Enabling Software Features on Devices
Using a Command Option
The capability to activate software applications or components on a device using a command is supported on
this platform.
Starting with Release 9.4(0.0), you can enable or disable specific software features or applications that need
to run on a device by using a command attribute in the CLI interface. This enables effective, streamlined
management and administration of applications and utilities that run on a device. You can employ this
capability to perform an on-demand activation, or turn-off a software component or protocol. A feature
configuration file generated for each image contains feature names, and denotes if this enabling or disabling
method is available. You can enable or disable the VRF application globally across the system by using this
capability.
Activate the VRF application on a device by using the feature vrf command in CONFIGURATION mode.
NOTE: The no feature vrf command is not supported on any of the platforms.
To enable the VRF feature and cause all VRF-related commands to be available or viewable in the CLI
interface, use the following command. You must enable the VRF feature before you can configure its related
attributes.
Dell(conf)# feature vrf
Based on if the VRF feature is identified as supported in the Feature Configuration file, configuration
command feature vrf becomes available for usage. This command is stored in the running-configuration
and precedes all other VRF-related configurations.
To display the state of Dell Networking OS features:
Dell# show feature
Example of show feature output
For a particular target where VRF is enabled, the show output is similar to the following:
