Alias for a Flash file system. Use flash: for the system board Flash device. Optional Path directory and name of a bootable image.
Separate the image names with a semicolon. The switch attempts to automatically boot the system by 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. When you enter the boot command without any arguments, the switch attempts to automatically boot the system by using the information in the BOOT environment variable, if any.
If you supply an image name for the file-url variable, the boot command attempts to boot the specified image. When you set boot loader boot command options, they are executed immediately and apply only to the current boot loader session. These settings are not saved for the next boot operation. Filenames and directory names are case sensitive.
This example shows how to boot the switch using the new-image. After entering this command, you are prompted to start the setup program. Use the cat boot loader command to display the contents of one or more files. Path directory and name of the files to display. Separate each filename with a space. If you specify a list of files, the contents of each file are sequentially displayed.
This example shows how to display the contents of config. Use the copy boot loader command to copy a file from a source to a destination. Filenames are limited to 45 characters; the name cannot contain control characters, spaces, deletes, slashes, quotes, semicolons, or colons.
If you are copying a file to a new directory, the directory must already exist. This example show how to copy a file at the root:. You can verify that the file was copied by entering the dir filesystem: boot loader command. Use the delete boot loader command to delete one or more files from the specified file system.
The switch prompts you for confirmation before deleting each file. This example shows how to delete two files:. You can verify that the files were deleted by entering the dir flash: boot loader command. Use the dir boot loader command to display a list of files and directories on the specified file system. Optional Path directory and directory name whose contents you want to display. Separate each directory name with a space. This example shows how to display the files in Flash memory:.
Table B-1 describes the fields in the display. This command has no arguments or keywords. The Flash file system is automatically initialized during normal system operation. During the normal boot process, the Flash file system is automatically initialized. Use this command to manually initialize the Flash file system. For example, you use this command during the recovery procedure for a lost or forgotten password. Use the format boot loader command to format the specified file system and destroy all data in that file system.
Use the fsck boot loader command to check the file system for consistency. An extensive, nondestructive memory test is performed on every byte that makes up the file system. Optional Initialize the file system code and perform a fast file consistency check.
Cyclic redundancy checks CRCs in the flashfs sectors are not checked. To stop an in-progress file system consistency check, disconnect the switch power and then reconnect the power. This example shows how to perform an extensive file system check on Flash memory:. Use the help boot loader command to display the available commands. You can also use the question mark?
Path directory and a list of loadable helper files to dynamically load during loader initialization. Separate each image name with a semicolon. Refer to the device manager online help for more information. For more advanced configuration, download and run the Cisco Network Assistant described in the next section. Network Assistant offers advanced options for configuring and monitoring multiple devices, including switches, switch clusters, switch stacks, routers, and access points.
Page 9: Rack Mounting This section covers basic inch rack-mounting and switch port connections. As an example, all the illustrations show the Catalyst GEI switch. You can install and connect other Catalyst switches as shown in these illustrations. For alternate mounting procedures, such as installing the switch in a inch rack or on a wall, and for additional cabling information, refer to the Catalyst Switch Hardware Installation Guide on Cisco.
