5.Press YES and the message “CLEARING NVRAM. REBOOT IN PROGRESS...” displays.

The 6H12X-08 will clear NVRAM and reboot. All user-entered parameters default to factory settings.

5.15.13 Enabling/Disabling IP Fragmentation

To enable or disable IP fragmentation, proceed as follows:

If the 6H12X-08 is being bridged to an FDDI ring, do not

!disable IP Fragmentation. If IP Fragmentation is disabled, all

CAUTION

FDDI frames that exceed the maximum Ethernet frame size will

 

 

be discarded.

1.Use the arrow keys to highlight the IP Fragmentation field.

2.Press the SPACE bar to choose either ENABLED or DISABLED.

3.Use the arrow keys to highlight the SAVE command.

4.Press ENTER. The Event Message Line at the top of the screen displays “SAVED OK”.

5.16SNMP COMMUNITY NAMES SCREEN

The SNMP Community Names menu item allows the user to set Local/Remote Management community names. Community names act as passwords to Local/Remote Management and are agents of security access to the 6H12X-08. Access to the 6H12X-08 is controlled by setting any of three different levels of security authorization (read-only, read-write, and super-user).

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.
