Performing Switch Setup Configuration
How to Perform Switch Setup Configuration
Booting a Specific Software Image
By default, the switch attempts to automatically boot up the system using information in the BOOT environment variable.
If this variable is not set, the switch attempts to load and execute the first executable image it can by performing a
recursive, depth-first search throughout the flash file system. In a depth-first search of a directory, each encountered
subdirectory is completely searched before continuing the search in the original directory. However, you can specify a
specific image to boot up.
Command Purpose
1. configure terminal Enters global configuration mode.
2. boot manual Enables the switch to manually boot up during the next boot cycle.
3. end Returns to privileged EXEC mode.
4. show boot Verifies your entries.
The boot manual global command changes the setting of the
MANUAL_BOOT environment variable.
The next time you reboot the system, the switch is in boot loader
mode, shown by the switch: prompt. To boot up the system, use the
boot filesystem:/file-url boot loader command.
For filesystem:, use flash: for the system board flash device.
For file-url, specify the path (directory) and the name of the
bootable image.
Filenames and directory names are case sensitive.
5. copy running-config startup-config (Optional) Saves your entries in the configuration file.
Command Purpose
1. configure terminal Enters global configuration mode.
2. boot system filesystem:/file-url Configures the switch to boot a specific image in flash memory during the
next boot cycle.
For filesystem:, use flash: for the system board flash device.
For file-url, specify the path (directory) and the name of the bootable
image.
Filenames and directory names are case sensitive.
3. end Returns to privileged EXEC mode.
4. show boot Verifies your entries.
The boot system global command changes the setting of the BOOT
environment variable.
During the next boot cycle, the switch attempts to automatically boot up
the system using information in the BOOT environment variable.
5. copy running-config startup-config (Optional) Saves your entries in the configuration file.
