Information About Device File Systems, Directories, Files, and External Storage Devices
This section describes the file systems, directories, files, and support provided to the external storage devices on devices.
File Systems
This topic provides information about the file system components supported on a Cisco MDS device. (The syntax for specifying a local file system is filesystem:[//modules/] . )
Note |
The default filesystem parameter is bootflash:. |
This table describes the file system components that you can use on a Cisco MDS device.
File System Name |

bootflash |
sup-active sup-local |
Internal CompactFlash memory located on an active supervisor module. Used for storing image files, configuration files, and other miscellaneous files. The initial default directory is bootflash. |
sup-standby sup-remote |
Internal CompactFlash memory located on a standby supervisor module. Used for storing image files, configuration files, and other miscellaneous files. |
|
volatile |
— |
Volatile random-access memory (VRAM) located on a supervisor module. Used for temporary or pending changes. |
log |
— |

system |
— |
Memory on a supervisor module. Used for storing the running configuration file. |
debug |
— |
Memory on a supervisor module. Used for storing the debug logs. |
Directories
You can create directories on bootflash: and external flash memory (slot0:, usb1:, and usb2:). You can create, store, and access files from directories.
Files
You can create and access files from bootflash:, volatile:, slot0:, usb1:, and usb2: file systems. You can only access files from the system: file system. Use the debug: file system to store the debug log files specified using the debug logfile command.
You can download files, such as system image files, from remote servers using FTP, Secure Copy Protocol (SCP), Secure File Transfer Protocol (SFTP), and TFTP. You can also copy files from an external server to your device because your device can act as an SCP server.
