Save NVRAM as Separate File in GNS3


While saving configurations in NVRAM of any Cisco device, say router or switch, in physical devices, the things are prearranged are easily done as everything is real and tangible. However when talking about GNS3, just like all other virtualization applications, all the hardware which virtual devices consider as physical devices are actually the files for physical computers. Same is the case with NVRAM of any virtual Cisco device used in GNS3. This means that NVRAM which GNS3 virtual devices considered as the physical ones are the files to the physical computers and therefore can be saved separately. These files can then be imported to any other virtual device as required. You can allow GNS3 to save NVRAM of virtual Cisco devices as separate files by following the steps given below. This configuration should be done when GNS3 application is started and/or when user wishes to create a new project.
