-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. This parameter is meaningful only, if you configure more
than one circuit.
-g | --failover-group failover_group_ID
Specifies the failover group ID for the configured circuit. The valid range is 0
to 9, where 0 is the default failover group. The circuit failover groups must be
defined at both ends of the FCIP tunnel and each failover group should
include at least one metric 0 and one metric 1 circuit. If all metric 0 circuits in
the failover group go down, the transmission fails over to the metric 1 circuits
in the group. If all metric 0 circuits in a tunnel go down, by default the traffic
will run over the metric 1 circuits.
-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. This operand is
supported on the Brocade switch 7800 and FX8-24 blade only.
-r | --max-retransmits retransmissions
Specifies the maximum number of retransmissions. The valid range is 1 to
16. The default value is 8. This operand is supported on the Brocade switch
7800 and FX8-24 blade only.
-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. This operand is
supported on the Brocade switch 7800 and FX8-24 blade only.
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.
--l2cos-high l2cos
Specifies the L2CoS value for High Priority Traffic. The range is 0 to 7. The
default is 0.
--l2cos-medium l2cos
Specifies the L2CoS value for Medium Priority Traffic. The range is 0 to 7.
The default is 0.
