Some OSA-Express3 or later features provide support for
multiple ports per network interface card (NIC). To access these ports,
you must supply a physical port number on the QDIO TRLE definition
to distinguish between the physical ports on an OSA-Express3 or later
NIC. For additional information, see zEnterprise System and System z10 OSA-Express
Customer's Guide and Reference.
- port_num
- Specifies the physical port number of an OSA-Express3 or later NIC that is to be associated with this QDIO MPC group. The PORTNAME and PORTNUM values together uniquely define the OSA-Express3 or later physical port. The value of the PORTNUM operand is zero-based; the value port_num 0 represents the first physical port, port_num 1 represents the second port, up to port_num 15, which represents the sixteenth physical port. The default is 0.
Rule: Although the PORTNUM operand supports up to the value 15 (that is, 16 physical ports), do not code a value higher than what the OSA-Express3 or later NIC supports. If the port_num value is higher than the physical capabilities of the OSA-Express3 or later NIC, failures will occur when QDIO is activated.
