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 specic software features or applications that need to run on a device by using a

command attribute in the CLI interface. This 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 a software component or protocol. A

feature conguration le 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 congure its related attributes.

DellEMC(conf)# feature vrf

Based on if the VRF feature is identied as supported in the Feature Conguration le, conguration command feature vrf becomes

available for usage. This command is stored in the running-conguration and precedes all other VRF-related congurations.

To display the state of Dell EMC Networking OS features:

DellEMC# show feature

Example of show feature output

For a particular target where VRF is enabled, the show output is similar to the following:

Feature State

------------------------

VRF Enabled

View Command History

The command-history trace feature captures all commands entered by all users of the system with a time stamp and writes these

messages to a dedicated trace log buer.

The system generates a trace message for each executed command. No password information is saved to the le.

NOTE

The timestamps display format of the show command history output changes based on the service timestamps log

datetime conguration. The time format can be in uptime, local time zone time or UTC time.

If timestamp is disabled (no service timestamps log) then command history time format is shown with timestamp defaults

(service timestamps log datetime localtime).

To view the command-history trace, use the show command-history command.
