This topic is to discuss the following lesson:
What is/are the file system type(s) used by Cisco IOS (for example the flash: file system)? Similar to Linux file system types - ext2, ext3, etc.
In most cases, the file system used is fat32. This can be seen from the fact that most cisco IOS platforms have the
fsck utility which is a FAT filesystem check. Also, most USB flash drives that are used as external storage ports on cisco devices are recommended to be formated as fat32.
Some cisco platforms have the ability to change file systems as well. Depending on the platform, using the IOS command
filesystem filesystem-type you are able to format any file system (flash, nvram or usb flash drive) on a Cisco device to fat16, fat32 or qnx4.
I hope this has been helpful!
