Configuration file Description
Running configuration
• running-config
Current configuration active on the switch. Whenever you make a
configuration change, it is written to the running configuration. For
fabric cluster mode, the running configuration does not persist
across reboot, unless you copy it to the startup configuration.
However, when the switch is in logical chassis cluster mode, the
running-config file is saved automatically and it does not need to be
copied.
Configuration management follows a transaction model. When you boot up a switch for the first time,
the running configuration is identical to the startup configuration. As you configure the switch, the
changes are written to the running configuration. To save the changes, you must save the currently
effective configuration (the running configuration) as the startup configuration. When the switch
reboots, the configuration changes become effective.
Default configuration
Network OS provides two different configuration files for switches in standalone and Brocade VCS
Fabric mode. When you change from standalone to Brocade VCS Fabric mode, the system chooses
the appropriate default configuration based on the mode (Brocade VCS Fabric or standalone). Default
configuration files are part of the Network OS firmware package and are automatically applied to the
startup configuration under the following conditions:
• When the switch boots up for the first time and no customized configuration is available.
• When you enable or disable Brocade VCS Fabric mode, the appropriate default configuration is
applied when the switch reboots.
• When you restore the default configuration.
You cannot remove, rename, or change the default configuration.
Startup configuration
NOTE
There is no startup configuration for logical chassis cluster mode. Switches in a logical chassis cluster
always preserve their running configuration.
The startup configuration is persistent. It is applied when the system reboots.
• When the switch boots up for the first time, the switch uses the default configuration as the startup
configuration, depending on the mode.
• The startup configuration always matches the current Brocade VCS Fabric mode. It is deleted when
you change modes, unless you make a backup copy.
• When you make configuration changes to the running configuration and save the changes to the
startup configuration with the copy command, the running configuration becomes the startup
configuration.
Running configuration
The configuration currently effective on the switch is referred to as the running configuration. Any
configuration change you make while the switch is online is made to the running configuration.
