portCfg 642 -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. Brocade Fabric OS Command Reference 53-1004112-02
