-M [0|1]
Disables (0) or enables (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 Code Point (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 to 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 to 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 to 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 or enables selective acknowledgement code (SACK) on the
specified FCIP tunnel. Note that SACK is enabled by default. Use -s to
disable the feature when creating a tunnel. Use -s 0 to disable and -s 1 to
enable SACK when modifying a tunnel.
-t [0|1]
Disables (0) or enables (1) read/write Tape Piplelining on the specified tunnel
(requires FCIP 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:
-p Control l2cos
Specifies the L2 Class of Service/Priority for the FCIP control connection as
defined in the IEEE 802.1p specification. The range is 0 to 7. The default is 0.
-P l2cos
Specifies the L2 Class of Service/Priority for the FCIP data connection as
defined in the IEEE 802.1p specification. The range is 0 to 7. The default is 0.
-ipsec policy
_ID Specifies the Internet Protocol security (IPSec) policy number to be used
on the specified tunnel. This option must be used together with -ike and
-key.
-ike policy_ID vc_num
Specifies the Internet Key Exchange (IKE) policy number to be used on the
specified tunnel. This option must be used together with -ipsec and -key.
