You can view the vNIc configuration of each service profile by scoping into service profile and executing " show vnic detail " command
UCS # scope service-profile org
UCS /org/service-profile # show vnic detail
Can you please clarify your end requirement ?
You can use classId="vnicEther" in XML query to get all the vNICs configured in UCS service profiles.
