Optional arguments for fciptunnel create and modify include:
-n remote_wwn Specifies the remote-side FC entity WWN.
-d description Specifies a descriptor for the FCIP tunnel, for example, "Tunnel 0 to San
Jose Office".
-c 0|1 Disables (0) or enables (1) compression on the specified tunnel. By
default, compression is disabled.
-f 0|1 Disables (0) or enables (1) FastWrite on the specified tunnel. By default,
FastWrite is disabled.
-t 0|1 Disables (0) or enables (1) read/write Tape Pipelining on the existing
tunnel (requires FastWrite to be enabled).
-k timeout Specifies the keep alive timeout, in seconds. Timeout values are 8 to
7,200. The default is 10. If Tape Piplelining is enabled, the minimum
supported value is 80.
-M 0|1 Enables (0) or disables (1) default VC QoS mapping on the specified
tunnel. By default VC QoS mapping is disabled. There are two ways of
prioritizing network traffic over FCIP tunnels: Differentiated Services
(DSCP) and Layer 2 Class of Service (L2CoS). If the -M option is set, the
VC on the FCIP outbound frame is mapped to both a DSCP and L2CoS
value. These default values can be modified on a per-FCIP tunnel basis
with the fciptunnel qosmap option. The -M option can be turned on or off
any time. QoS map settings are unaffected by the -M option.
-q control-dscp Specifies the DSCP (DiffServ Code Point) marking used for the TCP
connection of the FCIP tunnel. This operand is optional. The range is 0 -
63. The default value is 0.
-Q data-dscp Specifies the DSCP (DiffServ Code Point) marking used for the data TCP
connection of the FCIP tunnel. This operand is optional. The range is 0 -
63. The default value is 0.
-m time Specifies the minimum retransmit time, in milliseconds. The range is
20ms to 5000ms; the default value is 100ms.
-r retransmission
Specifies the maximum retransmissions. Values are 1 - 16. The default
value is 8. If Tape Piplelining is enabled, the default value is calculated
based on the minimum retransmit time to ensure that the TCP
connection does not time out before the host times out. The specified
value must be greater than the calculated value.
-s 0|1 Disables (0) or enables (1) selective acknowledgement code (SACK) on
the specified tunnel.
-t 0|1 Disables (0) or enables (1) read/write Tape Piplelining on the specified
tunnel (requires Fastwrite to be enabled).
-v vlan_id Creates an FCIP tunnel with VLAN Tagging and Class of Service (CoS).
Specify a vlan_id in the range between 1 and 4094. There is no default. If
any other VLAN option is specified, the VLAN ID must also be specified.
The following operands are optional with VLAN tagging:
