Chapter 1 CLI Overview
Navigating Through CLI Commands
Note SPAN is only supported on external ports.
Navigating Through CLI Commands
To redisplay a command you previously entered, press the Up Arrow key. You can continue to press the
Up Arrow key to see more previously issued commands. Similarly, you can press the Down Arrow,
Right Arrow, Left Arrow, and Delete keys to navigate through the command history and to modify an
existing command string.
Getting Help
In any command mode, you can get a list of available commands by entering a question mark (?).
switch# ?
To obtain a list of commands that begin with a particular character sequence, type in those characters
followed immediately by the question mark (?). Do not include a space.
switch# co?
configure copy
To list keywords or arguments, enter a question mark in place of a keyword or argument. Include a space
before the question mark. This form of help is called command syntax help, because it reminds you
which keywords or arguments are applicable based on the commands, keywords, and arguments you
have already entered.
switch# config ?
terminal Configure the system from the terminal
Tip If you are having trouble entering a command, check the system prompt and enter the question mark (?)
for a list of available commands. You might be in the wrong command mode or using incorrect syntax.
Command Completion
In any command mode, you can begin a particular command sequence and immediately press the Tab
key to complete the rest of the command.
switch (config)# ro<Tab>
switch (config)# role <Tab>
switch (config)# role name
This form of help is called command completion, because it completes a word for you. If several options
are available for the typed letters, all options that match those letters are presented:
switch(config)# fc<Tab>
fcalias fcdomain fcs
fcanalyzer fcdroplatency fcns fctimer
fcc fcinterop fcroute
switch(config)# fcd<Tab>
fcdomain fcdroplatency
switch(config)# fcdo<Tab>
switch(config)# fcdomain
