2 portCfg 584 --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 Mb (3000000 bytes) The range is 1 Mb-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 0x1000. 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 ID 0 arguments for fciptunnel create and modify include: -a |--admin-status 0|1 Enables (1) or disables (0) the circuit. -s |--sack 0|1 Disables (0) or enables (1) selective acknowledgement code (SACK) on the FCIP circuit. SACK is by default enabled. -k |--keepalive-timeout timeout Specifies the keep alive timeout in milliseconds. The valid range is 500ms - 720000ms. The default value is 5000ms. -x |--metric metric Specifies the metric for the configured circuit. The valid range is 0 - 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 five circuits, three of which are set to a metric of 0 and two are set to a metric of 1, all data will flow over the metric 0 circuits. This parameter is meaningful only if you configure more than one circuit. -b | --min-comm-rate minimum Modifies the minimum committed traffic rate on the FCIP circuit 0 in Kbps. -B | --max -comm-rate maximum Modifies the maximum committed traffic rate on the FCIP circuit 0 in Kbps. -m |--min-retrans-time time Specifies the minimum time interval in milliseconds between retransmits. The valid range is 20ms - 5000ms . The default value is 100ms. -r |--max-retransmits retransmissions Specifies the maximum number of retransmissions. The valid range is 1 16. The default value is 8. If Tape Pipelining is enabled, the default value is calculated based on the minimum retransmit time to ensure that the tunnel does not time out before the host times out (at least 80 seconds). If you choose to modify this value, the specified value must be greater than the calculated value. Fabric OS Command Reference 53-1001337-01
