Preface

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available: the Ci sco TAC website and the Cisco TAC Escalation Center. The type of support that you choose depends on t he priorit y of the proble m and the conditions stated in service contracts, when applicable.

We categorize Cisco TAC inquiries according to urgency:

• Priority level 4 (P4)—You need information or assistance conc erni n g Cisc o pr odu ct c apa bil ities,

product installation, or basic product configuration. There is little or no impact to yo ur business operations.

• Priority level 3 (P3)—Operational performance of the network is impaired, but most business

operations remain functional. You and Cisco are willing to commit resources during normal business hours to restore service to satisfactory levels.

• Priority level 2 (P2)—Operation of an existing network is severely degraded, or significant aspects

of your business operations are negatively impacted by inadeq ua te pe rform an ce of Cisc o pro duct s. You and Cisco will commit full-ti me resour ces dur ing normal business hours to resolve the situation.

Obtaining Technical Assistance

• Priority level 1 (P1)—An existing network is “down,” or there is a critical impact to your business

operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Cisco TAC Website

The Cisco TAC website provides online documents and tools to help troubleshoot and resolve technical issues with Cisco products and technologies. To access the Cisco TAC website, go to this URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC website. Some services on the Cisco TAC website require a Cisco.co m login ID and password. If you have a valid service contract but do not have a login ID or password, go t o th is URL to register :

http://tools.cisco.com/RPF/register/register.do

If you are a Cisco.com registere d user, and you cannot resol ve your tech ni cal issues by using the Cisco TAC website, you can open a case online at this URL:

http://www.cisco.com/tac/caseopen

If you have Internet acc ess , we re com mend tha t y ou open P3 and P4 case s onl ine so that y ou ca n fu lly describe the situation and attach any necessary files.

Cisco TAC Escalation Center

OL-3354-01

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.

Chapter 1 Comman d-Line Interface

Using the No and Default Forms of Commands

Almost every configuration command has a no form. In general, enter the no form to disable a function. Use the command without the ke y w o rd no to reenable a disabled function or to enable a function that is disabled by default. For example, IP rou ting is enab led by default. To disable IP routing, specify th e no ip routing command and specify ip routing to reenable it. This publication provides the complete syntax for the configuration comm ands an d describ es what the no fo rm of a comma nd does.

Configuration commands can have a default form. The default form of a command returns the command setting to its default. Most commands are disabled by default, so the default form is the same as the no form. However, some co mm an ds ar e en ab led b y de f au lt and have variab les set to certain default values. In these cases, the default form of the command enables the command and sets variables to their default values. This publication describes what the default form of a c omma nd doe s if t he com ma nd is not th e same as the no form.

Using the CLI String Search

The pattern in the comm and output is refer red to as a str ing. The CLI string search featu re allows you to search or filter a ny show or more command outp ut and allows you to sear ch and filter at --More- - prompts. This feature is useful when you need to sort though large amou nts of output, or if you want to exclude output that you do not ne ed to see.

With the search function, you can begin unfiltered output at the first line that contains a regular expression you specify. Y ou can then specify a maximum of one filter per command or start a new search from the --More -- prom pt .

A regular expression is a patt ern (a phr ase , num be r, or more c ompl ex pat tern ) sof twar e use s to ma tc h against show or more command output. Regular expressions are case sensitive and allow for complex matching requiremen ts. Examp les of simple regular expressio ns are Ser ial, misses, and 138. Ex ample s of complex regular expressions are 00 210..., ( is ), and [Oo]u tput.

You can perform thr ee t y pes of filterin g:

• Use the begin keyword to begin output with the l ine t hat con tai ns a spe cified r egular expr ession .

• Use the include keyword to include output line s th at co ntain a sp eci fied regula r expr essio n.

• Use the exclude keyword to excl ude out p ut l ine s tha t con t ain a spec ified r egular expressi o n.

You can then search this filtered outpu t at the --M ore-- prom pts.

Note The CLI string search func tion doe s not allow you to search or filter backward through previous output;

filtering cannot be specified using HTTP access to the CLI.

Regular Expressions

A regular expression can be a single character that matches the same single character in the command output or multiple characters that match the same multiple characters in the command output. This section describes how to create both single-character patterns and multiple-character patterns and how to create more complex regular expressions using multiplie rs, alterna tion, anc horing, a nd parenthe ses.

Using the CLI String Search

Single-Character Patterns

The simplest regular expression is a single character that matches the same single character in the command output. You can use any letter (A-Z, a-z) or digit (0-9) as a single-character pattern. You can also use other keyboard characters (such as ! or ~) as single-character patterns, but certain keyboard characters have spec i al m e an in g w h en us e d in r egul ar expr essi o ns. Table 1-3 lists the keyboard characters with special meaning.

Table 1-3 Characters with Special Meaning

Character Special Meaning

. Matches any sin gle ch aract er, includ ing whi te spa ce. * Matches 0 or more sequenc es of th e pattern . + Matches 1 or more sequences of the pattern. ? Ma tch es 0 or 1 occurre nces of the pattern . ^ Match es the beginnin g of the string . $ Matches the end of the string. _ (underscore ) Matches a comma (,), le ft b ra ce ({ ), ri g ht br ace ( }), lef t pa rent hesi s ( ( ),

To enter these special characters as single-character patterns, remove the special meaning by preceding each character with a backslash (\). Th ese e xample s are sin gle-cha racter p atterns ma tching a dollar sig n, an underscore, and a plus sign, respectively.

Yo u ca n spe cif y a ra nge o f s ingl e-c har act er patt erns to match a gainst co mm an d o utput . For exam ple , you can create a regular expression that ma tche s a stri ng cont ai ning on e of the following lett ers: a, e, i, o, or u. One and only one of these characters must exist in the string for pattern matching to succeed. To specify a range of single-character patterns, enclose the single-character patterns in square brackets ([ ]). For exampl e,

[aeiou]

matches any one of the five vowels of the lowercase alphabet, while

[abcdABCD]

matches any one of the first four letters of the lower- or uppercase alphabet. Yo u can si mplify r anges by e nter ing only t he e nd poin ts of the range sepa ra ted by a d ash ( -). Sim pli fy

the previous range as follows:

[a-dA-D]

To add a dash as a single-character pattern in your range, include another dash and precede it with a backslash:

[a-dA-D\-]

You can also include a right square bracket (]) as a single-character pattern in your range. To do so, enter the following:

1-6

[a-dA-D\-\]]

Chapter 1 Comman d-Line Interface

The previous example m a tches any on e of the first fou r lett ers o f th e lower- or up perc ase al ph ab et, a dash, or a right square bra cket.

You can reverse the matching of the range by including a caret (^) at the start of the range. This example matches any letter except the ones listed:

[^\]d]

Multiple-Character Patterns

When creating regular expressions, you can also specify a pattern containing multiple characters. You create multiple-character regular expressions by joining letters, digits, or keyboard characters that do not have special meaning. For example, a4% is a multi ple-cha racte r regular expressi on. Put a backsl ash in front of the keyboar d ch arac t ers t h at h ave specia l m eani n g wh en yo u want to r em ove their spe cia l meaning.

With multiple-character patterns, order is important. The regular expression a4% matches the character a followed by a 4 followed by a % sign. If the string does no t have a4%, in that order, pattern m atc hing fails. This multiple-character regular expression

Using the CLI String Search

Multipliers

uses the special meaning of the period character to match the letter a followed by any single character. With this example, the strings ab, a!, or a2 are all valid matches for the regular expression.

You can remove the special meaning of the period character by putting a backslash in front of it. In the following expression

a\.

only the string a. m atche s this regul ar expression. Yo u can cr eate a mu ltiple-c har acter regular expre ssion cont aining a ll letter s, all di gits, all keyboard

characters, or a combina tion of l etters , digits , and othe r keyboard ch aract ers. Th ese examp les ar e all valid regular expressions:

This example matches any numbe r of occurr ence s of the lett er a, inc luding none:

Catalyst 6500 Series Switch MSFCCommand Reference—Release 12.1(13)E

Using the CLI String Search

This pattern requires that at least one letter a in the string is matched:

This pattern ma tche s th e string bb or b ab:

ba?b

This string matche s any num be r of a sterisk s (* ): \** To use multipliers with multiple-character patterns, you enclose the pattern in parentheses. In the

following example, the pattern matches any number of the multiple-character string ab:

(ab)*

As a more complex example, this pattern matches one or more instances of alphanumeric pairs (but not none; that is, an emp ty stri ng is not a ma tch ):

([A-Za-z][0-9])+ The order for matches using multiplier s (*, +, or ?) is t o put the longest co nstruct fi rst. Nested co nstructs

are matched from outs ide to insi de. Conca tenate d const ructs ar e match ed beginning at the left side of the construct. Thus, the regular expression matches A9b3, but not 9Ab3 because the letters are specified before the numb er s.

Chapter1 Command-Line Interface

Alternation

Anchoring

Alternation allows you to specify alternative patterns to match against a string. You separate the alternative patterns with a vertical bar (|). Exactly one of the alternatives can match the string. For example, the regula r expr es sio n

codex | tel ebit matches the strin g cod ex or t he st rin g teleb it, but not both co dex and t elebi t.

Yo u can ma tch a r egular expression pa tt ern agai nst th e b eginning or the en d of the string. T hat is, yo u can specify that the beginni ng or e nd of a strin g co ntai n s a speci fic pattern . You “anchor” these regular expressions to a portion of the string usin g the specia l characters shown in Table 1-5.

Table 1-5 Special Characters Used for Anchoring

Character Description

^ Ma tches t he beginnin g of the string . $ Matches the end of the string.

This regular expression mat ches a stri ng o nl y if the string st art s wi th a bcd :

1-8

^abcd

In contrast, this expression is in a ra nge that ma tches any singl e letter, as long as it is not the lette rs a, b, c, or d:

[^abcd]

Catalyst 6500 Series Switch MSFCCommand Reference—Release 12.1(13)E

OL-3354-01

Chapter 1 Comman d-Line Interface

With this example, the regular expression matches a st ring that ends with .12:

$\.12

Contrast these anchoring characters with the special character underscore (_). The underscore matches the beginning of a string (^), the end of a string ($), parentheses ( ), space ( ), braces { }, comma (,), or underscore (_). With the underscore character, you can specify that a pattern exist anywhere in the string.

For example:

_1300_

matches any string that has 1300 somewhere in the string. The string’s 1300 can be preceded by or end with a space, brace, comma, or underscore. For example:

{1300_

matches the regular expression, but 21300 and 13000 do not. Using the underscore cha racter, you can repla ce long regular expression list s, such as the fol lowing:

^1300$ ^1300(space) ( spac e)130 0 { 130 0, , 1300 , {1 300} , 1300, ( 1300

with

_1300_

Using the CLI String Search

Parentheses for Recall

As shown in the “Multipliers” section on pa ge 1-7, you use parentheses with multiple-character regular expressions to multiply the occurrence of a pattern. You can also use parentheses around a single- or multiple-character pattern to remember a pattern for use elsewhere in the regular expression.

To create a regular expressi on that rec alls a previous patter n, you use pare ntheses to indicate a remembered specif ic p attern and a b ackslash (\) foll owe d by an integ er to reuse the remembe red pattern . The integer specifies the occurrence of the parentheses in the regular expression pattern. If you have more than one remembered pa ttern in yo ur regular expressi on, then \1 in dicates the first remember ed pattern, \2 ind ica tes the sec ond rem embe re d pat tern, a nd so on .

This regular expression uses parent heses for re call:

a(.)bc(.)\1\2

This regular expressi on ma tc hes a n a fol lowed by any char ac te r ( cal l i t c hara c ter 1) , foll owed by bc followed by any character (character 2), followed by character 1 again, followed by character 2 again. The regular e xpress ion can ma tch aZbcT ZT. The software remembers that charac ter 1 is Z and charac ter 2 is T and then uses Z and T again later in the regular expression .

alt Keyword Usage

When you enable hig h-availability re du ndancy, every configuration command executed on the designated MSFC is sent to the nondesign ated MSFC . Also , th e runni ng configura tion sync hro niz ation is updated when you enter the copy source running-config command on the designated M SFC.

Using the CLI String Search

The two states for th e configur ation synch roni zatio n are as follows:

To configure both MSFCs from a single console, enter the alt keyword to specify an alternate configuration. When sp ecifying the al ternate conf iguration, the co nfig uration that i s specif ied before the alt keyword relates to the MSFC on the supervisor engine in slot 1 of the switch; the configuration that is specified after the alt keyword relates to the M SFC on the su pe rvisor eng ine in slot 2.

Note You must enter the alt keyword when you enable Config Sync AdminStatus.

When you enable the Config Sync RuntimeStatus, the following occurs:

Usage Guidelines This comm a nd appl ies only to pl atf orm s th at u se a so ft ware c onfigurat ion r egister.

The lowest four bits of the configuration register (bits 3, 2, 1, and 0) form the boot field. The boot field determines if the router boots manually, from ROM, or from Flash or the network.

To change the boot fiel d value and leave all o the r bits set to their default valu es, fo llow these guidelines:

• If you set the configuration registe r boot field value to 0x0, you must boo t the operatin g system

manually with the boot command.

• If you set the configuration regist er boot field value to 0x1, the router boots using the default ROM

software.

• If you set the configuration register boot field to any value from 0x2 to 0xF, the router uses the boot

field value to form a de fault boot filen ame fo r boo tin g f rom a netwo rk server.

For more information about the configuration register bit settings and default filenames, see the appropriate ro ut er h ar dware inst a llat ion guid e.

Usage Guidelines The al t keyword is used to spec ify an alter nate co nfiguration a nd is used in th e following:

secondary (Optional) Specifies that th e configured addr ess is a secondary IP address. If th is

keyword is omitted, the configured address is the primary IP address.

Release Modification

12.1E This command was introduced on the MSFC.

[no] ip address ip-address mask [secondary] alt [no] ip address ip-address mask [secondary]

An interface can have one primary IP address and multiple secondary IP addresses. Packets generated by the Cisco IOS software always use the primary IP address. Therefore, all routers and access servers on a segment should shar e the same p rima ry net work n um ber.

2-10

Hosts can determine subnet masks using the Internet Control Message Protocol (ICMP) Mask Request message. Routers respond to this re quest with an ICMP Mask Reply message.

You can disable IP processing on a particular interface by removing its IP address with the no ip address command. If the software detects anoth er host using one of its IP addr esses, it will print an er ror message on the console.

The optional keyword secondary allows you to specify an unlimited numbe r of seconda ry addr esses. Secondary addresses are t reated like prim ary ad dresses, except the system never generates dat agrams other than routing updates with secondary source addresses. IP broadcasts and ARP requests are handled properly, as are interface routes in the IP routing table.

Secondary IP addresses can be used in a variety of situations. The following are the most common applications:

Catalyst 6500 Series Switch MSFCCommand Reference—Release 12.1(13)E

OL-3354-01

Chapter 2 Catalyst 6500 Series Switch MSFC Commands

• There may not be enough hos t addresse s for a particul ar network segment . For example, your

subnetting allows up to 254 hosts per logical subnet, but on one physical subnet you need to have 300 host addresses. Using secondary IP addresses on the routers or access servers allows you to have two logical subnets u sin g one p hysical su bnet.

• Many older netw orks were b uilt using Le vel 2 bridges. The jud icious use of seco ndary addresses can

aid in the transition to a subnetted, router-based network. Routers on an older, bridged segment can be easily made aware that there are many subnets on that segment.

• T w o subnets of a single network might otherwise be separated by another network. This situation is

not permitted when subnets are in use. In these instances, the first network is extended, or layered on top of the sec ond ne twor k us ing secon da ry ad dre sses.

Note If any router on a network segment uses a secondary address, all other devices on that same

segment must also use a secondary address from the same network or subnet. Inconsistent use of secondary ad dresse s o n a network segment ca n very q uick ly c ause rout ing loop s.

Note When you are routing Open Shortest Path First (OSPF), ensure that all secondary addresses

of an interface fall into the same OSPF area as the primary addresses.

ip address

To transparently bridge IP on an interface, you must do two things:

• Disable IP routing (s pec ify no ip routing).

• Add the interface to a brid ge group . (See the bridge-group co mmand.)

To concurrentl y route a nd transpa rently bridge IP on a n interface , see the bridge crb command.

Examples In the following exampl e, 13 1. 108 .1. 27 i s the prim ar y add re ss and 19 2. 31. 7.17 an d 1 92. 31.8. 17 are

Table 2-1 Encapsulation Types

Encapsulation Type Description

arpa For Ethernet interfaces only—U se Novell’s Ethernet_II e ncaps ul ation .

This encapsulation is recommended for networks that handle both TCP/IP and IPX traffic.

hdlc For Serial interfaces only—Use HDLC encapsulation. novell-ether For Ethernet interfaces only—Use Novell’s “Ethernet_802.3”

encapsulation. This encapsulation consists of a standard 802.3 Media Access Control (MAC) header follow ed dir ec tly by the IPX header with a checksum of FFFF. It is the default encapsulation used by all versions of NetWare up to and including Version 3.11.

novell-fddi For FDDI interfaces only—Use Novell’s “FDDI_RAW” encapsulation.

This encapsulat ion consist s of a stan dard FDDI MAC header followed directly by the IPX header with a checksum of 0xFFFF.

sap

• For Ethernet interfa ces— Us e N ovell’s Ethernet_802. 2

encapsulation.This enc aps ulat ion consi sts of a standa rd 80 2.3 MAC header followed by an 802.2 LLC header. This is the default encapsulation used by Ne tWare Version 3.12 and 4. 0.

• For T oken Ring interfaces—This encapsulation consists of a standard

802.5 MAC header fo llowed by an 8 02. 2 L L C h eade r.

• For FDDI interface s—This encapsulatio n consists of a standard FDDI

MAC header followed by an 802.2 LLC header.

snap

• For Ethernet interfa ces— U se Novell Et hern et _ Snap en cap sul atio n.

This encapsulati on consist s of a standa rd 802.3 MA C header follo wed by an 802.2 SNAP LLC header.

• For Token Ring and FDDI interfaces—This encapsulation consists of

a standard 802.5 or FDDI MAC header followed by an 802.2 SNAP LLC header.

The ipx network command a llows you to configu re a sin gle logi cal ne twork on a phy sica l ne twork o r more than one logical network on the same physical network (network cable segment). Each network on a given interface must have a different encapsulation type.

Note Yo u ca nnot configu re m ore th an 20 0 I PX i nte rface s on a rout er usi ng the ipx ne twork

command.

The first network you configure on an interface is considered to be the primary network. Any additional networks are considered to be secondary networks; these must include the secondary keyword.

NLSP does not suppo rt se cond ar y net works. You must use subinterfaces in or de r to u se mu ltiple encapsulati ons w ith N LS P.

Catalyst 6500 Series Switch MSFCCommand Reference—Release 12.1(13)E

OL-3354-01

Chapter 2 Catalyst 6500 Series Switch MSFC Commands

Note When enabling NLSP and configuring multiple encapsulations on the same physical LAN

interface, you must use subinterfac es. You cannot use secondary networks.

Yo u can co nfigure an IPX network on any supported int erface as long as all the networks on t he same physical interface use a distin ct en capsulat ion type . For example, you ca n configure up t o four IPX networks on a singl e Et her net cabl e b eca use E the rnet su pport s f our e ncap sul atio n typ es.

The interface proc esses only pack ets with the correct en capsulation an d the correct netw ork number . IPX networks using ot her e nca psula tio ns can be pre sen t on t he p hysi cal net work. The on ly e ffect o n the router is that it uses some processing time to examine pack ets to determine whether the y have the corr ect encapsulation.

All logical networks on an interf ace share the same set of conf iguratio n parameter s. Fo r e xample, if you change the IPX RIP update tim e on an inter face, you chang e it for all net works on that int erface.

When you define multiple logical networks on the same physical network, IPX treats each encapsulation as if it were a separate physical network. This means, for example, that IPX sends RIP updates and SAP updates for eac h l ogic al netwo rk.

The ipx network comma nd is us ef ul wh en m igra ting f rom one type of en cap sul atio n to ano ther. If you are using it for this purpose, you should define the new encapsul ation on th e primar y network.

To delete all networks on an interface, use the following command:

no ipx network

Deleting the primary network with the following command also deletes all networks on that interface. The argument number is t he nu mber o f t h e pri m ar y ne twork.

To delete a secondary network on an interface, use one of the following commands. The argument number is the number of a secondary network.

no ipx network number no ipx network nu mb er encapsulation encapsulation-typ e

Novell’s FDDI_RAW encapsulation is common in bridged or switched environments that connect Ethernet-based Novell end hosts via a FDDI ba ckbone . Packets with FDDI _RAW encapsulation are classified as Novell packets, and a re not automatically bridged when you enable both bridging and IPX routing. Additionally, you cannot configure FDDI_RAW encapsulation on an interface configured for IPX autonomous or SSE switchi ng. Similarly, you cannot enable IPX autonomou s or SSE switching on an interface configured with FDDI_RAW encapsulation.

With FDDI_RAW encapsulation, plat fo rm s th at d o n ot us e CBUS ar ch i tec ture su ppo rt fas t s wi tchi n g. Platforms using CBUS a rchi te ctur e sup por t on ly p roce ss swi tchin g of novell-fddi packets received on an FDDI interface.

including router port s an d VL ANs , y ou c an configure no ndefault MTU values o n a pe r-interface basi s. For a complete list of modules that d o not support jumbo frames, ref er to the Catalyst 6500 Series Switch

Cisco IOS Software Configuration Guide. Changing the MTU value with the mtu command can affect values for the protocol-specific versions of

the command (for example, the ip mtu command). If the values spec ified wi th th e ip mtu command is the same as the value specif ied with the mtu co mmand, an d you ch ange the val ue for th e mtu command, the ip mtu value automatically match es the ne w mtu comman d value. Howe v er, changing the v a lues f or the ip mtu command has no effect on the value for the mtu comm and.

Examples This example shows how to specify an MTU of 1800 bytes:

Router(config)# interface fastethernet 5/1 Router(config-if)# mtu 1800

SNMP notifications can be sent as traps or inform requests. This command enables both traps and inform requests for the specified notification types. T o specify whether the notifications should be sent as traps or informs, use the snmp-server host [traps | informs] command.

If you do not enter an snmp-server enable traps command, no notifica tions controlled by this command are sent. In or de r to c onfigure the r oute r t o s end t he se SN M P n otificati on s, you mu st e nte r at le as t on e snmp-server enable traps command. If you enter the command with no keywords, all notification types are enabled. If you enter the command with a keyword, only the notification type related to that keyword is enabled. In order to enable multiple types of notifications, you must issue a separate snmp-server enable traps command for each notification type and notification option.

The snmp-server enable traps command is used in conjunction with the snmp-server host comm an d. Use the snmp-serv er ho st co mmand to specif y which ho st or hosts r ecei ve SNMP notif icati ons. In orde r to send notifications, you must configure at least one snmp-server host command.

Valid values for the notification-option are as follows:

snmp-server enable traps

• atm pvc [interval seconds] [fail-interval seconds]

–

The optional interval seconds specifies the minimum period between successive traps, in the range from 1 to 3600. Generation of PVC traps is da mpened by the notif ication interv al in or der to prevent trap storms. No traps are sent until the interval lapses.

–

The optional fail-interval seconds specifies the minimum period for storing the failed time stamp, in the range fr om 0 to 3600.

• dlsw [circuit] [tconn]

–

The optional circuit enables SNMP DLSw circuit traps.

–

The optional tconn enables SNMP DLSw peer transport connection traps

• isdn [call-information] | [layer2]

–

The optional call-information enables an SNMP ISDN call information notification for the ISDN MIB subsystem.

–

The optional layer2 enables SNMP ISDN Layer 2 transition traps.

• snmp [authenticatio n] | [warmstart]

–

The optional authentication enables the authentication trap.

–

The optional warmstart enables the warmStart trap.

Use of the authentication keyword produces the same effect as not using t he authentication keyword. Both the snmp-server enable traps snmp and snmp-server enable traps snmp authentication f orms of this command will globally enable (or, if using the no form, disable) the following SNMP traps:
