Enabling and Disabling Features
Introduced: Cisco NX-OS Release 4.0(1)
Cisco NX-OS software has the ability to enable and disable specific features, such as OSPF and PIM. By default, Cisco NX-OS software enables only those features that are required for initial networking connectivity. This approach optimizes the operating system and increases availability by not running additional processes that are not required.
If a feature is not enabled, the process for that feature is not running, and the configuration and verification (show) commands are not available from the CLI. Once a feature is enabled, the configuration and verification commands can be executed. Depending on the feature, the process will not start until the feature is configured (such as router ospf 10). We recommend that you keep the features disabled, or disable them if they are no longer required.
