Cisco ASR 1000 Series Routers
Entering show version without any of the options on the Cisco ASR 1000 Series Router will generate
output similar to show version on other Cisco routers.
In order to understand the show version output on Cisco ASR 1000 Series Routers, it is important to
understand that the individual sub-packages run the processes on the router. Among other things, the
output of this command provides information on where various individual sub-packages are stored on
the router, and which processes these individual sub-packages are and are not currently running.
More specifically, the show version installed command displays each individual sub-package file on the
router, the hardware where the sub-package could be running, and whether the sub-package is currently
being run on that hardware.
The show version provisioned command displays only the individual sub-packages that can be
provisioned, which are the RP-specific sub-packages (RP Access, RP Base, RP Control, and RP IOS)
and the provisioning file. The output includes the individual sub-package file, the hardware where the
sub-package could be running, and whether the sub-package is currently being run on that hardware.
The show version running command displays only the individual sub-packages that are currently active.
The output includes the individual sub-package file and the hardware where the sub-package is running.
