SmartWare Software Configuration Guide
5 • System image handling
Operating configurations cannot be executed from the persistent memory, so the configuration used for oper-
ating the SmartNode is copied into the volatile memory of the SmartNode prior to normal operation. This
procedure takes place after the system bootstrap, where the application image (i.e. SmartWare) is started and a
configuration must be available. Shortly before SmartWare has completed all startup processes, the configura-
tion
startup-config
is copied from
nvram:
in persistent memory to the
running-config
configuration in system: in
volatile memory.
You can back up the
running-config
to
nvram:
or to a remote TFTP server with a user-defined name.
Note
When returning to the
factory-config
by using the
copy factory-config star-
tup-config
command, all user-specific configurations saved in
nvram:
remain even after
reload
.
