Cabletron Systems EMM-E6 Ethernet manual I960 Processor Design, Ieee 802.1d Compliant

EMM-E6 FEATURES

i960 Processor Design

The EMM-E6 is equipped with an advanced Intel i960 microprocessor that provides a scalable RISC-based architecture.

IEEE 802.1d Compliant

The EMM-E6 is a fully IEEE 802.1d compliant Ethernet bridge. The EMM-E6 supports both the IEEE and DEC Spanning Tree algorithms, allowing it to operate in several fault-tolerant bridging environments.

Available Routing Services

Cabletron’s own routing services for the EMM-E6 are available as a software upgrade. When properly configured with the software upgrade, the EMM-E6 is capable of routing IP, IPX, DECnet, AppleTalk, and OSPF.

Special Filtering Database

The EMM-E6 supports a special filtering database which allows packets to be blocked from crossing the bridge based on manager-defined parameters.

Six Port Ethernet Bridge

The EMM-E6 has six Ethernet ports. Three of these ports (Ethernet Channels A, B, and C) operate within the hub. One other port (Ethernet Channel D) provides an external connection through one of two Ethernet Port Interface Modules (EPIMs) located on the EMM-E6 faceplate. The remaining two ports (Ethernet Channels E and F) are externally accessible through the use of Cabletron Bridge/Router Interface Modules (BRIMs), which can be configured in the module.

Integrated BRIM Technology

In addition to Ethernet Channels A through D, the EMM-E6 provides management for up to two optional Bridge/Router Interface Modules (BRIMs). These modules allow for additional Ethernet connections or Fiber Distributed Data Interface (FDDI) network backbones. The following lists optional BRIMs:

NOTE

For current information on the available BRIM modules supported by the EMM-E6, please refer to the Release Notes shipped with the module or contact Cabletron Systems.
