| statements: | TRLE |
| dependency: | OSA port operating in either ATM native mode or in QDIO mode. Specify a link_num value only for an OSA-Express port that is operating in QDIO mode and customized for LAN emulation. The link_num value is mutually exclusive with the PORTNUM operand of the TRLE definition statement. |
- port_name
- Specifies the Open Systems Adapter (OSA) port name. The name must
be unique in one logical partition and it must be unique for an OSA
CHPID that is shared by multiple logical partitions. Some OSA-Express3
or later features provide support for multiple ports per CHPID. The
port name assigned to each port on a specific CHPID must also be unique.
In general, each defined port name should be unique within your network.
The maximum length for the port_name value
is 8 characters.
For an OSA port customized for HPDT ATM native mode, the port_name value must match the port name specified when OSA is customized through OSA/SF. If this name is used by TCP/IP, it must also be defined as the port name in the TCP/IP profile DEVICE statement. If this name is used for SNA HPR over native ATM connections, it must also be defined as the port name in the PORT statement in a VTAM® XCA major node.
For an Open Systems Adapter-Express (OSA-Express) port operating in QDIO mode, the name specified for the port_name value is downloaded into the OSA-Express when the first TCP/IP device for this OSA-Express port is activated. For OSA-Express QDIO connections, this name must be defined as the device name in the TCP/IP profile DEVICE statement or as the port name in the TCP/IP profile INTERFACE statement for any TCP/IP stack that will use this OSA-Express feature. This name must also be defined as the port name on a VARY TCPIP,,OSAENTA command or the port name on an OSAENTA profile statement if a TCP/IP stack will start an OSA-Express network traffic analyzer trace on this OSA feature.
- link_num
- Specifies the ATM LAN emulation client (LEC) port number 0 or 1 for an OSA-Express port operating in QDIO mode customized for LAN emulation. The default is 0. For each OSA ATM port in QDIO mode, two LAN Emulation Clients (LEC) can be customized through OSA/SF. Each LEC represents one logical OSA port, and therefore each must be represented by a different TRLE with unique PORTNAME and unique LEC port number. If two LECs are customized, both LECs must operate in QDIO mode.
