Chapter 4 Before You Begin
Switch Roles
Internal bootflash:
All switches in the Cisco MDS 9000 Family have one internal bootflash: that resides in the supervisor
or switching module.You have access to two directories within the internal bootflash: file system.
•
The volatile: directory which provides temporary storage, and is also the default. Files in temporary
storage (volatile:) are erased when the switch reboots.
• The bootflash (nonvolatile storage): directory which provides permanent storage. The files in
bootflash are preserved through reboots and power outages.
External CompactFlash (Slot0)
Cisco MDS 9500 Series directors contain an additional external CompactFlash called slot0:
The external CompactFlash, an optional device for MDS 9500 Series directors, can be used for storing
software images, logs, and core dumps.
Switch Roles
By default, two roles exist in all switches:
•
Network operator—Has permission to view the configuration.
• Network administrator—Has permission to execute all commands and to set up to 64 permission
levels based on user roles and groups.
When you execute a command, perform command completion, or obtain context sensitive help, the
switch software allows the operation to progress if you have the correct permission as specified in the
description of the command.
