You can enable and disable a specific DCB feature after DCB has been globally enabled. For example, when exchanging a DCBX protocol with its peer, you might want to inform its peer that a DCB-specific feature has been enabled or disabled.
The following example enables the PFC feature and disables PG and the application. This example uses port 0/2.
