portCfg
-C | --connection-type [default | listener | initiator]
Specifies whether the circuit is the listener or the initiator. 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.
-L | --load-leveling [default | failover | spillover]
Configures spillover or failover load-balancing method. The default load-balancing
method is failover. This argument is applicable on the Brocade 7840 switch and the
Brocade SX6 extension blade only.
-s | --sack [disable | enable]
Disables or enables selective acknowledgement code (SACK) on the extension circuit.
SACK is enabled by default. Use -s | --sack to disable the feature when you create a
circuit. Use -s | --sack disable | enable to disable or enable SACK when you modify a
circuit. This operand is supported on the Brocade FX8-24 blade only.
-k | --keepalive-timeout timeout
Specifies the keep alive timeout in milliseconds. The valid range is 500 ms to
7200000 ms. If the tunnel does not already have FICON Emulation enabled, circuits
created on the tunnel default to the the keep alive timeout of 10000 ms (10 seconds)
for Brocade FX8-24 blade and 6000 ms (6 seconds) for Brocade 7840 switch and
the Brocade SX6 extension blade. If FICON emulation is enabled on the extension
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 extension 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 extension 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 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 FX8-24 blade only.
