reliability and innovation in the field of networking hardware.
