The System 2000 family of 10Base-T workgroup hubs consists of three product sets: the Model 2803/2804; the Model 2813/2814; and the Model 2813SA/2814SA. In stand-alone configurations, the Model 2803 and Model 2804 offer simple connectivity and low-level management. The Model 2813 and Model 2814 provide connectivity and a choice of Standard and Advanced agent management options. The Model 2813SA and Model 2814SA deliver connectivity and Advanced Analyzer management capabilities.
Standard Agent: The Model 2813-05 and Model 2814-05 include the Standard (formerly Basic) agent, which supports real-time hub-level and port-level management. The Standard agent delivers fault and diagnostic tools for monitoring and controlling the hubs through a manually-created network map.
The Standard agent also supports the Expanded View (TM) graphical user interface, which provides a real-time image of the hub on the management station screen. Fault, Performance and Configuration pull-down menus offer hub-level and port-level diagnostic, status and activity data. Managers can also partition and enable ports and obtain port-level performance statistics such as good packets, errors and incoming and outgoing data.
Advanced Agent: The Model 2813-04 and Model 2814-04 include the Advanced agent for mid-range to high-end network applications. The Advanced agent includes all the functionality of the Standard agent, plus advanced capabilities such as:
The Model 2813SA and Model 2814SA support up to sixteen 10Base-T host connections over unshielded twisted-pair cabling. The hubs also feature the Advanced Analyzer (TM agent, which delivers a new level of performance and expandability for particularly demanding environments.
The Advanced Analyzer agent includes all the Advanced agent capabilities, plus an integrated probe that supports highly-sophisticated network troubleshooting and problem resolution capabilities. The agent also provides full industry-standard RMON functionality that, combined with Bay Networks' embedded hub management, delivers unprecedented visibility into the network.
With the Advanced Analyzer, network managers can determine the cause of a network problem, as well as its physical port location, network address and fault and performance information. Working with Optivity, as well as Network General Corp.'s Distributed Sniffer System (DSS), the Advanced Analyzer delivers integrated troubleshooting, network design and protocol decode capabilities.
To support the Advanced Analyzer, the Model 2813SA and Model 2814SA employ a dual-interface processing architecture that dedicates a Bay Networks developed ASIC frame processing unit (FPU) for data collection throughout the hub. The architecture frees up the NIC for SNMP transactions, ensuring that SNMP communications are maintained even under extreme network load conditions. Distilled ASIC-gathered data is passed to a high-performance Motorola 32-bit 68EC040 processor for further analysis before being forwarded to the management station.
For growing network environments, the System 2000 allows up to four Model 2803s or Model 2804s to be stacked with a single Model 2813/2814 or Model 2813SA/2814SA, creating a manageable 10Base-T cluster supporting up to 80 users. In a cluster arrangement, SNMP management is extended to all hubs, enabling the entire stack to be managed from a central console. The five-hub stack also acts as a single repeater, providing configuration ease and flexibility for designing large networks.
Hubs are linked via Model 988 Expansion Cables, which serve as a virtual backbone between concentrators. An expansion cable is included with each Model 2803 and Model 2804.
The Model 2813(SA) and Model 2814(SA) include a local load capability which allows the hubs to obtain the management agent software from local memory, eliminating the requirement for a separate boot server. The local image is stored in flash EEPROM, enabling agent upgrades to be accomplished quickly and easily. The local load and Flash EEPROM features are particularly useful for small Ethernet networks operating at remote sites.
System 2000 10Base-T workgroup hubs also include the ability to communicate management data over IPX in Novell NetWare environments. The Model 2813(SA) and Model 2814(SA) include an integrated IPX agent to pass management traffic over both IP and IPX to an Optivity for NMS network management station. The IPX agent eliminates the need to administrate IP in Novell network environments.
