EMM-E6 FEATURES
EMM-E6 User’s Guide 1-5
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:
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.
