--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.
