The Bundle mode uses monolithic Cisco IOS images to boot a switch. The Install mode uses a package-provisioning file named nf in order to boot a switch. IOS XE has two modes of operation, Install and Bundle. While Cisco IOS is a monolithic operating system running directly on the hardware, the IOS XE series is a combination of a linux kernel and a (monolithic) application (IOSd) that runs on top of this kernel.

Modular: Modular software independently upgrades individual software modules.

Secure: End-to-end security and trust are built in.

Programmable: Programmable interface enables process and orkflow automation.Open: Standards-based capabilities on Cisco network devices accelerate business and network innovation.In the last years, Cisco introduced a new type of IOS: IOS XE. Then if all tests were ok, it started the unpacking of the tar file on all switches (in case of a stack) and changed the bootvar. The archive download algorithm checked that the image was appropriate for the switch model, that enough DRAM was present and that md5 was correct. bin file), change the bootvar and reload the switch then Cisco introduced the tar file using the “ archive download-sw” command. In the past, upgrade a switch was very easy: upload the IOS file (a.
