This section describes the hardware characteristics of Fore's ATM switches in some detail as they form the basis for the network element model of the Fore-Switch-MIB. The correspondence between Fore's and the INMS network element model is explained when appropriate. The current version of the Fore Technology Adapter supports autodiscovery and monitoring of five types of Fore ATM switch: the ASX-200WG switch for LAN workgroups, and the four models designed for LAN backbone and LAN/WAN internetworking: ASX-200BX, ASX-1000, ASX-1200 and ASX-4000. Since the logical model of a switch is maintained by the different physical configurations, the Fore-Switch-MIB applies to all switch types.
