Core issue

This message is displayed, when the copy start tftp command is issued to backup the configuration files.


In some cases, when the show startup-config command is issued, the %% Non-volatile configuration memory is not present was outputed error message is observed.

Resolution

The workaround is to issue a write memory command before you back up the configuration, in order to make sure the configuration is saved in non-volatile RAM (NVRAM).
