[OFOS] help add vnic Add a new virtual Network Interface Card (vNIC) to the system. You must provide a hierarchical name for the vNIC at the time that it is added. A 'hierarchical' name includes the name of the vNIC, plus the name of the server profile to which A second (optional) parameter of the 'add' command specifies the termination for the vNIC. A vNIC can be terminated on an I/O port. For example, when you type: add vnic vNIC_name.server_profile_name slot/port, the vNIC is assigned. The two names are separated by the dot '.' character. For example: add vnic vNIC_name.server_profile_name.
