3Com Router 5000 and Router 6000 Family

Release Notes v2.41 • Page 7

•Frame Relay Classes that contain Frame Relay QoS parameters can be applied to PVCs even though Frame Relay Traffic Shaping is not enabled. Frame Relay Traffic Shaping must be enabled for PVC queues to be functional.

•When IPSec policies are configured on both the incoming and outgoing interfaces, one of the interfaces needs to have IPSec over GRE configured to allow multicast IP fragments to pass through the router without problems.

• The ability to add inline comments to describe an ACL as a whole is available, however the ability to add a specific description to a rule is not available. Example: if an ACL is long and complicated, inline comments for the rule cannot be added. Save the current configuration and then edit in descriptive comments to that configuration.

•FDL and remote loop back issues.

•B8ZS and ESF issues.

•LBO range issues.

•Alarm Threshold Settings issues.

•Issues with viewing current alarms and error registers.

•Various issues with local, payload, and remote loopbacks.

•DEBUG commands on the serial interface and physical layer characteristics of the router modules.

•UNDO of the DEBUG function.

•Constant DEBUG output issues on the FT1 SIC module.

•No indication of resetting (zeroing) traffic statistics.

•Lack of input and output rates displayed in bits per second as part of traffic statistics output.

•A logging error where VPN information is logged erroneously, when there was no actual VPN configuration.

•Only one system user at a time able to access the console.

•With the display interface command, packet flow shows double that of the Ethernet interfaces.

•Inaccurate display information with ACL statistics, not properly incrementing for permit statements.

•Frame Relay statistics discrepancies on the sub-interface packet counts.

•Statistics on the FT1 and T1 interfaces not properly zeroed upon reset command, “reset counter interface”.

•Banner information is lost upon FTP or TFTP while obtaining router information.

•A packet loss problem with small packet sizes configured.

•No display of trap settings with status.

•NAT traversal is not compatible with Cisco routers. IPsec tunnel is not established with Cisco routers when a NAT device is in the path.

•Only one security association is used for all traffic flows. IPsec SA is not flow based. IPSec SAs originated from 3COM routers will be ACL based. To obtain flow-based functionality, create multiple ACLs with one rule each.

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.
