banner motd

To configure a message of the day (MOTD) banner, use the banner motd command in configuration mode.

banner motd [delimiting-character message delimiting-character]

no banner motd [delimiting-character message delimiting-character]

Syntax Description

delimiting-character	Identifies the delimiting character.
message	Specifies the banner message that is restricted to 40 lines with a maximum of 80 characters in each line.

Defaults

None.

Command Modes

Configuration mode.

Command History

This command was introduced in Cisco MDS SAN-OS Release 1.3(4).

Usage Guidelines

The configured MOTD banner is displayed before the login prompt on the terminal whenever a user logs in to a Cisco MDS 9000 Family switch.

Follow these guidelines when choosing your delimiting character:

•Do not use the delimiting-character in the message string.

•Do not use " and % as delimiters.

You can include tokens in the form $(token) in the message text. Tokens will be replaced with the corresponding configuration variable. For example:

•$(hostname) displays the host name for the switch

•$(line) displays the vty or tty line no or name

•The $(line-desc) and $(domain) tokens are not supported.

Examples

The following example configures a banner message with the following text "Testing the MOTD Feature."

switch# config t

switch(config)# banner motd # Testing the MOTD Feature. # 

The following example spans multiple lines and uses tokens to configure the banner message:

switch# config t

switch(config)# banner motd # 
Enter TEXT message. End with the character '#'. 
Welcome to switch $(hostname). 
You tty line is $(line). 
#

boot

To perform operations on the system, use the boot command in configuration mode. Use the no form of this command to negate this feature or return to factory defaults.

boot {asm-sfn {bootflash: | slot0: | tftp:}[image] [ module [slot-number]] |
auto-copy |
kickstart {bootflash: | slot0: | tftp:}[image] [sup-1 [sup-2] | sup-2] |
lasilc {bootflash: | slot0: | tftp:}[image] [ module [slot-number]] |
system {bootflash: | slot0: | tftp:}[image] [sup-1 [sup-2] | sup-2]}

no boot {asm-sfn | auto-copy | kickstart | lasilc | system}

Syntax Description

asm-sfn	Configures the virtualization image.
module slot-number	Specifies the slot number of the ASM.
auto-copy	Configures auto-copying of boot variable images.
kickstart	Configures the kickstart image.
lasilc	Configures the boot image.
system	Configures the system image.
bootflash:	Specifies system image URI for bootflash.
slot0:	Specifies system image URI for slot 0.
tftp:	Specifies system image URI for TFTP.
image	Specifies the image file name.
sup-1	The upper supervisor.
sup-2	The lower supervisor.

Defaults

Disabled.

Command Modes

Configuration mode.

Command History

This command was modified in Cisco MDS SAN-OS Release 1.2(2).

Usage Guidelines

The boot kickstart slot0:image command is currently not allowed. For kickstart, only bootflash: is allowed.

Whenthe boot auto-copy command is issued, the system copies the boot variable images which are local (present) in the active supervisor module (but not in the standby supervisor module) to the standby supervisor module. For kickstart and system boot variables, only those images that are set for the standby supervisor module are copied. For modules (line card) images, all modules present in standby's corresponding locations (bootflash: or slot0:) will be copied.

Examples

The following example adds the new system image file to the SYSTEM environment variable.

switch(config)# boot system bootflash:system.img

The following example boots from the CompactFlash device (slot0:). The switch updates the SYSTEM environment variable to reflect the new image file in the specified Flash device.

switch(config)# boot system slot0:system.img

The following example overwrites the old Kickstart environment variable in the configuration file:

switch(config)# boot kickstart bootflash:kickstart.img

The following example specifies the ASM image to be used:

switch(config)# boot asm-sfn bootflash:m9000-ek9-asm-sfn-mz.1.2.2.bin

The following example enables automatic copying of boot variables from the active supervisor module to the standby supervisor module.

switch(config)# boot auto-copy 

The following example disables the automatic copy feature (default).

switch(config)# no boot auto-copy
