portCfg 2 -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. -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. --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. --l2cos-low l2cos Specifies the L2CoS value for Low Priority Traffic. The range is 0 to7. The default is 0. Fabric OS Command Reference 53-1003108-01 699
