6.1.4.3. Non-Disruptive Configuration Management
The Non-Disruptive Configuration feature can apply a new configuration file without disrupting the
operation of features that are unchanged by the new configuration.
In the datacenter network, where the network administrator may manage thousands of switches, when the
switch configuration is changed by uploading a new configuration file to it, the switch can gracefully resolve
any differences between the running configuration and the new configuration. For example, if the switch has
VLANs
10, 20, and 30 configured, and the new configuration has VLANs 10, 20, and 40, the switch deletes VLAN 30
and creates VLAN 40 without disturbing traffic forwarding on VLANs 10 and 20.
Without this feature, to upgrade to a new configuration, the administrator must either provide a new
configuration file and restart the switch or upload a ‘delta’ configuration. Restarting the switch is disruptive,
and managing delta configurations is difficult on a large scale.
The following commands can be used to apply the configuration gracefully.
 reload configuration — Applies the startup-config gracefully.
 reload configuration <scriptfile> — Applies the given script file gracefully.
6.1.5. Saving the Running Configuration
Changes you make to the switch configuration while the switch is operating are written to the running-
config. These changes are not automatically written to the startup-config. When you reload the switch, the
startup- config file is loaded. If you reload the switch (or if the switch resets unexpectedly), any settings in
the running- config that were not explicitly saved to the startup-config are lost. You must save the running-
config to the startup-config to ensure that the settings you configure on the switch are saved across a switch
reset.
To save the running-config to the startup-config from the CLI, use the copy running-config startup-config
command.
