CH AP T E R 1 Command-Line Interface This chap ter provid es information for un derstanding and using the Cisco IOS command-line in terface (CLI) on the Catalyst 4500 series switch.
Chapter 1 Command-Line In terface How to Find Command Options How to Find Command Options This section provides an examp le of h ow to d isplay s yntax for a co mmand . The syntax can consist of o ptional o r required k eywords . To d isplay keywo rds for a command, enter a question mark (?) at the command prompt or after entering part of a comman d followed by a sp ace. The Catalyst 4500 series switch software disp lays a list of available key words along with a b rief des cription of the keyword s.

In this examp le, you must enter a channel group nu mber from 1 to 2 56.
Chapter 1 Command-Line Interface Understanding Command Modes Understanding Command Modes The Cis co IOS u ser interface on the Catalyst 4500 series switch has many different modes. Th e co mmand s that are available to you depen d on wh ich mode you are currently in . You can obtain a list of co mmand s available for each command mode b y enterin g a question mark (?) at the system p romp t. Wh en you s tart a ses sion on the Catalyst 450 0 series switch , y ou begin in user mode, often called EXEC mode.
Chapter 1 Command-Line In terface Using the No and Default Forms of Commands Table 1-3 Summary of Main Command Modes (continued) Co mmand Mode Access Method Prompt Subinterface co nfiguration From interface co nfiguration mode, specify a sub interface with an interface co mmand . Switch(config-subif)# To exit to g lo bal co nfiguration mod e, enter the exit command. ROM mo nitor From priv ileged EXEC mode, enter the relo ad EXEC command.
Chapter 1 Command-Line Interface Using the CLI String Search You can p erform three typ es of filtering: • Use the begin keyword to beg in o utput with the line that co ntain s a specified regular expressio n. • Use the include keywo rd to include o utput lines th at contain a specified regu lar expres sion. • Use the exclude keywo rd to ex clud e outp ut lin es that con tain a sp ecified regular expression . You can th en search th is filtered o utput at the --More-- prompts.
Chapter 1 Command-Line In terface Using the CLI String Search You can specify a ran ge of single-character patterns to match against command outp ut. For example, y ou can create a reg ular expression that match es a string co ntain ing o ne of th e fo llowing letters: a, e, i, o , or u. One and only one of these characters must exist in the string for pattern matching to su cceed. To sp ecify a range of single-character patterns, enclose th e single-character patterns in s quare b rack ets ([ ]).
Chapter 1 Command-Line Interface Using the CLI String Search You can create a mu ltiple-character regular expressio n con tainin g all letters , all dig its, all keybo ard ch aracters, or a combin ation of letters , digits, an d o ther keyb oard characters.
Chapter 1 Command-Line In terface Using the CLI String Search Alternation Alternation allows you to specify altern ative p atterns to match against a string. You sep arate the alternative patterns with a vertical bar (|). Exactly one of the altern atives can match the string. For example, the reg ular exp ression codex | telebit matches the string codex or the string telebit, but not bo th codex an d telebit.
Chapter 1 Command-Line Interface Saving Configuration Changes Parentheses for Recall As shown in the “Multipliers” section o n page 1-9, you use parentheses with mu ltiple-character regular exp ressions to multiply the occurrence of a pattern. You can also use p aren theses aroun d a single- or multiple-character p attern to remember a pattern for use elsewhere in the regu lar expression.
