Cisco IOS XE
Operating system for network equipment
IOS XE is a release train of Cisco Systems' widely deployed Internetworking Operating System (IOS), introduced with the ASR 1000 series.[2]
It is built on Linux[3][4] and provides a distributed software architecture that moves many operating system responsibilities out of the IOS process[5][6] and has a copy of IOS running as a separate process.[7] Since it runs a copy of IOS, all CLI commands are the same between Cisco IOS and IOS XE, in contrast to IOS XR, which has a completely different code base and whose developers implemented a different CLI command set.
