Saving or Upgrading a Configuration
The configuration files control the operation of the switch, and contain the
functional settings at the device and the port level. Configuration files are one of
the following types:
• Factory Default — Contains preset default parameter definitions which are
downloaded with a new or upgraded version.
• Running Configuration — Contains the parameter definitions currently
defined on the device. This includes any configuration changes made since
the device was started or rebooted. When the device shuts down or
reboots the next time, this configuration becomes the Startup
Configuration.
• Startup configuration — Contains the parameter definitions which were
valid in the Running Configuration when the system last rebooted or shut
down.
• Backup configuration — Contains a copy of the system configuration for
protection against system shutdown, or for maintenance of a specific
operating state.
