Automatically Saving the Running Configuration
Cisco MDS NX-OS provides an option to automatically save any configuration changes to the startup
configuration. This ensures that the new configuration is present after a switch reboot. By default, the
Active=Saved active equals saved option is automatically enabled on any FICON VSAN.
Table 23: Saving the Active FICON and Switch Configuration , on page 268 displays the results of the Active
= Saved option active equals saved command and the implicit copy from the running configuration to the
startup configuration (copy running start)copy running-config startup-config command in various scenarios.
When the Active=Saved option active equals saved command is enabled in any FICON-enabled VSAN in
the fabric, then the following apply (see Number 1 and 2 in Table 23: Saving the Active FICON and Switch
Configuration , on page 268):
• All configuration changes (FICON-specific or not) are automatically saved to persistent storage (implicit
copy running start) and stored in the startup configuration.
• FICON-specific configuration changes are immediately saved to the IPL file (see the FICON Configuration
Files, on page 279).
If the Active=Saved option active equals saved command is not enabled in any FICON-enabled VSAN in
the fabric, then FICON-specific configuration changes are not saved in the IPL file and an implicit copy
running startup command is not issued, you must explicitly save the running configuration to the startup
configurationissue the copy running start command explicitly (see number 3 in Table 23: Saving the Active
FICON and Switch Configuration , on page 268).
