This parameter does not apply to the stand-alone 400 Multi-protocol Router. The Ethernet port used by the tunnel (ge0 or ge1). The tunnel number (0 - 7). The config option creates a configuration. Enables or disables XRC emulation. 1 is enable, O is disable. Enables or disables tape write pipelining. 1 is enable, O is disable. Enables or disables tape read pipelining. 1 is enable, O is disable. Enables or disables TIN/TIR emulation. 1 is enable, O is disable. Enables or disables device level ACK emulation. 1 is enable, O is disable. Enables or disables FICON read block ID. 1 is enable, O is disable. Defines a maximum number of channel commands that may be outstanding at a given time during write pipelining. Too small of a value will result in poor performance. The value should be chosen carefully based upon the typical tape channel program that requires optimum performance. The default value is 32. the range is 1-100. Defines a maximum number of channel commands that may be outstanding at a given time during read pipelining. Too small of a value will result in poor performance. The value should be chosen carefully based upon the typical tape channel program that requires optimum performance. The default value is 32. The range is 1-100. Defines a maximum number of concurrent emulated tape write operations. The default value is 16.The range is 1-32. Defines a maximum number of concurrent emulated tape read operations. The default value is 16. The range is 1-32. Defines a time limit for pipelined write chains. This value is be specified in milliseconds (ms). If a pipelined write chain takes longer than this value to complete, the ending status for the next write chain will be withheld from the channel. This limits processing to what the network and device can support. Too small a value limits pipelining performance. Too large a value results in too much data being accepted for one device on a path. The default value is 300 milliseconds (ms). The range is 100-1500. Defines the maximum amount of data that can be contained in a single CCW chain. If this value is exceeded, emulation is suspended. The default is 3, which represents 3000000 bytes. Defines the base value of an entry pool of 256 OXIDs supplied to emulation generated exchanges. It should fall outside the range used by FICON channels and devices to avoid conflicts. The default value is 0x1000. The range is 0x0000 to 0xF000. Defines optional debug flags. The default is 0xF7C80000. This is primarily for use by technical support personnel. The following example shows FICON emulation on ge0 over tunnel id 1 with FICON XRC and tape write pipelining enabled. The default values are assumed for wrtMaxPipe, wrtMaxDev, wrtTimer, and wrtMaxChains. portcfg ficon ge0 config -x 1 -w 1 396 Configuring and monitoring FCIP extension services
