Introduction
The 9M426-02 SmartSwitch Module shown in Figure 1-1, is a three port switch module with two front panel HSIM interfaces and one INB-2 backplane interface. With the proper HSIM, this module may be used as an ATM uplink for the SmartSwitch 9000 chassis.
Features
Processor
The 9M426-02 is equipped with an advanced Intel i960 microprocessor. This microprocessor provides a platform for all management functions within a scalable RISC-based architecture.
Packet Switch Engine
The 9M426-02 module incorporates the SmartSwitch ASIC, a collection of custom ASlCs designed specifically for high speed switching. The SmartSwitch ASIC bus is 64 bits wide with a bandwidth of 320 Mbps. Since all frame translation, address lookups, and forwarding decisions are performed in hardware, the 9M426-02 can obtain a throughput performance of greater than 750K pps.
Management
The 9M426-02 module supports SNMP for local and remote management. Local management is provided through the RS-232 Com ports on the SmartSwitch 9000 Environmental Module using a standard VT-220 terminal or emulator. Remote management is possible through Cabletron’s SPECTRUM or any SNMP compliant management tool as well as telneting to the module. Management features including module MAC placement, front panel/FNB configuration, and SMT statistics. Switching statistics on both HSIM interfaces provide frames filtered, frames forwarded, and all Spanning Tree Protocol parameters. The 9M426-02 module supports the IETF MIB ll (RFC-1213), IETF BRIDGE MIB (RFC-1493), and a host of Cabletron enterprise MIBs. In addition, the front panel provides LEDs for transmit and receive activity.
