The Cisco MGX 8850 (PXM1) node in Figure 1-2 is called a fee de r no d e. I n th e m u lti ser v ice edge aggregation topology, the feeder node is co-located with other ATM equipment and communicates with one or more core switches at remote locations. The switch aggregates the traffic from local ATM devices and pack ages it fo r high-speed communications over the c ore. Cisco MGX 8850 (PXM1E/PXM45) and Cisco MGX 8830 switches support feeder connections from Cisco MGX 8230, Cisco MGX 8250, Cisco MGX 8850 (PXM1), and Cisco IGX nodes.

A virtu al trunk provides a private v irtual network path through an independent network such as a pu blic ATM network. Using virtual trunks, Company A can establish a private virtual path between two sites using a publi c ATM network that supports this feat ure. From Company A’s poi nt of view, it has a private virtual pa th be t ween t he t wo sit e s th at c an s up por t mul tip le virt ua l ci rcui ts (VCs ) . Compa n y A’ s ne tw or k topology is completely private, as all communications are simply passed between edge devices, with no need for translation or routing. To accomplish this configuration, the virtual trunk supports the Service Specific C onnectio n Orien te d P ro to co l (S SCOP) ( virtual channel identifier [VCI = 5] ) , P r ivate Network-to-Network Interface (PNNI) (VCI = 18) and Integrated Local Management Interface (ILMI) (VCI = 16) signaling protocols.

Chapter 1 Preparing for Configuration

Unique Switch Name

Each switch must have its own name (which consists of up to 32 characters), unique within the ATM network. If you are adding a switch to a network, find out if the network administrator has established switch na m in g co nventions , an d find o u t w h ic h n ames have alre ad y be en used. It i s a go o d p ractice to name switches according to location, as such names convey both the switch identity and its location. The procedure for setting the name is described in the “Setting and Viewing the Node Name” section in

Chapter 2, “C on figu ri ng G e ne ra l S w i tch Features.”

IP Addressing Plan

An IP network addressing plan is required for switch management. IP network addressing is described in the “G u id elines for C r eat in g an I P A dd r ess Pl an ” section later in this chapter.

ATM Addressing Plan

An ATM net work a dd r essin g p lan i s crit ical for su cce s sfu l op erat io n of M G X sw i tch es in an ATM network. PNNI networks require unique ATM addresses on each switch. However, the PNNI protocol uses structured network addresses to logically group network devices and determine routes between devices. For PNNI networks, an ATM address plan is required.

Unique Device Identifier

Cisco products have an electronically retrievable identifier. This identifier is called the Unique Device Identifier (UDI) and consists of the Product Identifier (PID), the Version Identifier (VID), and the hardw a r e S e r i a l Number (SN ) . The UD I is pro g rammed at t he fact o r y a n d is st or e d i n non-volatile memory.

The UDI is used to identify specific equipment for inventory management, asset management, entitlement, business operations management, network implementation, and network management.

In network management, the UDI enables network administrators to easily track specific components in their net wo rk.

The advantage to using CWM or an SNMP manager is that you can use one program to simultaneously manage multiple devices. Also, CWM is the only management tool that can configure Service Class Templates (SCTs).

Physical Location of Cards and Lines in the Switch

Many conf igur ation fe atures depend on a spe cifi c hardwa re instal latio n conf igurat ion. The follo wing list provides some samples of how the software configuration depends on the hardware installation:

• The software for each switch sup ports a specific set of proce ssor cards and service module s.

• The softw are f o r e ach sw i tch ex pe cts to find each card ty p e in specifi c sl ot s.

Guidelines for Creating an IP Address Plan

• Redundant card configurat ions can req uire that redundant cards be placed in a specific relationship

to each o th er.

• Redundant line configurations can require additional hardware and require that redundant lines be

be placed in a s p eci fic rel ationship t o eac h o t he r.

Guidelines for Creating an IP Address Plan

MGX switches provide two IP a ddresses for LAN c onnectio ns. The b oot I P add ress enab les sw itch management when a PXM is in boot mode, which means that it has only loaded the boot software. The disk IP address enables switch management only after the switch has loaded and is running the runtime software.

A typical switch configuration requires either one or two IP addresses for LAN access. When the switch hosts a s ingle PXM ca rd, us e just one IP addre ss and ass ign it t o both t he boot an d disk IP a ddress op tions (more on t hi s later in th is s e ct io n) . When th e sw it ch u s es t wo P X M ca rd s, yo u can use on e or t wo I P addresses. Figure 1-5 shows a redun da nt PXM con figur at ion th at use s two IP addr ess e s. In a Cisco MGX 8850 (PXM1E/PXM45) or Cisc o MGX 8950 swit ch, th e red und ant P XM ca rd s wo uld be i n slots 7 and 8. In a Cisco MGX 8830 switch, the redundant PXM cards would be in slots 1 and 2.

The configuration shown in Figure 1-5 prov id e s t he following result s:

• Direct access to the active PXM using addres s B.B.B .B.

• Direct access to the stand by PXM card using addr ess A.A .A.A .

• The boot code on the s tandby PXM card can be upgraded without int errupting service o n the active

• You can perform additional procedures in backup boot mode on the standby card without

When dif fe re nt IP ad dres se s ar e use d f or the boo t an d di sk IP a ddr ess es, y ou can m ana ge t he act i v e P XM card and the switch using the disk IP address, which is B.B.B.B in Figure 1-5. You can also acces s th e standby PXM card using the boot IP address. When the same address is used for both the boot an d disk IP addresses, that address can be used only to manage the active PXM card.

When plan ni n g I P a dd res ses fo r y our s witch, use t he f ol low in g guid elines:

• If the switch has one PXM, make the boot and disk IP addresses the same.

• If the switch has two PXM cards and you want to minimize the number of IP addresses used, set

both boot IP addresses and the disk IP address to the same ad dress.

• If the switch has two PXM cards and you want to maximize your control options from remote

location s, as s ig n t h e sa m e b o ot I P ad dre s s to each PXM card, and assign a d iff eren t I P a dd r ess to the disk IP address.

• Be sure to define the default gateway IP address when defining the boot IP addresses.

• To minimize router configuration, choose boot, LAN, and default gateway IP addresses that are all

on the same subnet.

For instructions on setting boot and disk IP addresses, see the “Setting the LAN IP Addresses” section in Chapter 2, “Configuring General Switch Features.”

Guidelines for Creating a Network Clock Source Plan

Clock syn chroniz ation in an ATM network is very importa nt. If tw o switc hes hav e troub le synchro nizi ng their com m u ni cat io ns, traffic betw een the sw itches m ay h ave exc es sive er r ors o r li ne fa ilu r es. MGX switches support two methods of network clock synchronization:

• manual

• Network Clock Distribution Protocol (NCDP)

Both of these methods of clock synchronization are described in the sections that follow.

Note Manual clock configuration and NCDP configuration operate independently of one another. In other

words, you can configure both versions of network cl ock sourcing on your network. However, only one version can be enabled at a time. You cannot run your manual network clock configuration on your network while NCDP is running, and vice-versa. However, both configurations are stored in the disk database. Therefore, if you disable NCDP, the network reverts back to your original manual network clock configuration. If you enable NCDP on that same network at a later point, the network will revert back to t he p revi ous NCDP confi gur at io n.

Note On Cisco MGX 8850 (PXM1E) and Cisco MGX 8830 switches, clock source configuration is done on

the PXM1E card and passed to other nodes over PXM1E lines. On Cisco MGX 8850 (PXM45) and Cisco MGX 8950 switches, clock source configuration is done on a PXM45 card, and clock sourcing information is passed to other nodes over NNI trunks connected to service modules.

Planning for Manual Clock Synchronization

In manual clock source configurations, you need to configure a primary and secondary clock source, which are distributed thr oughout the network. All nodes ha ve an internal Strat um-3 clock that serves as a tertiary cloc k so ur ce . The secondary clo ck sou r ce tak es over if the primary clock sou r ce fails, an d the tertiary cl oc k sou r ce take s over i f th e se co nd ar y cl oc k sou r ce fai ls. I f n o clo ck so u rc es are configu r ed , the switch uses the internal Stratum-3 clock source. If only a primary clock source is configured, the internal Strat um-3 clo ck takes over in th e event of a primar y clock s o u rc e f ail ur e. Figure 1-6 shows an example network clock source topology.

In Fi gure 1-6, Switch 1 provides the master network clock source to the rest of the network and uses highl y accur a t e e xt e r n a l Building Integrated Timing System (BITS ) c lock source s to time its transmi ssio ns. These BI TS clo ck s o urces are T1 o r E 1 lin es w ith Stratum- 1, 2 , o r 3 clo ck si gn al s. Switch 1 uses one BITS line as the primary clock source and uses the secondary BITS source only if a failure occurs on the primary BITS line. If both BITS sources fail, the internal Stratum-3 clock takes over.

Note The PXM45 and PXM1E cards support T1 data (1.544Mbps) and E1 data (2.048Mbps) clock sources;

they do not support T1 or E1 sync clock sources. The PXM1 supports both T1 a nd E1 data types and an E1 sync (2.048MHz) line as a clock input.

Switch es 2 thr oug h 5 s ync hro nize to Swit ch 1 wi th th e mas ter c lock sig na l, whi ch th e y r ece iv e o ve r NNI trunks.

In Fi gure 1-7, Switches 1 and 2 have BITS devices. Switch 1 operates as the master and distributes its BITS cloc k sour ce o v er NNI trunk s to Swi tche s 2 t hrough 4. Swi tch 2 is th e st an dby m aste r an d rece i v es its primary clock signal over the NNI trunk from Switch 1. As long as Switch 1 and its primary BITS clock source are operating correctly, the entire network is synchronized to the BITS clock source from Switch 1.

In Fi gure 1-7, the seco nd ary clock sou r ce fo r th e ne two r k is t he S w it ch 2 BI TS clo ck s o u rc e, a nd a ll other sw it che s are configur ed to u se t he N N I tr u nk s f r om S w itc h 2 as t he ir s ec on d ar y c lo ck source. If Switch 1 or its BITS clock source fails, all the switches start using the clock signals from Switch 2 for network co m municati on s. This con fig uration pres e rve s n etw o rk sy ch ro n iz ation when either a clo ck source or a switch fails.

When a clock source fails and recovers, there are a couple of ways that the switch can revert back to the recovered c lo ck sou r ce. If th e r evert ive opti on is enabled , th e s w i tch ca n a ut o m ati ca lly r evert b ac k t o a recovered pr imary sou rc e fr om the se co ndar y so ur ce . I f fai lur es c au s e t he te rt iar y cl oc k sou r ce (t he intern a l S tr a t um - 3 c l ock) to take over, the switch w ill revert to eith er a r ec ove red pr imary o r r ecovered secondary clock source.

Note Regardless of the setting of the revertive option, the switch does revert back to a recovered primary clock

source if the sec ondary clock source fails . If the secondary clock source is functioning correctl y and the switch configuration does not support an automatic return to a recovered pr im ary clock source, you can manually switch back to the primary clock source by reconfiguring that clock source.

Note In releases prior to Release 5, the revertive option applied BITS clock sources and not to clock sources

from trun ks. Tertiary clock sou rces revert t o a r ec overe d p rim ary or secondary cl oc k in al l r el eas e s.

T o de ve lo p a netw or k cloc k sour ce plan, crea t e a topo logy dr a wi ng and id en tify whi c h swit ch es se rve a s active and standby master clock sources. For each switch that receives clock sources from other switches, indicate the lines that carry the primary and secondary clock signals.

Consider the following information when you create your manual network clock source plan:

• Master clock sources that are located near the center of the network minimize clock signal

propagation delay.

• BITS clock interfaces receive Stratum-3 or higher clock signals.

• Configuring a primary and secondary clock source provides fault tolerance.

• If both the prim ary and the sec ondar y external clock sou rces fai l, the switch uses an inte rnal

Strat um - 3 c l ock.

• When usi ng an ext ernal cloc k source and redun dant PXM cards, use a Y-cable to connect th at clock

source to the same clock port on both PXM cards. Do not run separate external clock sources to each card as this can produce timing problems.

Chapter 1 Preparing for Configuration

• If the switch is using its own internal Stratum-3 clock and a primary or secondary clock source

recove rs, th e s w i tc h w ill use the recovered clo ck sour ce.

• Primary and secondary BITS clocks can be configured after the switch is initialized. For more

informat io n , s ee the “Configuring Clock Sources” section in Chapter 2, “Configuring General

• Primary a nd sec ondary NNI trunk c locks must be c onfi gured after t he cards and li nes ar e conf igured.

Planning for NCDP Synchronization

The MGX switc hes suppo rt a Netw ork Clo ck Distri but ion Prot ocol (NC DP), whic h selec ts the bes t clock in your net work ba sed on yo ur conf igura tion , and autom atic ally co nfi gures t he path to that c lock for e ach node throughout your network. In an NCDP clock configuration, there are no primary and secondary clock sources. Instead, you configure several clock sources for the nodes in your network, from which NCDP selects the best (or root) and second best clock source for the network. Once NCDP has selected the root cl ock sou r ce, it is pr o pa gat ed to all the node s in t he n etw or k s o th at all noda l clocks ar e synchronized. If the root clock source fails, the sec ond best clock s ource becomes the root clock sour ce . If the second best clock source fails, NCDP selects the third best clock source to take over as the root clock source, and so forth.

If you want to use NCDP to s et up you r ne tw ork clo cks , you mu st f ir st en able NCDP, as describe d in the

“Managin g N CD P Clock Sou rc es ” sect ion in Chapter 9, “S w i tch O p er at in g Pro ce du r es.” Once you

enable NCDP on your node, it is automatically enabled on all NNI ports on the node. When NCDP is enabled, a r o ot cl oc k source i s au to m a ti cal ly select ed an d di str ibuted to al l n o de s in t he ne tw or k th at

have NCDP enabled. NCDP automatically selects an internal oscillator on one of the NCDP nodes to be the root clock source. Each NCDP node in the network is synchronized to this root clock reference. If you do not want the root clock source to be an internal oscillator, you can configure it to come from an exte rnal sour ce with the cnfncdpclksrc command, as described in the “Managing NCDP Clock Sources” section Ch ap te r 9, “Sw it ch O pe ra ti ng Pr o ced ur e s .”

NCDP us es the fo ll owing cr it er ia to find th e best ro ot cl oc k s ou rce for the n e t wor k:

• Priority (should be sufficient to find the root)

• Stratum level (sh ou l d b e sufficient as a ti e- br eaker)

• Clock s ou rce re fe re nc e

• ATM a ddr ess of the sw itch

Yo u can modif y t he cl oc k p r io r ity, stratum level o f th e B it s sou r ce, an d clo ck s o urce refere n ce t hro ug h the cnfncdpclksrc command, as described in the “Managi ng NCDP Cloc k S ou rces ” s ection in

Chapter 9, “Sw it ch O p er ati ng P r o ced u res .” Figure 1-8 shows an example NCDP network clo ck source topology. The numbers represe nt the p riority

of each network clock source, with 1 being the highest priority (or second best clock source) and 10 being the lowest priority. In this example, if the root clock source fails, the clock source with priority 1 takes over as the root clock. If the new root clock source with priority 1 fails, then the clock source with prior it y 2 take s over as the ro ot, an d s o fort h .

Consider the following information when you create your NCDP network clock source plan:

• You must enable NCDP on a per-node basis because m anual clocking is the defaul t method of clock

synchronization.

• Clock sour ces that ar e locate d near the cen ter of the ne twork minimiz e clock sig nal prop agat ion

delay.

• Once you enable NCDP, it is enabled on all NNI ports on the local switch by default. This includes

PNNI ports, IISP ports, and AINI ports.

• NCDP is disabled on virtual trunks by default.

• You can add clock sources to any UNI or clocking ports on the node.

• On every port w i th N C D P en ab led , NC D P establis he s a control V C t o car r y co nfigu r ati on a nd

networ k topology information between the conne cted nodes. On non-virtual trunk s, the cont rol VC is established by default on VPI 0, VCI 34. If you change the VPI/VCI within the limits of the minimum or maximum range, then the control VC will be established on the new VPI/VCI.

• BITS clock interfaces receive Stratum-3 or higher clock signals.

• NCDP supports a maximum of 200 nodes in an NCDP domain. If your network has more than 200

nodes, multiple, smaller NCDP domains should be established. Typically, NCDP domains follow PNNI peer group boundaries.

• When usi ng an ext ernal cloc k source and redun dant PXM cards, use a Y-cable to connect th at clock

source to the same clock port on both PXM cards. Do not run separate external clock sources to each card beca use th is can p r od u ce t imi n g p r oblems.

• If a failed clock source recovers, the switch will not revert to the recovered clock source unless you

re-add it to the node with the cnfncdpclksrc command.

• Primary and secondary BITS clocks can be configured after the switch is initialized. For more

informat io n , s ee the “Configuring Clock Sources” section in Chapter 2, “Configuring General

Starting a CLI Management Session After Initialization

After initialization, the PXM in the initialized slot becomes active. If a second PXM resides in the other slot, the active PXM initiates a runtime firmware load on the other slot. After the runtime firmware loads on the nonactive PXM, the card enters standby mode, ready to take control if the active card fails.

After you log in, the switch maintains your session for the default period of 10 minutes (600 seconds) after the last keystroke is entered. If the session is idle longer than 600 seconds, the session is terminated.

Chapter 2 Configuring General Switch Features

Step 1 Establish a configuration session using a user name with SUPER_GP privileges or higher. Step 2 Disable PNNI node operation by entering the following command:

mgx8850a.7.PXM.a> cnfpnni-node <node-index> -enable false

The node-index uniquely defines a logical PNNI node within the switch. Initially, there is just one logical PNNI node at the lowest PNNI level, and its inde x number is 1. If you add a high er lev el logical node t o the physical node, the first higher level will be numbered two, and the next higher level will be number three. Additional levels receive sequentially higher node index numbers.

During this genera l node conf iguration, you are setting the PNNI level and peer grou p ID for the lowest PNNI leve l, so r ep lace node-index with 1.

Note For ins t ru c t ions on creati ng logical nodes above th e lowest PNNI l evel , see Chapter 8,

“Managing PNNI Nodes and PNNI Routing.”

Step 3 Change the PNNI level and peer group ID with the cnfpnni-node comm an d as f o llow s:

mgx8850a.7.PXM.a> cnfpnni-node <node-index> [-pgId level:peerGroupID]

T o configure the lowest PNNI level, replace <node-index> with 1. Replace level with t he PN NI le v el you want to u se, an d re pl ace peerGroupID with the 13-byte peer group ID you want to use. For example:

mgx8850a.7.PXM.a> cnfpnni-node 1 -pgId 56:47.00.9181.0000.0100.0000.0000.00

Caution When installing new switches, you can assume that each default node address will be unique. When

PXM car ds ar e r ep a ir e d o r moved between switch es , how ever, it is poss i bl e th at two switches wi ll star t using the same node address. To prevent duplicate node addresses, use your own address plan, and check the node address whenever a PXM card is replaced or moved from one switch to another.

Step 1 Establish a configuration session using a user name with SUPER_GP privileges or higher. Step 2 Disable PNNI node operation by entering the following command:

mgx8850a.7.PXM.a> cnfpnni-node <node-index> -enable false

The node-index uniquely defines a logical PNNI node within the switch. Initially, there is just one logical PNNI node at the lowest PNNI lev el, and its index number is 1. If you add a higher level logical node to the physical node, the first higher level will be numbered two, and the next higher level will be number three. The node index is a reference to particular logical PNNI process in the node.

To set the PNNI node ID, use the following procedure.

Step 1 Establish a configuration session using a user name with SUPER_GP privileges or higher. Step 2 Disable PNNI node operation by entering the following command:

mgx8850a.7.PXM.a> cnfpnni-node <node-index> -enable false

The node-index uniquely defines a logical PNNI node within the switch. Initially, there is just one logical PNNI node at the lowest PNNI lev el, and its index number is 1. If you add a higher level logical node to the physical node, the first higher level will be numbered two, and the next higher level will be number three. The node index is a reference to particular logical PNNI process in the node.

The PNNI node ID is configured at the lowest PNNI level, so replace <node-index> with 1.

Note The node ID you enter at the lowest level is used for all levels. PNNI uses a modified version of

the lowest level node ID for upper level nodes.

mgx8850a.7.PXM.a> cnfpnni-node <node-index> [-nodeId PNNIlevel:160:atm-address]

To configure the lowest PNNI level, replace <node-index> with 1. Replace PNNIlevel wi th th e lowest PNNI leve l, a nd r ep lace atm-address with the 20-byte ATM address you want to use. For example:

mgx8850a.7.PXM.a> cnfpnni-node 1 -nodeId 56:160:47.00918100000100001a531c2a.00001a531c2a.01

Step 4 Enable PNNI node operation by entering the following command:

mgx8850a.7.PXM.a> cnfpnni-node <node-index> -enable true

Replace <node-index> with the value you used when disabling and reconfiguring the PNNI node.

Setting and Viewing the SPVC Prefix

Chapter 2 Configuring General Switch Features

The Cisco PNNI Ne twork Planning Guide for MGX and SES Products provides guideli nes for selecting the SPVC p re fix . T he S P V C p r efix i s th e ATM prefix that P N N I ad verti s es f o r all S PV C s an d S oft Permanent Virtual Paths (SPVP) on this node. The ATM address for each SPVC and SPVP is the combination of th e SPVC p r efix a nd a po r t i de nt ification num b er.

You can configure one SPVC node prefix per n ode. To set the SP VC prefix, use the following procedure.

Note Although the SPVC prefix is set to match the first 13 bytes of the PNNI node address by default,

changin g eit he r th e PNNI nod e ad dres s o r t he SP VC pr ef i x ha s no e f fec t on th e othe r se tti ng. I f the PNN I node ATM address and the SPVC pre f i x do not m atc h, the swit ch adve rtis es bot h pref i x es ins t ead of just one, and this a d ver tis i ng take s ad ditiona l b a n dw idth.

Note You can change the SPVC p r efix only when n o S PVCs or S P VPs have been defined. Once an SPV C has

been defined, you must delete all SPVCs before you can change the SPVC prefix. For information on deleting SPVCs th at termi nate on PXM 1E car ds, see the “Deletin g Connect io ns” s ection in Chapter 3,

“Provisioning PXM1E Communication Links.” For information on deleting SPVCs that terminate on

service m o du le s , r ef er t o the se rvice mod ul e d o c u men tation li s te d i n Table 1-1.

Step 1 Establish a configuration session using a user name with SUPER_GP privileges or higher. Step 2 Use the f ol low in g co m m an d to displa y th e curren t S PV C prefix :

mgx8850a.7.PXM.a> dspspvcprfx

The switch r esp o ns e is similar to the f o llowin g exa m ple:

mgx8850a.7.PXM.a> dspspvcprfx SPVC Node Prefix: 47.00918100000000001a531c2a

Tip If the SPVC pre f ix be g in s wit h 47 .009 181 000 000, t he SPVC pre f ix is p rob ably set to th e def aul t

value. To display the current PNNI node address, enter the dsppnni-node command.
