Before You Begin
This chapter prepares you to configure switches from the CLI. It also lists the information you need to have before you begin, and it describes the CLI command modes.
This chapter includes the following sections:
•About the Switch Prompt
•About the CLI Command Modes
•Understanding CLI Command Hierarchy
•Navigating Through CLI Commands

•Using Valid Formats and Ranges
About the Switch Prompt
If you are connected to the console port when the switch boots up, you see the output show in Figure 2-1:
Note Refer to the Cisco MDS 9200 Series Hardware Installation Guide or the Cisco MDS 9500 Series Hardware Installation Guide for installation and connection instructions.
Once the switch is powered on successfully, you see the default switch prompt (switch#). You can perform embedded CLI operations, access command history, and use command parsing functions at this prompt. The switch gathers the command string upon detecting an Enter (CR) and accepts commands from a terminal.
Figure 2-1 Output When a Switch Boots Up
About the CLI Command Modes
Switches in the Cisco MDS 9000 Family have two main command modes—user EXEC mode and configuration mode. The commands available to you depend on the mode you are in. To obtain a list of available commands in either mode, type a question mark (?) at the system prompt.
Table 2-1 lists and describes the two commonly used modes, how to enter the modes, and the resulting system prompts. The system prompt helps you identify which mode you are in and, hence, which commands are available to you.
Table 2-1 Command Modes
Mode
|
Description of Use
|
How to Access
|
Prompt
|
EXEC
|
Enables you to temporarily change terminal settings, perform basic tests, and display system information.
Note Changes made in this mode are generally not saved across system resets.
|
At the switch prompt, enter the required EXEC mode command.
|
|
Configuration mode
|
Enables you to configure features that affect the system as a whole.
Note Changes made in this mode are saved across system resets if you save your configuration. See the "Saving a Configuration" section.
|
From EXEC mode, enter the configure terminal command.
|
|
You can abbreviate commands by entering just enough characters to make the command unique from other commands. For example, you can abbreviate the configure terminal command to conf t.
Understanding CLI Command Hierarchy
The CLI commands are organized hierarchically, with commands that perform similar functions grouped under the same level. For example, all commands that display information about the system, configuration, or hardware are grouped under the show command, and all commands that allow you to configure the switch are grouped under the config command. Figure 2-2 illustrates a portion of the config terminal command hierarchy.
Figure 2-2 CLI Command Hierarchy Example
To execute a command, you enter the command by starting at the top level of the hierarchy. For example, to configure a Fibre Channel interface, use the config terminal command. Once you are in configuration mode, issue the interface command. When you are in the interface submode, you can query the available commands there.
The following example shows how to query the available commands in the interface submode:
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# interface fc1/1
Interface configuration commands:
channel-group Add to/remove from a port-channel
exit Exit from this submode
fcdomain Enter the interface submode
fspf To configure FSPF related parameters
no Negate a command or set its defaults
shutdown Enable/disable an interface
switchport Configure switchport parameters
EXEC Mode Options
When you start a session on the switch, you begin in EXEC mode. Based on the role or group to which you belong, you have access to limited commands or to all commands (see the "Role-Based Authorization" section). From the EXEC mode, you can enter configuration mode. Most of the EXEC commands are one-time commands, such as show commands, which display the current configuration status. Here is a list of EXEC mode commands:
attach Connect to a specific linecard
bios BIOS related command
callhome Callhome commands
cd Change current directory
clock Manage the system clock
config Enter configuration mode
copy Copy from one file to another
debug Debugging functions
dir Directory listing for files
discover Discover information
exit Exit from this submode
fctrace Trace the route for an N-Port.
find Find a file below the current directory
init Initialize internal disk
install Non-disruptive upgrade for system and linecards
mkdir Create new directory
no Disable debugging functions
purge Deletes unused data
pwd View current directory
reload Reboot the entire box
rmdir Remove existing directory
run-script Run shell scripts
send Send message to all the open sessions
setup Run the basic SETUP command facility
show Show running system information
sleep Sleep for the specified number of seconds
system System management commands
tail Display the last part of a file
telnet Telnet to another system
terminal Set terminal line parameters
traceroute Trace route to destination
undebug Disable Debugging functions (See also debug)
write Write current configuration
zone Execute Zone Server commands
Configuration Mode
Configuration mode allows you to make changes to the existing configuration. When you save the configuration, these commands are preserved across switch reboots. Once you are in configuration mode, you can enter interface configuration mode, zone configuration mode, and a variety of protocol-specific modes. Configuration mode is the starting point for all configuration commands. When you are in configuration mode, the switch expects configuration commands from the user.
The following example shows output from the config terminal command:
Enter configuration commands, one per line. End with CNTL/Z.
Configuration Mode Commands and Submodes
The following is a list of configuration mode commands:
Enter configuration commands, one per line. End with CNTL/Z.
arp [no] remove an entry from the ARP cache
boot Configure boot variables
callhome Enter the callhome configuration mode
clock Configure time-of-day clock
fcalias Fcalias configuration commands
fcanalyzer Configure cisco fabric analyzer
fcc Configure FC Congestion Control
fcdomain Enter the fcdomain configuration mode
fcdroplatency Configure switch or network latency
fcinterop Interop commands.
fcns Name server configuration
fcroute Configure FC routes
fcs Configure Fabric Config Server
fctimer Configure fibre channel timers
in-order-guarantee Set in-order delivery guarantee
interface Select an interface to configure
line Configure a terminal line
logging Modify message logging facilities
no Negate a command or set its defaults
power Configure power supply
poweroff Poweroff a module in the switch
qos Configure priority of FC control frames
radius-server Configure RADIUS related parameters
snmp-server Configure snmp server
span Enter SPAN configuration mode
ssh Configure SSH parameters
switchname Configure system's network name
system System config command
trunk Configure Switch wide trunk protocol
username Configure user information.
vsan Enter the vsan configuration mode
wwn Set secondary base MAC addr and range for additional WWNs
zone Zone configuration commands
zoneset Zoneset configuration commands
Configuration mode, also known as terminal configuration mode, has several submodes. Each of these submodes places you deeper in the prompt hierarchy. When you type exit, the switch backs out one level and returns you to the previous level. When you type end, the switch backs out to the user EXEC level. You can also type Ctrl-Z in configuration mode as an alternative to typing end.
Note When in configuration mode, you can enter an EXEC mode command followed by a Ctrl-z. In response,
the switch returns to the EXEC level. The entered command is then executed at the EXEC level
The following example executes the copy running-config startup-config command from configuration mode, if you press Ctrl-z, instead of Enter.
switch(config)# copy run start

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 (?).
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.
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.
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:
fcanalyzer fcdroplatency fcns fctimer
switch(config)# fcdo<Tab>
Using the no and Default Forms of Commands
You can issue the no form of any command to perform the following actions:
•Undo a wrongly issued command.
If you issue the zone member command, you can undo the results:
switch(config)# zone name test vsan 1
switch(config-zone)# member pwwn 12:12:12:12:12:12:12:12
switch(config-zone)# no member pwwn 12:12:12:12:12:12:12:12
WARNING: Zone is empty. Deleting zone test. Exit the submode.
•Delete a created facility
If you want to delete a zone that you created:
switch(config)# zone name test vsan 1
switch(config-zone)# exit
switch(config)# no zone name test vsan 1
You cannot delete a zone facility called test while residing in it. You must first exit the zone submode and return to configuration mode.
Entering CLI Commands
You can configure the software in one of two ways:
•You can create the configuration for the switch interactively, working at the CLI prompt.
•You can create an ASCII file containing a switch configuration and then load this file on the required system. You can then use the CLI to edit and activate the file (see the "Working with Configuration Files" section).
Viewing a Configuration
You can view the ASCII form of the configuration file when required. To view the current configuration tree from the EXEC prompt, issue the show running-config command. If the running configuration is different from the startup configuration, issue the show startup-config command to view the ASCII version of the current startup configuration that was used to boot the switch.
You can gather specific information on the entire switch configuration by issuing the relevant show commands. Available show commands for each feature are listed at the end of each chapter. Examples 2-1 to 2-3 display a few show command examples.

Using the File System
The file system on a switch in the supervisor module provides a number of useful commands to help you manage software image files and configuration files.
You have access to two directories within the internal bootflash: file system. They are volatile: (temporary storage, also the default) and bootflash: (permanent storage). Files in temporary storage (volatile:) are erased when the switch reboots.
Setting the Current Directory
The cd command changes the current directory level to a specified directory level. CLI defaults to the volatile: files system. This command expects a directory name input.
Tip Any file saved in the volatile: file system will be erased when the switch reboots.
The syntax for this command is cd directory name
This example changes the current directory to the mystorage directory that resides in the slot0 directory:
switch# cd slot0:mystorage
This example changes the current directory to the mystorage directory that resides in the current directory.
If the current directory is slot0:mydir, this command changes the current directory to
slot0:mydir/mystorage.
Displaying the Current Directory
The pwd command displays the current directory location. This example changes the directory and displays the current directory.
Listing the Files in a Directory
The dir command displays the contents of the current directory or the specified directory. The syntax for this command is dir directory or file name
This example shows how to list the files on the default volatile: file system:
Usage for volatile: filesystem
Creating a New Directory
The mkdir command creates a directory at the current directory level or at a specified directory level.
The syntax for this command is mkdir directory name
This example creates a directory called test in the slot0 directory.
This example creates a directory called test at the current directory level.
If the current directory is slot0:mydir, this command creates a directory called slot0:mydir/test.
Deleting an Existing Directory
The rmdir command deletes an existing directory at the current directory level or at a specified directory level. The directory must be empty to be deleted.
The syntax for this command is rmdir directory name
This example deletes the directory called test in the slot0 directory.
This example deletes the directory called test at the current directory level.
If the current directory is slot0:mydir, this command deletes the slot0:mydir/test directory.
Moving Files
The move command removes a file from the source directory and places it in the destination directory. If a file with the same name already exists in the destination directory, that file is overwritten by the moved file.
This example moves the file called samplefile from the slot0 directory to the mystorage directory.
switch# move slot0:samplefile slot0:mystorage/samplefile
This example moves a file from the current directory level.
switch# move samplefile mystorage/samplefile
If the current directory is slot0:mydir, this command moves slot0:mydir/samplefile to
slot0:mydir/mystorage/samplefile.
Copying Files
The copy command copies a file.
This example copies the file called samplefile from the slot0 directory to the mystorage directory.
switch# copy slot0:samplefile slot0:mystorage/samplefile
This example copies a file from the current directory level.
switch# copy samplefile mystorage/samplefile
If the current directory is slot0:mydir, this command copies slot0:mydir/samplefile to
slot0:mydir/mystorage/samplefile.
You can also use the copy command to upload and download files from the slot0: or bootflash: file
system to or from a FTP, TFTP, SFTP, or SCP server (see the "Copying Files" section).
Displaying File Contents
The show file command displays the contents of a specified file in the file system.
The syntax for this command is show file file name
This example displays the contents of the test file that resides in the slot0 directory.
switch# show file slot0:test
This example displays the contents of a file residing in the current directory.
switch# show file myfile
Displaying Disk Usage
The show flash command displays the disk usage of various devices.

Executing Commands Specified in a Script
The run-script command executes the commands specified in a file.
Note You cannot create the script files at the switch prompt. You can create the script file on an external machine and copy it the bootflash: directory. This section assumes that the scrip file resides in the bootflash: directory.
The syntax for this command is run-script file name
This example executes the CLI commands specified in the testfile that resides in the slot0 directory.
switch# show file slot0:testfile
This file output is in response to the run-script command:
switch# run-script slot0:testfile
Enter configuration commands, one per line. End with CNTL/Z.

To use this command, be sure to create the file and specify commands in the required order.
Setting the Delay Time
The sleep command delays an action by a specified number of seconds.
The syntax for this command is sleep <seconds>
You will see the switch prompt return after 30 seconds.
This command is useful within scripts. For example, if you create a script called lashtest-script:
switch# show file slot0:test-script
discover scsi-target remote
switch# run-script slot0:test-script
When you execute the slot0:test-script, the switch software executes the discover scsi-target remote command, and then waits for 10 seconds before executing the show scsi-target disk command.
Displaying the Last Line in a File
The tail command displays the last lines (tail end) of a specified file.
The syntax for this command is tail <file name> [<number of lines>]
You see the last 10 lines of the mylog file.
If you specify a long file and would like to exit in the middle, enter Ctrl-c to exit this command.
Setting the Switch's Shell Timeout
Use the exec-timeout command in configuration mode to configure the lifetime of a single terminal session. When the time limit configured by this command is exceeded, the shell exits and closes that session.
The syntax for this command from is exec-timeout minutes
The default is 30 minutes. You can configure different timeout values for a console or a virtual terminal line (VTY) session.
•From the console:
switch(config)# line console
switch(config-console)# exec-timeout 60
Specifies the current console shell timeout to be 60 minutes.
•From a VTY session (Telnet or SSH):
switch(config-line)# exec-timeout 60
Specifies the current console shell timeout to be 60 minutes.
Setting the Switch's Terminal Type
Use the terminal terminal-type command in EXEC mode to specify the terminal type for a switch:
The syntax for this command is terminal terminal-type terminal-type
switch# terminal terminal-type vt100
Specifies the terminal type (for example vt100 or xterm). Any string is accepted for the terminal-type argument. If a Telnet or SSH session specifies an unknown terminal type, the switch uses the vt100 terminal by default.
Setting the Switch's Terminal Length
To set the terminal screen length for the current session, use the terminal length command in EXEC mode:
The syntax for this command is terminal length lines
switch# terminal length 20
Sets the screen length for the current session to 20 lines for the current terminal session. The default is 24 lines.
This command is specific to only the console port. Telnet and SSH sessions set the length automatically.
Setting the Switch's Terminal Width
To set the terminal screen width for the current session, use the terminal width command in EXEC mode:
The syntax for this command is terminal width columns
switch# terminal width 86
Sets the screen length for the current session to 86 columns for the current terminal session. The default is 80 columns.
This command is specific to only the console port. Telnet and SSH sessions set the width automatically.
Displaying Terminal Settings
The show terminal command displays the terminal settings for the current session:
Length: 24 lines, Width: 80 columns
Session Timeout: 525600 minutes
Saving Command Output to a File
You can force all screen output to go to a file by appending > filename to any command. For example, enter show interface > samplefile at the EXEC mode switch prompt to save the interface configuration to samplefile—a file created at the same directory level. At the EXEC mode switch prompt, issue a dir command to view all files in this directory, including the recently saved samplefile.See "Initial Configuration," for information on saving and copying configuration files, and "Software Images," for information on saving and copying software images.
Note Redirection is allowed only if the current directory is on the volatile: (default) or slot0: file systems. Redirection is not allowed if the current directory is on the bootflash: file system. The current directory can be viewed using the pwd command and changed using the cd command.
Sending Messages to Users
The send command sends a message to all active CLI users currently using the switch. This message is restricted to 80 alphanumeric characters with spaces.
This example sends a warning message to all active users about the switch being shut down.
switch# send Shutting down the system in 2 minutes. Please log off.
Broadcast Message from admin@excal-112
(/dev/pts/3) at 16:50 ...
Shutting down the system in 2 minutes. Please log off.
Using ping
The ping command verifies the connectivity of a remote host or server by sending echo messages.
The syntax for this command is ping <host or ip address>
switch# ping 198.133.219.25
PING 198.133.219.25 (198.133.219.25) 56(84) bytes of data.

2 packets transmitted, 2 received, 0% packet loss, time 999ms
rtt min/avg/max/mdev = 0.856/0.941/1.027/0.090 ms
To abnormally terminate a ping session, type the Ctrl-C escape sequence
Using traceroute
The traceroute command prints the routes taken by a specified host or IP address.
The syntax for this command is traceroute <host or ip address>
switch# traceroute www.cisco.com

Saving a Configuration
To save the configuration, enter the copy running-config startup-config command from the EXEC mode prompt to save the new configuration into nonvolatile storage. Once this command is issued, the running and the startup copies of the configuration are identical.
See the "Copying Files" section.
Clearing a Configuration
To completely clear a configuration, enter the write erase command from the EXEC mode prompt. Once this command is issued, the existing configuration is cleared and the switch reverts to factory defaults.
Role-Based CLI
By default, two roles exist in all switches:
•Network operator—Has permission to view the configuration.
•Network administrator—Has permission to execute all commands and to set up to 64 permission levels based on user roles and groups (see "Configuring System Security and AAA Services").
When you execute a command, perform command completion, or obtain context sensitive help, the switch software allows the operation to progress if you have the correct permission as specified in the description of the command.
Using Valid Formats and Ranges
