application 
Use this command to select the application ID to be configured for this QSFP-DD module. 
Use the no parameter with this command to remove this configuration. If no application is configured then application ID 1 will be selected as per module default.
Note:	Only 400G application modes are supported.
Note:	For checking the supported applications modes show qsfp-dd <port no.> advertisement applications command, see the example.
Example:
OcNOS#show qsfp-dd 49 application
