Technical Overview

INB Interface

Each module attaches to both INB A and INB B and has two INB ASICs. The INB ASICs use 64-byte Ethernet frames for transmission onto the INBs at 66 MHz.

The 9X5XX modules are fully compatible with the the first generation 9X4XX modules. The first generation modules communicate only on INB B using a

56-byte canonical frame format, at 40 MHz. If the newer module detects a first generation module on the backplane, it automatically changes from the fast

66 MHz Ethernet frames, to the first generation compatible 40 MHz canonical frame on INB B only. INB A is used only by the 9X5XX modules and remains at the higher speed.

i960 Core

The i960 core provides modules host services, the SNMP protocol stacks, to support industry standard MIBs, as well as Cabletron enterprise extension MIBs for each media type. Management services, such as telnet, WebView and network address to MAC address mapping, are also provided by the i960 core.
