22COREBUILDER 6000 INTELLIGENT SWITCHING SOFTWARE REVISION 8.2.0

When installing 8.2.0 Intelligent software onto a LMM+ running 8.2.1 Extended software, and non-IP VLANs are defined, you must reset non-volatile ram immediately after installing the 8.2.0 Intelligent software into flash memory. Please enter the following command immediately after the message Installation complete is displayed to the console:

system nvdata reset

When the first FDDI MAC address of an FSM is assigned to the backplane, FDDI ports are renumbered.

EFSM packet filters can access packet data through byte 64 in the packet.

When using the Administration Console to display all instances of a given MAC address in a mixed token ring and Ethernet environment, you must use the find command for both the noncanonical and canonical formats.

If you attempt to run CoreBuilder system software 8.2.0 on an LMM+ at revision 2.11 or earlier, the system fails to reboot automatically when you turn it on.

The Ethernet Switching Module (ESM) and the Token Ring Switching Module (TRSM) incorrectly report transmit filter statistics.

The ESM and TRSM FDDI packet filters cannot access packet data beyond byte 16 in the packet.

VLAN statistics are not supported on the ESM.

The ESM only supports RMON groups 1 through 4.

Known Problems The following software problems are identified at this release:

Do not create port groups and port group filters on the FESMs or FSMs.

The FESM and TMM-FE rxFrames, txFrames, rxBytes, and txBytes statistics might report inaccurate values.

The FESM FDDI MAC rxFrames, txFrames, rxBytes, and txBytes statistics might report inaccurate values.

If you attempt a warm reset, a cold reset may occur.

The system nvData save procedure fails if it occurs at the same instant when a MAC address is learned or aged out of the slot’s MAC address table.

6000 specifications

The 3Com 6000 series, launched in the late 1990s, was a significant advancement in networking technology, designed to meet the growing demands of enterprise-level networking. This series provided powerful solutions for businesses seeking reliable, efficient, and scalable networking capabilities.

At its core, the 3Com 6000 series featured a modular design, allowing companies to customize their networks according to specific needs. This flexibility meant that organizations could add or replace components as their networking requirements evolved, ensuring investment protection and a tailored approach to connectivity. The ability to scale was particularly important for businesses that anticipated growth or change in operational demands.

One of the standout features of the 3Com 6000 was its advanced switching capabilities. The series employed high-performance switching technologies that supported various protocols, including Fast Ethernet and Gigabit Ethernet. This versatility made it suitable for diverse environments, from small offices to large corporate settings. The 3Com 6000 switches were engineered to deliver high throughput and low latency, crucial for applications requiring real-time data transfer.

The series also supported a range of network management tools, enhancing operational efficiency. With SNMP (Simple Network Management Protocol) support, network administrators could easily monitor and manage network performance, troubleshoot issues, and configure devices from a centralized location. This capability significantly streamlined network operations, reducing downtime and optimizing resource allocation.

Security was another significant concern addressed by the 3Com 6000. The series incorporated robust security features, including access control lists (ACLs) and VLAN (Virtual Local Area Network) support. These features allowed network administrators to segment traffic and enforce security policies, protecting sensitive data and ensuring compliance with organizational standards.

Moreover, the 3Com 6000 series was designed with energy efficiency in mind, reflecting a growing awareness of the environmental impact of IT infrastructure. By implementing power-saving features, the series helped organizations reduce their overall energy consumption while maintaining optimal network performance.

In summary, the 3Com 6000 series stood out for its modularity, advanced switching capabilities, extensive management tools, strong security features, and energy efficiency. It represented a forward-thinking solution for enterprises aiming to build robust network infrastructures capable of supporting a wide range of applications and services. As organizations increasingly relied on networked systems, the 3Com 6000 played a crucial role in shaping the landscape of enterprise networking.
