DEC GigaSwitch
Management Module Guide

Chapter 1
Introduction

What Is in This Chapter
This chapter describes the SPECTRUM Management Module for the DEC
GigaSwitch. It also provides the model type names assigned to the DEC
GigaSwitch in SPECTRUM. The model type name refers to the template used
to specify attributes, actions, and associations for device models in
SPECTRUM.

DEC GigaSwitch Management Module
The DEC GigaSwitch Management Module supports all DEC GigaSwitch
device models managed through the SNMP advanced network management
agent. SPECTRUM bases its management of these devices on the
Management Information Base (MIB), which comes as part of the
management module. The SPECTRUM model type name of the DEC
GigaSwitch device is as follows:
DECGigaSwitch: A DEC GigaSwitch data switch. SPECTRUM supports the
Fiber GIGAswitch/FDDI System Linecard, 2-port (FGL-2), Switch Control
Processor (SCP), and Clock cards. The DEC GigaSwitch allows for 14
linecards to be installed into its back providing for a total of 32 simultaneous
network connections.
SPECTRUM supports the following firmware revisions:
2.00, 2.10, 2.20.
Support is currently available only for the FDDI GigaSwitch hub, but support
for the ATM hub will be available in a future release.

9031754 E5

SPECTRUM and the DEC GigaSwitch

SPECTRUM and the DEC GigaSwitch
The DEC GigaSwitch Management Module model will allow modeling of the
DEC GigaSwitch device.
Supported Devices: GigaSwitch/FDDI
Supported Cards: FGL2, SCP, Clock card
Firmware Versions: 2.00, 2.10, 2.20

NOTE

If you are running a previous version of SPECTRUM, the following user
interface aspects may differ from those in SPECTRUM version 4.0:
• Order and names of menu selections
• Navigational features (mouse button functionality)

DEC GigaSwitch Applications
The DEC GigaSwitch supports both common and device-specific applications.
SPECTRUM management of the DEC GigaSwitch utilizes the following
Management Information Bases (MIB’s) which come as a part of the software
module for the model type:
•
•
•
•
•

Internet MIB-II (RFC 1213)
IETF Bridge MIB (RFC 1286)
RFC 1285 (FDDI)
DEC Elan Vendor MIB (Version 2.7)
DEC GigaSwitch MIB (Version 1.0)

The MIB-II, IETF Bridge MIB, and the FDDI applications are described in the
Applications documentation.The DECGigaApp and the DECElanApp are the
GigaSwitch’s device-specific applications and are detailed in Chapter5, DECSpecific Applications.

DEC GigaSwitch
Management Module Guide

Chapter 2
Device View

What Is in This Chapter
This chapter describes the Gigaswitch’s Logical. Interface and Physical Device
views and how to utilize these views to manage and access information from
the Gigaswitch module. The Logical Device view provides a logical
representation of the Gigaswitch module and access to configuration and
status information on the module itself, the Ring In and Ring Out ports, and
the station ports.
The Interface Device view displays interface icons for each of the linecards
installed in theGigaSwitch, allowing you to set and gather information about
each of the interfaces.
The Physical Device view provides a physical representation of the Gigaswitch
and allows access to configuration and status information for the Gigaswitch
module.

Logical Device View
This section describes the information available from the Gigaswitch Logical
Device view.
The following diagram illustrates how to access the Gigaswitch’s Logical
Device view and Figure 2-1 shows the module’s Logical Device view. The
Logical Device v iew provides access to detailed information about the
Gigaswitch module. Figure 2-2 displays the Gigaswitch Logical Module and
the menu selections available by double-clicking the left mouse button on each
zone of the module.

Accessing the Logical Device View
The Logical Device view is accessed using one of the following methods:
• Double-click on the Device view button of the Gigaswitch device icon. This
will open the Device view that was opened last (i.e. Logical, Physical, or
Interface).

destination address is a multicast address.
The Flooding Table details the Qualifier, Class, Bytes Sent, Packets Sent,
Geezers, Losers, and Hogs information for each of the active cards on the
GigaSwitch.

GigaSwitch Cut Through Mapping
The GigaSwitch Cut Through Mapping table allows the user to enable or
disable the Inbound or Outbound Cut Through Mapping application for each
of the GigaSwitch Bridge Ports. The Cut Through Mapping feature allows
packets with known IP addresses to travel through the GigaSwitch with out
being temporarily stored within the GigaSwitch. Packets without known IP
addresses for their destination are temporarily delayed while the GigaSwitch
learns the IP address.
The default setting for each of the Bridge Ports is Enabled for both the
Inbound and Outbound Cut Through Mapping applications.

Configuring Cut Through Mapping
1. Double-click on the appropriate Bridge Port number to generate the Cut
Through Table View.
2. Click on the Inbound and Outbound buttons so that they display the
appropriate settings, either Enabled or Disabled.
