`Overview of the GIGAswitch/FDDI System
`
`General
`Description
`
`The GIGAswitch/FDDI System is a standalone data switch
`that implements the IEEE 802.1d bridge architecture. Packets
`are sent through a switching fabric consisting of a crossbar
`switch (CBS) which is capable of maintaining as many as 36
`simultaneous connections between inputs and outputs. Up to 34
`of the crossbar ports may be connected to external data links at
`any given time.
`Connecting crossbar ports to data links is accomplished by
`linecards, each of which may provide up to four (4) such
`connections. The GIGAswitch/FDDI System currently supports
`three types of linecards:
`• FGL–2 — 2 FDDI links
`• FGL–4 — 4 FDDI links
`• AGL–2 — 2 ATM links
`Each data link is in turn attached to either an FDDI ring, a
`single FDDI endstation, a single ATM endstation, an ATM switch,
`an FDDI bridge, or another GIGAswitch/FDDI System.

`
`As a multi-port bridge the GIGAswitch/FDDI System performs
`the following functions:
`• Forwarding — A packet entering the switch is forwarded to
`the appropriate output port (or ports), as determined by its
`destination address (DA).
`• Learning — Source addresses (SA) are automatically learned
`so that the switch can send packets to the proper output ports.
`• Filtering — Dynamic filtering assures that packets with
`destinations learned on a particular port are not forwarded to
`other ports.
`• Aging — Learned addresses are automatically aged out so
`that packets are not lost when network nodes move.
`• Spanning Tree — The GIGAswitch/FDDI System participates
`in the IEEE 802.1d Spanning Tree algorithm.
`
`The GIGAswitch/FDDI System supports several features that
`enhance performance:
`• Cut-through Forwarding — Packets are forwarded into
`the crossbar and onto the output data link as soon as the
`destination address is known, thus reducing store-and-forward
`delays. Cut-through forwarding may be optionally disabled.
`• Full-Duplex Operation — Point-to-point links can operate
`in full-duplex mode. Full-duplex operation may be optionally
`disabled.
`
`There are two management interfaces to the GIGAswitch/FDDI
`System:
`• Out of Band — A terminal connected to an RS232 port on
`the GIGAswitch/FDDI System provides limited management
`functions, used primarily for setting initial operating
`parameters and system security.
`• SNMP Management — The switch may be managed from
`anywhere in the network with any SNMP-based network
`management station (NMS).

`
`GIGAswitch/FDDI System Features
`
`Several special management features enable effective use of the
`GIGAswitch/FDDI System. Some of these are:
`• Management-defined Filters — Management filters enable
`the flow of certain traffic through the switch to be specifically
`restricted. Filters can be conditioned on inbound port,
`outbound port, SA, DA, protocol type, or some combination of
`these. Filtering does not impose any performance penalty.
`• Rate Limiting — Rate limits exist for flooded traffic. Rates
`can be independently set for multicast and unknown DA
`traffic. Rate limits prevent flooded traffic from monopolizing
`LAN bandwidth or switch resources.
`• Security — Various security mechanisms enable a system
`manager to maintain the integrity of the system operation.
`The OBM facility supports an optional password. SNMP
`employs passwords known as "community strings." A security
`keyswitch provides physical security over management access
`to the GIGAswitch/FDDI System.
`
`Other special features of the GIGAswitch/FDDI System
`architecture are:
`• Multiple Traffic Queues — As packets arrive they are placed
`on one of several queues, which are serviced independently, to
`assure the fair and timely processing of packets. This assures,
`for example, that spanning tree messages will not be delayed
`behind a long queue of data packets.
`• Service Classes — Protocols are assigned different service
`classes so that packet processing does not violate the
`assumptions of the upper layer protocols. For instance
`protocols which require in-order data link layer delivery are in
`one service class to assure this assumption is met.
`• Data Link Independence — A modular design assures that
`the switch operates in a way that does not depend on the
`physical link type—assuring present and future compatibility
`with any user environment.

`
`GIGAswitch/FDDI System Modules
`
`The following modules may be removed or inserted without
`affecting operation of the GIGAswitch/FDDI System (except, of
`course, the module being swapped):
`Linecards
`Switch control processor (backup)
`Fan tray assembly (redundant)
`Power interface unit (redundant)

`The expected behavior when these modules are inserted into or
`removed from a running GIGAswitch/FDDI System is described in
`the following two tables.
`
`Table 1–2 Behavior when Inserted

`Behavior when Inserted
`Linecard
`Module goes through normal self-test; then the forwarding
`database is loaded onto the module, and its ports enter the
`preforwarding state. If this results in a topology change, then
`other ports may also go into preforwarding as the spanning tree
`is recalculated.
`The inserted SCP becomes the backup SCP. There will be no
`observable effect on the operation of the GIGAswitch/FDDI
`System.

`Packets en route to or from ports on the removed card may be
`lost.
`If the backup SCP is removed no interruption will be observed. If
`the elected SCP is removed the GIGAswitch/FDDI System stops
`unless a backup SCP is present. In that case, the backup SCP
`becomes elected, and power cycles all linecards, resulting in an
`operational interruption while the linecards perform self-test, and
`the spanning tree is recalculated.
`No interruption in service if there is a redundant power supply
`present.
`No interruption in se
