3Com Router 5000 and Router 6000 Family

Release Notes v2.41 • Page 10

•To get ftp mputs to work properly from a client, ftp update normal must be set on the router.

3.2SNMP

•The router does not respond to SNMP when the user is logged into the System View. This causes Network Management Systems such as 3Com Router Manager and 3Com Network Director to generate errors. To resolve this, exit the System View.

•The Frame Relay MIB does not use the latest version of the RFC 2115. As a result, public MIB variables for troubleshooting Frame Relay performance problems are not supported; (e.g. frCircuitLogicalIfIndex) from the current FRAME_RELAY-DTE-MIB (RFC 2115)

•The router will send an initial invalid trap packet upon link down/up event, followed by the correct Trap packet. Ignore the first trap packet, the second packet is correct.

3.3System Management

•On RPU2s when booting from the compact flash, it is possible to get the following error on boot up: “Error encountered during checking disk, format the disk!” and the boot will not complete. Power down the router and power it back up to clear the problem.

•Analog Modem debugging shows internal activity when no cable is connected. This indicates that the modem is active and ready to receive or make calls.

•When saving a configuration to a non-existing directory the following message displays: “Cannot open the configuration file, this may be caused by insufficient memory space”. This is an incorrect message and is displayed when the user is trying to save a file to a non- existent directory. To solve the problem, create the directory first.

•When rebooting the router, the Current Configuration change detection sometimes detects changes when there were none, and a warning message is displayed.

•There is no way to recover if both the Bootrom password and the console password are lost. If both passwords are lost, the router must be returned to 3Com for repair (RMA).

•FTP user cannot be cleared; set the ftp time-out to 1 minute to clear an inactive session rather than waiting the 30 minutes set by default.

•The display current-configuration command with a filter will not recognize the underscore character(”_”) alone. Use the backslash character (”\”) in front of the underscore to get the desired result. For example, display current-configuration begin bgp\_peer will display the configuration starting with the line containing “bgp_peer”

•CPU Usage history graph has the time scale backwards; the right side is the most recent history.

•A 1-Port Channelized E3 MIM card will not operate if inserted in slot 0 on the 5642 or slot 1 on the 5232. Select a different slot for the E3.

3.4Interface Management

•When the Dialer interfaces toggles state (up or down), minor packet loss will occur for any packet passing through the router.

•Interface statistics with a flow-interval of under 10 seconds are not accurate. Do not enter flow- interval values under 10 seconds.

•The Virtual-Ethernet interface protocol state displays as being down when running PPPoE. This is the normal operating state of the Virtual-Ethernet interface.

5000, 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.
