NSO Packages contain data models and code for a specific function. It might be a NED for a specific device, a service application like MPLS VPN, a WebUI customization package etc. Packages can be added, removed and upgraded in run-time.
The currently loaded packages can be viewed with the following command:
admin@ncs# show packages
packages package cisco-ios
package-version 3.0
description "NED package for Cisco IOS"
ncs-min-version [ 3.0.2 ]
directory ./state/packages-in-use/1/cisco-ios
component upgrade-ned-id
upgrade java-class-name com.tailf.packages.ned.ios.UpgradeNedId
component cisco-ios
ned cli ned-id cisco-ios
ned cli java-class-name com.tailf.packages.ned.ios.IOSNedCli

Thus the above command shows that NSO currently has only one
package loaded, the NED package for Cisco IOS. The output includes
the name and version of the package, the minimum required NSO
version, the Java components included, package build details, and
finally the operational status of the package. The operational
status is of particular importance - if it is anything other than
up, it indicates that there was a problem with
the loading or the initialization of the package. In this case an
item error-info may also be present, giving additional
information about the problem. To show only the operational status
for all loaded packages, this command can be used:
admin@ncs# show packages package * oper-status
packages package cisco-ios
oper-status up
