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.
