Enabling Software Features on Devices Using a Command Option
This capability to activate software applications or components on a device using a command is supported on the S4810, S4820T,
and S6000, platforms.
Starting with Release 9.4(0.0), you can enable or disable specic software functionalities or applications that need to run on a device
by using a command attribute in the CLI interface. This capability enables eective, 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-o of a
software component or protocol. A feature conguration le that is generated for each image contains feature names denotes
whether this enabling or disabling method is available for such features. In 9.4(0.0), you can enable or disable the VRF application
globally across the system by using this capability.
You can activate 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 congure its related attributes.
Dell(conf)# feature vrf
Based on whether VRF feature is identied as supported in the Feature Conguration le, conguration command feature vrf
becomes available for usage. This command will be stored in running-conguration and will precede all other VRF-related
congurations.
NOTE: The MXL and Z9000 platforms currently do not support VRF. These platforms support only the management and
default VRFs, which are available by default. As a result, the feature vrf command is not available for these platforms.
To display the state of Dell Networking OS features:
