Ethernet Interface Configuration

Advertised Ability (Selectable)

During auto-negotiation, the FE-100TX “tells” the device at the other end of the segment what its capabilities are. The capabilities of a port with an FE-100TX installed are 10BASE-T, 10BASE-TFD (full duplex mode), 100BASE-TX and 100BASE-TXFD (full duplex mode). In normal operation, with all capabilities enabled, the FE-100TX “advertises” that it has the ability to operate in any mode. The Network Manager may choose to set up the port so that only a portion of the available capabilities are advertised and the others are disabled. For example, only 100BASE-TX and 100BASE-TXFD might be enabled so that only devices that operate at 100 Mbps can communicate with that port. Section 5.19.4 describes how to enable or disable advertised modes.

5.19.1Configuring an FE-100FX/F3 Interface or a Port 7 or 8 FE-100FX/F3 Interface

Whether configuring the fixed interface (ports 1-6) or an FE-100FX or FE-100F3 installed in port 7 or 8, the procedure is the same. The interface port must be manually set to operate in the same technology as the device at the other end of the connected segment. Use the Desired Oper. Mode field to set the FE-100FX or FE-100F3 interface ports. This field toggles between 100BASE-FX and 100BASE-FXFD (full duplex). To set the active technology through Local Management, proceed as follows:

1.Use the arrow keys to highlight the Desired Oper. Mode field.

2.Use the SPACE bar to select 100BASE-FXor 100BASE-FXFD(full duplex).

3.Press ENTER. The port now operates in the chosen mode.

4.Use the arrow keys to highlight the SAVE command. Press ENTER. The message “SAVED OK” displays and Local Management saves the changes to memory.

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.
