boot
When the 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 SSM 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
