2 portCfg qosmap 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. The FCIP tunnel must be configured with the fciptunnel create/modify -M option before the actual mapping occurs. tunnel_id The following operands are supported with the fciptunnel qosmap option: Specifies the tunnel ID. The valid range is 0 to 7. -default Resets or sets the VC QoS map to default values. -delete Deletes the associated QoS map configuration file. You must delete QoS mappings before downgrading to pre-v6.0.0 firmware versions that do not support QoS mapping. This command removes the file from the configuration flash memory only. The file is automatically reset to defaults if later used or modified. vc_num When modifying the VC QoS map, specifies the virtual channel ID for which the QoS map 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 to 63. -P l2cos Specifies the L2 Class Of Service (COS) Tagging value. Use the portShow fciptunnel geport all -qosmap command to display current values. Supported range is 0 to 7. fastwrite --enable --disable Configures the FC port for FC FastWrite. Enables or disables FC FastWrite between two Brocade 7500 switches or two Brocade chassis with FR4-18i blades connected by Fibre Channel ISLs. FC FastWrite mitigateslatency effects on SCSI writes, and improves throughputover a high-latency link. The switch or blade must first be enabled for FC FastWrite using fastWriteCfg. You can also use this command to list all ports configured for FC FastWrite. The syntax for portcfg fastwrite is as follows: portcfg fastwrite [slot/]port mode Valid modes for fastwrite are: Enables FC FastWrite on the specified port. Disables FC FastWrite on the specified port. ficon Use this command to enable or disable FICON emulation in an FCIP tunnel and modify associated parameters onan FCIP tunnel on a VE_Port. A feature key is required to enable any of the FICON emulation processing. The tunnel must be down or disabled to issue and process the FICON commands. The results of this command are persistent. The syntax for portCfg ficon is as follows: portCfg ficon [slot/]Ge_Port tunnel_Id config |delete [FeatArgs] [ParamArgs] 632 Fabric OS Command Reference 53-1001764-02
