Introduction
Features
Processor
The 9G421-02/9G429-02 is equipped with an advanced Intel i960 microprocessor. This microprocessor provides a platform for all management functions, such as Spanning Tree, RMON, and MIB support within a scalable RISC-Based architecture.
Fast Packet Switching
The 9G421-02/9G429-02 incorporates a hardware-based switch design referred to as the SmartSwitch ASIC, a collection of custom ASICs designed speciÞcally for high-speed switching.
Management
The 9G421-02/9G429-02 features SNMP for local and remote management. Local management is provided through the RS232 COM ports on the SmartSwitch 9000 Environmental Module using a standard VT220 terminal or emulator. Remote management is possible through CabletronÕs SPECTRUM or any SNMP- compliant management tool. Included as management features are the IETF Standard Management Information Base (MIBs) RMON (RFC 1271), IETF MIB II (RFC 1213), IETF Bridge MIB (RFC 1493), and a host of other Cabletron enterprise MIBs. The 9G421-02/9G429-02 also offers the user a wide variety of statistical network management information to enhance network planning and troubleshooting. This module provides information for each front panel Ethernet Gigabit port, including packet counts along with errored frame information, such as collisions, CRCs, and Giants, via a variety of industry-standard and private MIBs. Industry standard IEEE 802.1d bridging, including the Spanning Tree Algorithm, is supported.
Connectivity
The 9G421-02 has one interface to the INB and two front panel multimode Þber (MMF) cables connecting to SC connectors. The INB interface is a Þxed connection to the INB, allowing the 9G421-02 to communicate with other SmartSwitch 9000 modules supporting various LAN technologies including Token Ring, FDDI, Ethernet, WAN and ATM. Each front panel SC connector provides 1 Ethernet Gigabit connection. The 9G429-02 has one interface to the INB-B and two single mode Þber (SMF)/MMF SC connectors on the front panel of the module.
