Chapter 3 Assigning the Switch IP Address and Default Gateway

Modifying the Startup Configuration

 

Command

Purpose

Step 4

 

 

show boot

Verify 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-urlboot 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.

Step 5

 

 

copy running-config startup-config

(Optional) Save your entries in the configuration file.

 

 

 

To disable manual booting, use the no boot manual global configuration command.

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.

Beginning in privileged EXEC mode, follow these steps to configure the switch to boot up a specific image during the next boot cycle:

 

Command

Purpose

Step 1

 

 

configure terminal

Enter global configuration mode.

Step 2

 

 

boot system filesystem:/file-url

Configure the switch to boot up 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.

 

 

If you enter this command on a Catalyst 3750-E stack master, the specified

 

 

software image is loaded only on the stack master during the next boot

 

 

cycle.

 

 

Filenames and directory names are case sensitive.
