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:

[^a-dqsv] This example matc he s anythin g exc ep t a rig ht sq uare br acket (]) o r th e l etter d :

[^\]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

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:

Table 1-4 lists the special characters that specify “multiples” of a regular expression.

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

1-7

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:

Chapter1 Command-Line Interface

• Config Sync AdminStatus— Signi fies w hat the u ser h as co nfigured f or thi s f eature at th at mom ent

–

The designated and nonde signated MSFCs are runni ng compa tible imag es

• No configuration mode is available on the CLI of the nonde signate d MSFC; EXE C mode is

available. Configuration of both MSFCs is made through the conso le or a Telnet session on the designated MSFC.

• The alt keyword is available an d re qu ire d ( see the “alt Keyword Usage ” se cti on on pa ge 1-9 for

When the Config Sync RuntimeStatus is in disabled mode, the following occurs:

• Configuration mode is available on the CLI of both MSFCs

• The alt keyword is available but optional

• The running and st art up configur ati ons are n ot sy nch ron ized

Table 1-6 shows the interface and global configuration commands that contain the alt keyword:
