2 portCfg 644 --write-timer value Defines a time limit for pipelined write chains. This value is 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 to 1500. --write-chain value 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 value is 3.2 MB (3200000 bytes) The range is 1 MB to 5 MB. --oxid-base value 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 0x8000 (recommended setting). The range is 0x0000 to 0xF000. --ficon-debug value Defines optional debug flags. The default value is 0xF7C80000. This parameter is primarily for use by technical support personnel. Optional FCIP circuit arguments for fciptunnel create and modify include the following. -a | --admin-status [0|1] Enables (1) or disables (0) the circuit. Admin status is disabled by default. Use -a --admin-status to enable the feature when you create a circuit. Use -a |--admin-status 0|1 when you modify a circuit. -C | --connection-type [0|1|2] | [default|listener|initiator] Specifies whether the circuit is the listener or the initiator. Values are 0=Default, 1=Listener, and 2=Initiator. You can use either the numeric values or their string equivalents. String values are not case sensitive. In default mode, the initiator and listener are automatically chosen based on the lower and higher-order IP address. This can cause a problem in Network Address Translation (NAT) environments, if both sides of the circuit have lower-order addresses. This option is a disruptive modify request that causes the tunnel to bounce. The command prompts for confirmation with an appropriate message. -s | --sack 0|1 Disables (0) or enables (1) selective acknowledgement code (SACK) on the FCIP circuit. SACK is enabled by default. Use -s | --sack to disable the feature when you create a circuit. Use -s | --sack 0 | 1 to disable or enable SACK when you modify a circuit. -k | --keepalive-timeout timeout Specifies the keep alive timeout in milliseconds. The valid range is 500 ms to 720000 ms. If the tunnel does not already have FICON Emulation enabled, circuits created on the tunnel default to 10000 ms (10 seconds) for the FCIP Trunking keep alive timeout. If FICON emulation is enabled on the FCIP Tunnel when a circuit is created, the keep alive timeout defaults to 1000 ms (1 seconds). -x | --metric metric Specifies the metric for the configured circuit. The valid range is 0 to 1. The default value is 0. A lower metric assigns a higher priority to the circuit. As data is flowing through the FCIP tunnel, it automatically traverses the lowest metric cost circuits. For example, if a tunnel has four circuits, three of which Fabric OS Command Reference 53-1002746-01
