Purpose of the GIGAswitch System

Purpose of the GIGAswitch System
General
Description

The GIGAswitch System is a standalone, intelligent, switching
system that forwards packets among a set of connected data links.
The data links can be connected to end stations, bridges, routers,
and to other GIGAswitch Systems. The core of the GIGAswitch
System is a crossbar switch (CBS) card that forms point-to-point
communication paths by mapping inputs to outputs.
The GIGAswitch System acts as a multiport FDDI bridge with
all attached local area networks (LANs) being bridged together.
Subsequently, added line cards will have their data links
automatically added to the bridged LANS.

Versions

Two versions of the GIGAswitch System are available.
The DEFGA-BA version is compatible with the US power
requirements. The DEFGA-BB version in conjunction with a
selected country kit is compatible with the power requirements
for the selected country. See Appendix A for a listing of the power
cord types found in country kits.

Functions

Both versions (DEFGA-Bx) function as a modular, multiport,
FDDI bridge that uses the CBS card as the interconnection
mechanism for its line cards and processing engines. The
DEFGA-Bx utilizes both distributed and centralized packet
processing algorithms to perform the following ANSI and IEEE
802.1d bridging functions:
•

Forwarding

•

Filtering

•

Learning

•

Aging

•

Testing Procedures

Testing Procedures
Module self-tests (MSTs) are initiated when power is applied or
when the system is rebooted. See MST summary to interpret the
results of the MSTs.
The diagnostic mode can be used to run selected tests multiple
times to isolate intermittent faults. (See example on the next
page). When the fault is identified Repeat the MSTs to ensure
that all faults have been corrected.

Example
of Using
Diagnostic
Mode

The following figure is an example of using the diagnostic mode
to isolate an intermittent fault in the clock module. Complete
navigational information for the diagnostic mode is also provided.
For a list of available tests for a given module type "li" at the
Diagnostic Dispatcher prompt.

Description of
Example

After rebooting into diagnostic mode and entering the CLK
Diagnostic Dispatcher mode the following line was entered to
set the number of passes from 1 to 10 and to inhibit all outputs
except the summaries. Since the module will be replaced if any
test fails, it is not necessary to see the other displays.
After setting the default switches, test 101 was run 10 times. The
summary indicates the results of the test.
A line card or an SCP card can be tested using the same
commands once the Diagnostic Dispatcher mode for that card is
entered.

Logic Modules C–5

SCP Card

SCP Card
The switch control processor (SCP) card (DEFGP-AA) is a member
of the SCP card family of logic modules.

Application

The most common application for the SCP card is to serve as
the System Control Processor (SCP) for the GIGAswitch System.
During system initialization, an election takes place in software
to assign one SCP card the role of primary SCP. If other switch
engines are installed, they might be used by the system as backup
SCPs for redundancy.

SCP Function

The SCP function includes central functions such as initialization,
remote management, and control of services (such as bridging)
that are distributed across modules.
One of the major bridging services is to send and receive packets
that cannot be handled by the line cards. The SCP card sends
and receives packets for these purposes, among others:

C–6 Logic Modules

•

Exchanging intraswitch control packets between SCPs and
line cards, including background monitor (keep-alive packets,
address learning packets for transparent bridging, and packets
to read or set management parameters.

•

Forwarding multicast packets to an SCP by each line card.
The primary SCP uses special resources in the system to
broadcast each packet to the proper set of outbound line-card
ports and other switch engines.

•

Interpreting network control packets diverted from line cards.

•

Acting as a station on the network and emitting packets for
remote management the GIGAswitch System.

Clock Card

Clock Card
The clock card (54-22120-01) is a member of the clock card
family of logic modules. The clock card must be included in any
GIGAswitch System configuration.

Application

The clock card performs the following functions:
•

Clock generation and distribution

•

Arbitration

•

Terminal or modem interface

•

PSC card interface

•

PSC card power source

Clock
Generation and
Distribution

The clock card generates master system clocks and distributes
them through the backplane to each of the line card and the SCP
card. This allows resources associated with the backplane (in
particular the CBS card and the Backplane bus) to be used in a
synchronous and efficient manner.

Arbitration

The clock card also arbitrates access to the backplane bus to grant
ownership of the potential users in a fair manner.

Terminal
or Modem
Interface

The clock card provides the GIGAswitch System user with a
standard terminal or modem interface conforming to RS232
specifications, and compatible with RS423. The interface can
be used to connect a terminal to GIGAswitch System for local
management and diagnostic purposes. Full modem support is also
provided for remote maintenance and diagnostic support.
User specific parameters, such as baud rates, stop bits, parity,
data length and so forth are stored locally on the clock card in
nonvolatile (FLASH) memory.

PSC Card
Interface

Line Card
Monitoring and
Power Control

The clock card receives environmental status from the PSC card
when requested. This status includes:
•

Power supply status

•

The state of the fans

•

Ambient temperature

The clock card monitors line card, SCP card, and CBS card to
determine the type of card present during power initialization,
and to determine when a card is removed or inserted. The major
functions of the clock card are:
•

Clock generation and distribution.

•

Backplane bus arbitration and power sourcing.
Logic Modules C–9

Clock Card

•

Arbitration and tie breaking on behalf of the SCP card.

•

Local console (terminal or modem interface.

•

Sensing and control of the environment and of other modules.

In addition, many centralized resources exist on the clock card.
Examples of such resources include the many Ethernet addresses
associated with each GIGAswitch System platform, network and
local management parameters, and parameters learned about any
local topology.

Guidelines for Installing Additional Modules D–3

Recommended Location for Logic Modules

Recommended Location for Logic Modules
Although line cards or SCP cards can fit in any slot (except 7 or
8) 1 Digit al recommends the positions identified in the following
figure for these reasons:
•

High availability: Zone 1 and zone 2 2 are cooled by different
fans so the first SCP card is placed in slot 4 (zone 1) and the
second SCP card is placed in slot 13 (zone 2).

•

Minimum future upgrade impact: 2-port backplane slots 3
are filled first. This leaves the 4-port backplane slots 4 open
for 4-port line cards when they become available.

The following figure identifies where each additional line card and SCP card should be
installed §.

Slot 7 is reserved for the CLK card only. Slot 8 is reserved for the CBS card
only.
