-s |--sack 0|1 Disables or enables selective acknowledgement code (SACK) on the FCIP
circuit. Note that SACK is by default enabled. Use -s | --sack to disable
the feature when creating a circuit. Use -s | --sack 0 to disable and -s |
--sack 1 to enable SACK when modifying 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 are set to a metric of 0 and one is set to a metric
of 1, all data will flow over the metric 0 circuits. If all of the metric 0
circuits go down, traffic will run over the metric 1 circuits. This parameter
is meaningful only, if you configure more than one circuit.
-m |--min-retrans-time time
Specifies the minimum time interval in milliseconds between
retransmits. The valid range is 20 ms to 5000 ms. The default value is
100 ms.
-r |--max-retransmits retransmissions
Specifies the maximum number of retransmissions. The valid range is 1
to 16. The default value is 8.
-v |--vlan-tagging 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. If any other VLAN
option is specified, the VLAN ID must also be specified. Refer to the IEEE
802.1p specification for more information.
You can configure VLAN tags when you create a circuit or after the fact by
modifying a circuit. Note that adding or modifying the VLAN configuration
after a circuit has been created is a disruptive operation.
You may also specify VLAN tagging per IP interface with the portCfg
vlantag command.The VLAN configuration at the IP interface level is for
non-data path traffic only. If the data path traffic is to be tagged, it must
be done through the VLAN tagging option with the fcipcircuit create or
modify command. Note that the circuit VLAN configuration takes priority
over the IP interface VLAN configuration.
The following operands are optional with VLAN tagging:
--
l2cos-f-class l2cos
Specifies the Layer 2 Class of Service (L2CoS) value for F-Class Traffic.
This priority setting controls connections between switches. The range is
0 to 7. The default is 0.
