nvData
When you work with nvData, you can:
■
Restore the module’s nvData values to their factory defaults, using the
reset
option. Use the
reset
option if you have problems with a new
setting and want to start over again.
■
Prepare the system (update the image name and IP address) for an
emergency download using the
emergencyDownload
option.
■
Display the last download performed on the module you selected
using the
displayDownload
option.
■
Save the nvData settings when you hot-swap a module, using the
staging
option. The nvData settings are saved when you set the
staging
bit on a module to
enable
and hot-swap that module to
another Switch 4007 chassis.
If you hot-swap a module with the
staging
option set to
disable
to a
Switch 4007 chassis slot where the same type of module was previously
installed, the module learns the previous module’s settings from the EME
module. Otherwise, the module is reset to its factory default settings.
