Introduction
The 9E106-06 is a multi-port Ethernet Switch Module for the SmartSwitch 9000
that provides high speed IEEE 802.1D compliant bridging and SecureFast™
Switching (SFS).
Each 9E106-06 is equipped with two advanced Intel i960
®
RISC microprocessors.
One processor provides the module’s SNMP protocol stack for both IETF and
Enterprise MIB extensions. Additional higher-level management services such as
RMON and Distributed LAN Monitor (DLM) are also provided. The other
processor acts as the primary switching device, continually directing network
traffic to the appropriate destination interface.
The 9E106-06 module provides six user configurable front panel Ethernet Port
Interfaces Module (EPIM) connections and one backplane connection to the
SmartSwitch 9000 Flexible Network Bus (FNB). The FNB is a dual FDDI
backplane channel that allows for reliable, high-capacity communications
between all FNB modules. Users on all six Ethernet segments can access the hub’s
Flexible Network Bus (FNB) and communicate with users on any other FNB
based Ethernet, Token Ring, FDDI, ATM or WAN module. Since each FNB
module translates its native user’s data packets to FDDI frames, all modules can
communicate without the use of any external or additional bridge or router
components.
Each EPIM Port is a single network segment that can operate in one of two ways:
as a host to a single user or as a host to multiple users through another multiport
switch, bridge, or repeater device. Ethernet networks are connected to the
9E106-06 using standard Cabletron EPIMs.
The 9E106-06 also features front panel LANVIEW™ Diagnostic LEDs to offer
at-a-glance status information about each front panel port, as well as the
operation of the overall module.
