Switching Technology

Demand for network bandwidth continues to grow, driven by the increasing number of systems us ed in net work-inte nsive applic ations . LAN segmen tatio n has been the prevalent method for addressing these demands and has been further popularized by tre nds toward server centralization. However, the implementation costs of LA N s eg mentation , as w el l as the real per fo r mance char ac te r ist i cs of conventional network components, have served to limit growth of some TokenRing networks. Alternative technologies for addressing bandwidth demands present yet other inhibitors, usually relating to costs. Token-Ring switching provides users with an easy, cost-effective technique for addressing these demands.

Token-Ring s wit ches, s uch a s th e C rossFi re 8600 and the CrossFi re 8 605, in cre ase throughput between Token-Ring segments by supporting simultaneous, parallel conversations. Switched connections between Token-Ring segments last only for the duration of the packet—new connections can be made betwe en different segments for the next packet.

Token-Ring switches solve congestion problems caused by high-bandwidth devices and powerful applications as well as the number of users. Therefore, each of these devic es—servers , for example —can be assi gned its own 16 Mbps seg ment.

In Token-Ring networks, the major bottlene ck is typically the throughput to highbandwidth devi ces suc h as servers , and be tween r oute rs, b ridg es, and s witc hes. An effective solution is full-duplex communication, an option for each segment connected to a CrossFire 8600 or a CrossFire 8605 port. Normally, Token-Ring operates in half-duplex communication mode , which means stations can either receive or transmit. With ful l-duplex technolog y, two communicating stations can transm i t an d re ce ive at the sa me ti m e . W h en pa ckets can flow in b ot h di re ct i on s simultaneously, effective Token-Ring bandwidth doubles from 16 Mbps to 32 Mbps.

The CrossFire 8600 and the CrossFire 8605 can forward Token-Ri ng frames among multiple, shared or dedicated Token-Ring LAN segments. Using a frame forwarding techn ique si milar to t hat of a mult iport Tok en-Ring t ranspa rent bri dge , the switch uses Token-Ring MAC addresses to forward Token-Ring frames from any of its ports to any other.

Switch of Switches

The CrossFire 8600 and the Cr ossFire 8 605 can be dep loyed in a variety of network configuration s, all o f whi ch provide a s i gnifica nt in cre ase in ne twor k perform ance . The series of Olicom Toke n-Ring products allows users to build network systems that can transport data efficiently and scale upwards as throughput requirements increas e. The s witche s del iver hig h-rel iabil ity an d media flex ibilit y. The se featu res combine to allow the switches to be used as a switch of switches which provides media flexibility in an Token-Ring configuration.

The CrossFire 8600 and t he Cross Fire 8605 can e asily conne ct with other CrossFire products to de liver a broa d range of networ k carrying capacit y. Bandwidth is easily scaled to meet all performance requirements.

Switch of Servers

With client/server applications, many client workstations may attempt to access a single server at the same time. This traffic pattern may create bottlenecks at the server. To further enha nce performance, the CrossFire 8600 and the CrossFire 8605 can deliver dedic ated bandwidth to high-spe ed file servers. All servers perform better with ded ica ted 16 Mbps bandwidth.

Even better performance can be achieved by installing multiple adapters in the server. By connecting these adapters to the switch, multiple 16 Mbps paths to the server ar e created, a solution that is on ly possible when using a switch.

The switch ties together all Token- Ring devices lined to a loc al wiring center. In networks, wher e a significant portion of the traffic moves locally between client and server, the switch can be very effective.

Switch of Hubs

When network traffic increases beyond the capability of hubs, contention results. Applications suffer and may even fail. The net effect of such a network configuration is that all devices share a single 16 Mbps data path, thus reducing overall network efficiency. The CrossFire 8600 and CrossFire 8605 can be very effective when used as a switch of hubs.

The switches ca n alleviate contention through microsegmentation , or reducing the number o f devices i n each shared segment. To p r o v ide micro segmentat io n, the switches divid es a sing le 16 Mbps segmen t i nto mult ipl e 16 Mbps se gment s. As a n example, a workgroup has 16 Mbps of capacity. The 20 ports on the switches support 10 s imultaneo us conver sations wit h 20 hubs, t hus pro viding the workgroup with 160 Mbps bandwidt h throughput, which results in a s ignificant gain in bandwidth .

Switch of Desktops

The CrossFire 8600 and the CrossFir e 8605 are a c ost-effecti ve means of pr oviding dedicate d bandwidth to individual desktop workstations. In this applicat ion, the switch replaces a hub, providing excellent, hub-like network management statisti cs. Total network ca pacity and t hroughput increase dr amaticall y for atta ched desktop workstations.

Switch of Floors and Buildings

For network mana gers , multis t orey bui ldings and c ampuses c an represe nt a unique networking chal lenge. How can a network manager provide an ef ficient LAN interconnec t for users that ar e lo cated on s everal floors of a buildi ng or in differen t buildings?

Token-Ring switching and the CrossFire product family can provide the best solution. T he CrossFire 8600 and the CrossFi re 8605 pr ovide enhanc ed throughput to local wiring closets that can be connected to a switch located in the data center.

Many networks consist of users located in different buildings of a campus environment. The switches can be used as a collapsed backbone interconnecting multiple buildings of a campus. They can provide the connectivity solution and enhanced throughput that such campus environments require.

Switch of Routers

Router technology has had a significant impact on the design of today’s internetworks. Rout ers ha ve be come the cor nerst one of m ost pro ductio n networks . Although well equipped to provide firewall, WAN connectivity, security, and connection betwe en dissimilar LANs, routers are unable to provide hi gh throughput between desktop de vices and servers. Because of these limitations, routers and switches perform complimentary functions in the network.

The Cross Fire 8600 and t he CrossFire 8605 can be used as a front-en d to routers to increase performance in each subnet. Communication between local clients and servers is enhanced at the workgroup level below the router.

The switches can also be used to back-end routers. In networks were many route rs are intercon nected over Token-Ring and backbone performance is not acceptable, the switches provide non-blocking communication between the rout ers for enhanced network performance. This provides prot ocol transparency with enhanced throughput in each subnet between local servers and desktops, thus allowing network managers to build logical networks as large as network layer protocol and broadcast traffic allow.

The SwitchProbe (Switched Port Analyzer) also gives a collapsed backbone network superior net work management and the abilit y to perform protoc ol analysis from a singl e loc ation . The SwitchPr obe (Swi tc h Port Ana ly zer) p rovi des the l atest technology for monitoring switch-based networks and helps to reduce the cost of man ag ing the s e networks.

2. Switch Theory of Operation

This chapter explains how the CrossFire 8600 Toke n-Ring Switch and/or the CrossFire 8605 Token-Ring Fiber Switch improve network performance.

The topics of this chapter are presented under the following titles:

•

“How the Cros sFire 8600 and t he C rossFi re 8605 Works”, starti ng on page 17.

•

“Benefits of the CrossFire 8600 and the Cr ossFire 8605”, starting on page 32.

How the CrossFire 8600 and the CrossFire 8605 Works

The CrossFire 8600 and the CrossF ire 8605 are both IEEE 802.5 -compliant devices designed to boost throughput on Token-Ring net works. They operate as a Media Access Control (MAC)-layer device that is protocol independent.

This chapter describes how the switch operates as a single stand-alone unit. The switch contains the followin g main element s, as listed below:

•

Switching Bus—t he arch ite cture of the s wit ch c enters ar ound the AXIS b us, a 520 Mbps switching fabric through which all switched ports communicate. The AXIS bus is a partially asynchronous time division multiplexed bus used for switching packets between heterogeneous LAN modules.

•

Token-Ring Ports—each port can attach to a classical Token-Ring segment or to a dedicated sta tion. Now users running bas ic application s a r e able to share bandwidth, and users running bandwidth-intens ive applications can receive their own dedic ated 16 Mbps port. Each dedicated port can also be set up in full-duplex communication mode, so that each 16 Mbps port doubles to 32 Mbps.

•

Expansion Modules—each switch supports two expansion modules. These modules include RJ- 45 or fiber port s to provid e up to eight ad ditional 16 Mbps ports, or high -speed conne ctions suc h as 155 Mb ps ATM, to provide tw o ATMRing connections for s ervers or backbone connectivity.

•

Stack Link Module—the switch su pports a stack lin k module t hat can be us ed to connect two switches from the CrossFire 8600 series in a back-to-back configuration. Alternatively, up to five switches can be connected together using and internal s tacker module, and up to eight switches can be connected together using the stack link module and an additional switch stack unit. By connecting switches together through the stack link module, the switches virtually c o mbine to form a single unit, providing scalability, simplified management, and enhanced performance.

Multiple Simultaneous Conversations

A limitation of Token-Ring is that it supports only one packet at a time . The CrossFire 8600 and the CrossFire 8605 improve data th roughput by supporting multiple, simultaneous, full-duplex conversations. By using High-Speed bus switching technology, the switch creates multiple data paths. These switched connections between Token-Ring segments last only for the duration of a byte transmission. New connections are made “on-the-fly” between different ports on the switch for the next byte.

Figure 5. Multiple Conversations Thr ough a CrossFire 8600 or

CrossFire 8605 Swit ch

For example, as shown in Figure 5, while host A is transmitti ng a byte to host B, the swi tch connects o nly the lines from A to B si nce th ere is no ne ed to send packet s to all other ports. At the same time, a second switching circuit can connect host C to host D. The result: Two packets are sent simultaneously.

simultan eous ly.

The increase in thr oughput is directl y proportional to the number of physical toke nrings that are interconnected through the switch. A switch with 20 ports interconnec ted provides up to ten concurrent paths. With ten simultaneous

Page 35

conversation s, the switch creates 1 60 Mbps th roughput in half-dup lex mode, or 320 Mbps throughput in full-duplex mode.

A single segment can be dedi cated t o a si ngle host or share d by sev eral. To optimize throughput, high-speed servers can be given dedicated switch ports.

By transporting multiple Token-Ring packets simultaneously, it boosts overall network throu ghput.

Low Latency

When operating in cut-through mode, the switch mi nimizes latency—the tim e it takes to forwa rd a pack et from one T oken-Ri ng seg ment to another —by begi nning switching i mmediatel y af ter look ing a t the fi rst six byt es of t he des tinat ion addre ss in the pack et. If the packet needs to be swit ched to another LAN segment, its da ta begins flowin g through the destination port before the entire packet has been received. The res ult: packets can appear at the output port 35 microseconds after entering the input port. Network devices that us e store-and-forward tech nology introduce m uch longe r delay s becaus e they wait to re ceive the ent ire packet bef ore forwarding it .

By minimizing delay, the switch can move more packets freely throughout the LAN without degradi ng performance.

Address Management

At power up, the system address t ables do not contain any information. Wheneve r a switch receives a packet wi th a n unknown s ource or de sti nation a ddres s, it le arn s the new source address and stores its location in coming port in the address table. If the dest ination a ddress i s unknown it sen ds the packe t to al l ports that can r eceive data from the incoming port. When the res ponse packe t comes back, the s witch will learn the responder’s location and adds it to the addre ss table. Once the address table entries are created, th e switch uses these learn ed address to switch all subsequent packets to the port where the destination address is located.

The system addres s table maintains up to 10, 000 entries, and each po rt address table maintain s 5,500 acti ve Token -Rin g addres ses (ea ch port addre ss tabl e is sha red by four ports, using the followi ng: 1- 4, 5- 8, 9-12, 1 3-, etc. ) . If an ad dress ha s not been active for a configurable aging tim e, it is re moved from the tables. Thi s ensures that the port’s address table is populated onl y by the most recently used address .

This capability allows users to transparently connect to high-volume backbone networks.

Multiple Bridging Modes

The CrossFire 8600 and the C ross Fire 86 05 each supports four dif f erent swit chi ng modes to provide maximum flexibility in all installation e nvironments. The switching modes are Source Route Switching (SRS), Source Route Bridging (SRB), Source Rout e Transparent (SRT) and SRT/SRB. The switch operates on two levels (BRF and CRF) as outlined below.

Figure 6. Typical Configuration with Switches Using Multi ple Bridging Modes

The switch bridging modes are founded on the concept of Logical Rings. This Logical Ring concept is equivalent to the DTR (IEEE 802. 5r) standard’s Concentrator Relay Function (CRF).

Each port on the switch belongs to a Logical Ring (CRF ), which is a logical grouping of ports within the switch. A Logical Ring can consist of any number of ports within a swit ch or a switch stack. The ports withi n a Logical Ring do not have to be adja cent.

The Logical Rings are assi gned a ring number when the switch performs source routing functions. The bridging is performed through the logical entity of the Bridge Relay Function (BRF).

The Logical Ring (LR) communicates via a logical, virtual port with the Bridge Relay Funct ion, which functions as a multi port (virtual) bridge between the Logical Rings. The switch can support up to 63 logical rings.

CrossFire 8600/8605 Token-Ring Switches v. 1.2, P/N: 710001641 Switch Theory of Operation

Page 37

There are two levels of relay functions supported by the switch. The first level is the TrCRF (Token Ring Concentrator Relay Function) to which the ports are assigned. The secon d level i s th e TrBRF (To ken Ring Bri dge Rela y Functi on). This is the parent r elay function to which TrCRF s ar e assigned. The switch mai ntains certain configuration information and management statistics on a per BRF/CRF basis. Therefore, when you access VLAN-specific switch configuration or management screens (such as the you will be prompted to specify the desired TrBRF for TrC RF.

Source Route Bridging (SRB)

The BRF acts as a multi port Source Route Bridge betwe en CRFs with the following characteristics:

•

Each Logical Ring has a different ring number

•

Source Route Frames are forw arded between the Logical Rings by the Br idge Relay Function based on the route information f ield

•

Non-source-route f r ames are not forwarded between logical rings

•

The Bridge Relay Function has a single bridge number and mult iple ring numbers (one per Logical Ring)

SRS is used betwee n the ports of each logical ring. The Bridge Relay Functi on runs the IBM Spanning T ree Protocol t o eliminate parallel paths with othe r source-route bridges. T he IEEE 802.1D Spanning Tree Protoc ol is still used with each logical ring. Duplicate MAC addresses are allowed Rings.

Source Route Tra nsp aren t (SRT)

The BRF can combine transparent switc hing with Source Route Bridging. Non source-rout ed packets are switched across logical rings by transpa rent bridging.

The purpose of the SRT/SRB mode i s to allo w duplicate MAC address es to be use d when in SRT mode. The port s on which the dupli cate MAC addr esses reside c an be reached only by source routing.

The Bridge Relay Fu nction runs the IBM Spanning Tree Protocol on the SRB logical rings to eliminate paralle l paths with all source route bridges. It runs IEEE

802.1D Spannin g Tree Prot ocol on the SRT logica l rings to elim inate pa rallel paths with other SRT bridges. The two resulting spanning trees are joined together.

The IEEE 802.1D Spanning Tree Protocol is still used to eliminate parallel pat hs within each logical ring whether it is SRB or SRT.

The benefit of the SRT/SRB mode is that it all ows part of the network to be run in SRT mode to accommoda te application s that do not support source routing, while still supporting dupli ca te MAC addresses on a number of S RB ports (for example, for SNA gateway applications).

Filtering

Filtering is important for a LAN switch. Filters can be used to reduce broadcast traffic, bloc k ce rtain protocols and provide security functions.

The switch provides filters for:

•

Destination or s ource MAC addresses

•

Destination service access point (DSAP)

•

Subnetwork Access Protocol (SNAP) type

Each protocol filter can be applied on a per-port basis for both input and output traffic. This feat ure al lows certain protocols to be blocked from certain ports. For example, filters can be established to allow only Systems Network Architecture (SNA) traffic to f low to ports with SNA gateways.

Source and destinat ion MAC address filtering can be applied to all incoming frames. The MAC address filters act in one of three ways:

Page 39

•

Block destination address at a specific port—this prevents the spe cified port from sending frames to a specified destination.

•

Allow destination addres s at specific ports—this indicates that the specified port must send frames to the specified destinations

•

Force destination address to a specific port—this allo ws forwarding to a unicast address that has not been learned. It can also be used to limit the forwarding of Multi cast addresses to a subset of ports. This last filter applies to non-source-routing frames

only

Congestion Control

At regular intervals, the switch CPU inspect s the queues on all output ports. If a queue size is above a cer tain threshold, the port is ins tructed to:

•

Set the transmit priority f or low priority frames to a spec ified high level

•

Delete old frames from the queue until it reaches a specified size

When the queue size agai n com es below a normal threshold size the port is instructed to set the transmit priority back to the normal level.

Three Switching Modes

Cut-Through

In this mode the switch starts forwarding the packet to the output port as soon as the destination address or the source-route of the incoming packet has been resolved. Th is te chniqu e e nsures ve ry low la tency , t ypical ly in t he range of 30 -100 µs. However, if errors occur on the input port during the reception of a packet, the error will still be forwarded to the output port . Note that cut-through can only be used in transmis sions between ports which oper ate at 16 Mbps.

Store and Forward

In this mode, the switch receives the total packet from t he input port, checks it for any errors and then st arts forwarding the packet to the destination port. This technique wil l ensure that no faulty packet s ar e transmitted by output port. The negative impact however, is higher latency, typically in the range of 40–2,000 µs depending on the packet size. Though slower than cut-through mode, this is still much faster tha t conventional bridges.

Auto (Adaptive C u t-T hrough)

This is a te chnique whereby t he swit ch will automati ca lly swa p betwe en stor e-andforward and cut-through modes based on an error threshold. If the number of received faulty packets is low, then cut -through mode is used; if the number of

Page 40

faulty pack ets is hi gh, t he store a nd fo rward mode is use d. Th is pro vide s opt imiz ed performance but introduces variable late ncy.

Token-Ring Port Operation Modes

Each Token-Ring port may operate in one of the following modes:

•

Half-duplex concentr ator port

The port be haves like an active MAU port for classical Token-Ring. Connects to a single station in half-duplex mode. This is also known as Token Passing (TKP) port mode.

•

Half-duplex station emulation

The port is conne ct ed to a por t on a MA U. Con nects to a class ical Token-Ring segment with multiple stations. This is also known as Token Passing (TKP) station mode.

•

Full-du plex concentrator port

Connects to a single station or to another switch in full-duple x mode. This is also known as Transmit Immediate (TXI) port mode.

•

Full-duplex station emulation

Connects to another Token-Ring switch. This is also known as Transmit Immediate (TXI) station mode.

•

RI/RO-like connection

The mode of operation can be configured manually or sensed auto ma tically with the exception of RI/R O, when equipment i s connected to the port. The media spe ed (4 or 16 Mbps) can also be manuall y configu red o r automa tica lly sens ed in al l por t modes.

RI/RO-Like Connection

On CrossFire 8600, a RI/RO-like connection is available on fiber expansi on ports and on ports 19 and 20. On CrossFir e 8605 , a R I/RO-l ike c onnect ion is p ossi ble on all the 20 fiber ports and on fiber expansion ports.

This feature allows the switch to connect to CAU/LAM systems us ing the RI/RO connections thus providing a RI/RO-like functionality. This enables the switch to be eas ily insta lled in ex isting To k en-Ring netw or k s .

A loop-back function has been implemented on these ports so that if the port is disabled or the swit ch is powe red off there will not be a break in the atta ched main ring. This means that attaching a cable from the RI port of a MAU port to one of the two switch port s in effe ct joins the primary and the backup r ing in a MAU/CAU main ring system. Connecting the other end of the RI/RO conne ction to the other switch port,

Transmission Priority Queues

To address the needs of delay-sensit ive data, such as multime dia, the Token-Ring ports of the switch have two transmit queues, a high-priority queue and a lowpriority queue.

The queue for a frame is determined by the value of the priority field in the frame control (FC) byte. If FC priority is above a configura ble level (default 3), the frame is put into the hi gh-priority queue. If an output port becomes congested, you can dynamically configure the port to transmit all frames at high priority regardless of the FC byte contents.

CrossLink Connections

Two switch stacks or switches may be interconnect ed by a number of parallel Token-Ring con nec tions (up to 256 Mbps using eight por ts ). The traffic between the switches will be shared between the connections.

Spanning Tree Protocol Support

IBM initi ally supported only Source Route Bridging (SRB) in its bridges, so most networks were built to use it . T he main consideration for SRB implemen tations in switches is the spa nning-tree algorithm for spanning tree explorers (STEs). IBM originally implement ed a form of the Institute of Electrical and Electronics Engineers (IEEE) spanning-tree algorithm. This algorithm, commonly referred to as the IBM spanning tree, limits the STE frames to one copy per destination ring. Some SRB implementations have also implemented the IEEE Spanning Tree Protocol to be compatible with SRT br idges. The IEE E Spanning Tree Protocol is not compati ble with the IBM Spanning Tree Protocol.

The switch suppo rts both the IEEE 802.1D and IBM Spanning Tree Protocols.

VLAN Support

The vir tu al LAN (VLA N) c onc ep t c rea te s a vir t ual sw it ch wi thi n a ph y sica l s wi tch or stack of switche s. A VLAN consists of CRFs and has its own Bridge Relay Function atta ched. Frames are not forwarded across VLANs and ring numbers must be unique within a VLAN.

•

A VLAN consists of a number of ports of a switch or stack of switches

•

No frames are forwarded betwee n ports belonging to dif ferent VLANs

•

Logical ring s on dif fer ent VLANs may be assig ned t he same ring num ber , b ut ring numbers must be uni que within the same VLAN

•

For each VLAN, the stack can be assigned a separate IP address

•

The spanning tree pr otocol is execut ed independently within ea ch VLAN. However, since al l B RFs use the same Bridge ID for th e s p an n i ng tr e e algorithm, the spanning tree protocol will not function if ports from different BRFs within one swi tch are connected.

A sample VLAN with a CrossFire 8600 or a Cross F ire 8605 is shown below.

Some error reporting functions and ring map functions might be lost for the rings attached t o through the switc h, because a Token-Ring Switch will not (and should not) forward MAC frames, but only LLC frame s between ports.

RMON Support

RMON is an i ndustry -sta ndard m ethod for p rovid ing network stat isti cs monito ring using SNMP. It al so col lect s faul t, pe rformance, and c onfi guratio n sta tist ics. It ca n monitor continuously, even when communi cation with the management station is not po ssible or e f f ic ient. RM ON can th en notif y the man ag ement s tation w h en an exceptiona l condition occurs.

In typical SN MP manageme nt, the SNMP client has to continuous ly poll th e swi tch for fault, performance, and c onfiguration information, waiting for the value to change. This causes increased traffic thr ough the network. With RMON, you can have the switch monitor a part icular statistic internally, and when the statistics reaches a threshold, the switch will send a trap to the client. T h is monitoring method reduces traffic between the SNMP client and the s witch.

The following groups defined in the RFC 1757 RMON MIB are supported in the switch:

Stackable Architecture

The CrossFire 8600 and the CrossFire 8605 switch can be stacked using the CrossFire 863 0 Stacker Link module, the CrossFire 8635 Internal Stacker mo dule or the CrossFir e 8300 Switch Stacker for conne cting up to eight switc hes in a stack.

Back-to-Back

Two CrossFire 8600 series switches can be connected together by fitting each switch with the CrossFire 8630 Stacker Link module and connecting the switches together using an appropriate stacker link cable. This simple connection doubles the number of ports available, giving a total maximum of 56 ports.

Internal Stacker

The CrossFire 8635 Internal Stacker Module can be inserted into the stacker port of a switch. It allows up to four additional switches from the CrossFire 8600 series to be stacked together with the switch containing the CrossFire 8635. Each switch in the stack must be equipped with a CrossFire 8630 Stacker Link module and an appropriate stacker link cable. This can result in a stack of as many as five CrossFire 8600 series switches, supplying a total of up to 140 switched Token-Ring ports. The CrossFire 8635 Internal Stacker Module works as a common backplane switching fabr ic, which provides 1. 4 Gbps of aggregate bandwidt h.

External Stacker

The CrossFir e 8300 Swit ch Stack er is an exte rnal s tack uni t that a llo ws up to eig ht CrossFire 8600 series switches to be stacked together. Each switch in the stack must be equipped wi th a n CrossF ire 8 63 0 Stacker L ink Mod ule and an a ppropria te stacker link cable. Thi s can resu lt in a to tal of up to 224 swi tched Token-R ing ports. The CrossFire 8300 Switch Stacker works as a common backplane switching fabric, which provides 2.2 Gbps of aggregate bandwidth.

➽ Note:

The CrossFire 8600 and the CrossFire 8605 can be stacked together with switc h es f r om th e Cr o s sFire 8600 ser i es in any desired co m b in a ti o n. All switc h es in a stack m u st , however, run th e same softwar e ver sio n .

Optional Redundant Power Supply

The switch has an input for a backup power supply.

Rules to Remember

This section wil l help you unde rstand the physical con figurat ion restrict ions for the switch. In brief, you must remember the following rules when planning to install the swi tc h :

•

18,192 byte maximu m phy sical frame length.

•

For s h ared-med ia LAN se g ments, acceptable distances are defined by the hu b or concentrator attached to the switch port.

•

Straight-through cables for all ports.

•

If you create parallel pat hs direc tly between switches, be sure that you have enabled the spanning tree protcol (see “Spanning Tree for TrBRF Screen” on page 99). The default setting for the spanning tree pro tocol is disabled.

•

The spanning tree protocol will not function between different BRFs within one switch.

The following paragraphs provide greater detail about the physical restrictions.

Frame Length Li mit

The switch suppo rts a maximum physical frame length of 18, 192 bytes. This corresponds to a Maximum Transfer Unit (MTU) of 17,800 byte s. The default maximum physical fra me len gth of the switc h is 4,546 bytes which corr espond s to an MTU of 4,472 bytes.

Please read sect ion “Required Network Preparation - F ram e Length Limit” on page 55 before you start the installation. This section contains more detailed information on the frame length limits.

Figure 9. A Simple Application of the Switch

Some large, mult is egment, hierarchical Token-Ring networks experience congestion at the campus backbone level. Although this congestion can oft en be relieved by converting the backbon e to a higher s peed, share d-media protoc ol or by install ing additional bridges or dual backbones to eliminate bottlenecks , the CrossFire 8600 switch an d/or the CrossFire 860 5 switch o ffer dedicate d-media that might be longer lived or more economical if you eventually need higher demand applications.

Figure 10 o n the ne xt pag e i llus trate s a typic a l network wit hout the Cro ssFi re 8600 or the CrossFire 8605 switch. This network is a three-level, hierarchical, campu s network. Figure 11 and Figure 12 offer several alternatives for using the CrossFir e 8600 or the CrossFire 8605 switch.

The Next Step

Typically, the first point of congestion in this newly configured network would be the server s. Because the usual m ode of operation for a To ken-Ring adapter is halfduplex, the servers can either send or receive information with one other segment attached t o the swit ch. I f t he server adapt ers are re plac ed wit h f ull-dupl ex adapt ers, such as the Olicom OC-3118 or the Olicom OC-3137, and are attached as singlestation segments as shown in Figure 11, they can send and receive data simultaneo usly. The capacity of each server is now 32 Mbps per port.

However, network congestion is not always at the ba ckbone level. In Figure 12, the two MAUs and six bridges have been replaced by a single switch. Internally, the switch is c onfi gured wi th one BRF a nd se ven CRFs , allowi ng t he s witch t o re place the MAUs and bridges without the need for further reconfigurat ion. This configuration greatly improves performance by allowing switching directly from ring to ring. The four serve rs, each with a full-duplex con nection to the switch, have been grouped in CRF 5.

If even better perf ormance is needed, the switch s hown in Figure 12 can be replaced with a stack of s witche s. A stack c an pro vide up to 22 4 port s, maki ng it fea sable to connect workstations directly to a switc h port. A direct connection prov ides a dedicated 32 Mbps for users with high bandwidth requirements.

Important Management Considerations

A star-wired topology (see Figure 13) helps determi ne problems in a network because no single cable carries all of the traffic on the network. However, serial connections could reduce network reliability since each connect ing cable and switch could potentially divide the net work should a failure occur.

If you create parallel paths directly betwee n switches, be sure you have enabled spanning tree protocol (the default setting for spanning tree protocol is no or disabled). Parallel paths cr eate endless loops that cause unsatisfactory network operation unless you configure the switch for spanning tree capability. The spanning tree algorithm disconnects loops in networks using the transparent bridging algorithm or the SRT algorithm, and will block a port of one of the switches in the parallel paths . If the port in the primary path fails, the port that has been blocked will change automatically to the forwarding stat e, keeping the network operational.

4. Installation

This chapter contains step-by-step instructions for installing, connecting and verifying that the CrossFire 8600 Token-Ring Switch and/or CrossFire 8605 Token-Ring Fiber Switch is operating properly.

Required Network Preparation - Frame Le ngth Limit

The CrossFire 8600 and the CrossFire 8605 both support a

frame length

Sequence ( FCS) characte rs). This correspond s to a Maximum Transfer Uni t (MTU) of 17, 8 00 bytes.

of 18,192 bytes (from the Frame Control (FC) to the Frame Check

maximum physical

The

default

corresponds to an MTU of 4,472 bytes. The configured in the page 92.

The switch truncat es frames larger than the configured maximum p h y sical frame length and adds an abort sequence at the end. Characteristically, if frames are sent longer than the frame le ngth limit, the abort sequence s wil l be reported as frame errors by other ring stations.

In a stack of switches, all stacker link modules in the stack must support 18,192 byte frames (18 KB frames) for any switch in the stack to support frames sizes longer than 4,546 bytes. Additionally, if you are using ATM uplinks, all ATM uplinks in the switch and i n the st ack must suppo rt 18 KB fra mes for any swit ch in the stack to support frames sizes longer than 4,546 bytes.

To verify that your hardwa re supports 18 KB frames, view the

4. At power on (cold boot), the switch performs a series of self-test diagnos tics verifying t hat hardware component s are functioning. An example of the self-t est diagnos tic screen is s h own later in t his chapter.

Communication Problems

If the diagnost ic list does not appear, or is garbled, try adjusting th e baud rates between the console and the switch by using the Autobaud routine within the switch. To do this, press the reset button on the front of the switch and wait for the internal diagnostics to finish (the DIAG LED turns off). The reason for the reset is that in case the switch’s Autobaud routine is not enabled, resetting it will set it to its default mod e of Autobaud enabled.

Depending on the ty pe of console, there are seve ral console command keys that will potentially initiate the Autoba ud routine in the switch. Four of those keys are

RETURN

, the combination keys of

ALT-B

, the

BREAK

key, and

ESC

After the DIAG LED goes out, try one these command key s at the console, and press it repeatedly. If there is no response, wait several seconds and again, press it repeatedl y. If necessary, perform the same routine using the other command keys.

If that does no t work, and there is at l east a ga rbled output on the s creen, try pushing the unlabelled system request button on the switch. As soon as garbled characters appear, press the co nsole’s

RETURN

key twice in rapid suc cession. (Again, try the

other command keys as necessary). If there is still a problem, try the following steps:

1. Check all of the cable connections.

2. Check the baud rate at the console’ s set up screen; if it i s not set to 9600, try that setting.

3. Try setting the console baud rate to different val ues up or down, and pressing

RETURN

for each selection.

4. If you are using a terminal emul ation program, try exiting the program and restarting.

5. If you still can not get the connection to work, cont act technical supp ort as described in

Chapter 11, “Getting in Touch with Technical Support”

Diagnostic Screen

The diagnostic self-test displays two different screens (lists of informati on), depending on whether you perform a cold boot (power on cycle with full diagnostics), or a warm boot (a reset without full diagnostics).

Switch

This MAC address is used for the Token-Ring MAC protoc ol, and for the spanni ng tree protocol.

The switch reserves 63 addresses for TrBRF ( VLAN).

Each VLAN has an attached B r idge relay function (TrBRF) and a Management entity (IP -protocol st ack), an d consequent ly it needs a MAC Address. I n the swi tch, these two logical units use the same address, ho wever this address must be unique in the network. This is ensured by assigning MAC address to TrBRF’s from the Switch Base Address + 32 (0x20) and upwards. The switch is design ed in such a way, that it operates with 63 ac tive or preferred VLAN’s, implying that 63 MAC addresses need to be reserved for TrBRF.

Summarizing each CrossFire 8600 reserve: Swit ch Ba se Address + 31 Addresses for Token-Ring ports + 63 MAC Addre sses f or TrBRFs = 95, whic h is rounded up to 96 or hexadecimal 0x60.

The MAC address of the default TrBRF (trnet-default) will always be the switch base address + 32. If the swi tch operates in a stack, only one of th e switches will operate the brid ge re lay function. Hence the MAC address of the default TrBRF will be the base addr ess of the sta ckmast er + 32. The stackm aste r is determin ed by software, when the sta ck consists of two switches back to back and by the port

numbers in 8300/8635 stack configuratio ns. There is no s imple rul e t o f ind the MAC addre ss of othe r Tr BRF, but it i s always in

the range below:

Stack Master Base Address + 32 < TrBRF M AC Address < Stack Master Base Address + 95. And a TrBRF (VLAN) MAC address is assigned, when the VLAN b ecomes pref er r e d ( i. e. it has an as si g ned port in the ac tu al switch o r stac k o f switches) b y select in g the lowes t available MAC address above Stack Master Base Address + 32.

If management (SNMP or TELNET) contact with the switch is lost (e.g. because ports are moved from one TrB RF to another) it is suggested, that a terminal is connected to the OBM port of the switch stack, and the IP Configuration menu is entered. From here , it is possible to re ad the MAC address of the managem ent entity (TrBRF).

Address Format

Display format used for MAC addresses (canonical or non-canonical). Canonical format is typic ally us ed in Et hernet networks and is also kno wn a s least signi f icant bit fi rst. Non-canon ical is typi cally us ed in Token-Ring networks and is also kno wn as mo s t si gnific ant bit first.
