send
To send a message to all active CLI users currently using the switch, use the send command in EXEC mode.
send message-text
Syntax Description
message-text
|
The text of your message.
|
Defaults
None.
Command Modes
EXEC mode.
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.0(2).
Usage Guidelines
This message is restricted to 80 alphanumeric characters with spaces.
Examples
The following 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.
setup
To enter the switch setup mode, use the setup command in EXEC mode.
setup
Syntax Description
This command has no arguments or keywords.
Defaults
None.
Command Modes
EXEC mode.
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.0(2).
Usage Guidelines
Refer to the Cisco MDS 9000 Family Configuration Guide for more information on using the setup command.
The setup utility guides you through the basic configuration process. Type Ctrl-c at any prompt to skip the remaining configuration options and proceed with what is configured until that point.
If you do not wish to answer a previously-configured question, or if you wish to skip answers to any questions press Enter. If a default answer is not available (for example switch name), the switch uses what is previously configured and skips to the next question.
Examples
The following example shows how to enter switch setup mode.
---- Basic System Configuration Dialog ----
This setup utility will guide you through the basic configuration of
the system. Setup configures only enough connectivity for management
*Note: setup always assumes a predefined defaults irrespective
of the current system configuration when invoked from CLI.
Press Enter incase you want to skip any dialog. Use ctrl-c at anytime
to skip away remaining dialogs.
Would you like to enter the basic configuration dialog (yes/no): yes
sleep
To delay an action by a specified number of seconds, use the sleep command.
sleep <seconds>
Syntax Description
<seconds>
|
The number of seconds to delay an action.
|
Defaults
None.
Command Modes
EXEC mode.
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.0(2).
Usage Guidelines
This command is useful within scripts. For example, if you create a script called test-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.
Examples
The following example shows how to delay the switch prompt return.
You will see the switch prompt return after 30 seconds.
snmp-server

Command Modes
Configuration mode
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.0(2).
Usage Guidelines
The localized keys are not portable across devices as they contain information on the engine ID of the device. If a configuration file is copied into the device, the passwords may not be set correctly if the configuration file was generated at a different device. We recommend that passwords be explicitly configured to the desired passwords after copying the configuration into the device.
Examples
The following example sets the contact information, switch location, and switch name.
switch(config)# snmp-server contact NewUser
switch(config)# no snmp-server contact NewUser
switch(config)# snmp-server location SanJose
switch(config)# no snmp-server location SanJose
switch(config)# snmp-server name NewName
switch(config)# no snmp-server name NewName

Use these frames to identify the FCIP link endpoints, to learn about the critical parameters shared by Fibre Channel and FCIP profile pairs involved in the FCIP link, and to perform configuration discovery
Examples
switch(config)# interface fcip 1
switch(config)# peer-info ipaddr 10.1.1.1

Usage Guidelines
Perform a switchover when the switch has two supervisor modules functioning in the switch. The system switchover command returns a Failed to switchover: (supervisor has no standby) message when the standby supervisor is not present in the switch.
Any switchover function is nonrevertive. Once a switchover has occurred and the failed processor has been replaced or successfully restarted, you cannot switch back to the original, active supervisor module (unless there is a subsequent failure or you issue the system switchover command).
Examples
The following example initiates a HA switchover from an active supervisor module to a standby supervisor module.
