--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
