2 portCfg -r retransmissions Specifies the maximum retransmissions for the existing tunnel. Values are 1 to 16; default is 8. If Tape Piplelining is enabled, the default value is calculated based on the minimum retransmit time to ensure that the TCP connection does not time out before the host times out. When changing this value, the value specified must be greater than the calculated value. -s 0|1 Disable (0) or enable (1) selective acknowledgement (SACK) on the existing tunnel. -t 0|1 Disable (0) or enable (1) Tape Piplelining on the existing tunnel (requires Fastwrite to be turned on as well). -p Control L2 CoS -P L2 CoS Specifies the PL2_Class_of_Service/Priority, as defined by IEEE 802.1p, for the FCIP control connection. Range is 0-7. Default is 0. Specifies the PL2 Class of Service/Priority, as defined by IEEE 802.1p, for the FCIP data connection. Range is 0-7. Default is 0. -bstr 0|1 delete tunnel_id Disable (0) or enable (1) Byte Streaming on the existing tunnel. The feature is disabled by default. Deletes specified FCIP tunnel. qosmap tunnel_id arguments Modifies (or resets to default), the VC to QoS mapping for a particular FCIP tunnel. This table can be modified at any time without bringing down the tunnel. However, the FCIP tunnel must be configured with the fciptunnel create/modify -M option before the actual mapping occurs. The following operands are supported with fciptunnel qosmap: tunnel_id Specifies the tunnel_id. Range is 0-7. -default Resets/sets VC QoS map to default values. -delete vc_num Deletes associated QoS map configuration file. Delete QoS mappings before downgrading to pre-v6.0.0 firmware versions that do not support QoS mapping. It removes the file from the config flash memory only. The file is automatically reset to defaults if later used or modified. When modifying the VC QoS map, specifies the virtual channel ID for which the qosmap is modified. Valid values are 0 - 15. When specifying vc_num, either the -Q or the -P option or both must be specified. -Q dscp Specifies the Differentiated Services Code Point (DSCP) value to be modified. Use the portShow fciptunnel geport all -qosmap command to display current values. Supported range is 0-63. 542 Fabric OS Command Reference 53-1001186-01
