2 portCfg --disable --enable Valid modes for rscnsupr are: Disables the configuration. When disabled, device changes on the port generate RSCN to another end device that is zoned with this one. By default, RSCN suppression is disabled on all ports. Enables the configuration. When enabled, any device changes on the port will not generate RSCN to any other end device. mirrorport --disable --enable Configure mirror port on the local port.The port mirroring feature reroutes data frames between two devices to the mirror port. Port mirroring can aid in troubleshooting common FC end-to-end communication problems. the command prompts for confirmation that the specified port will be enabled as a mirror port. Once a port is configured as a mirror port, the port can only be used as part of a mirror connection. The syntax for portcfg mirrorport is as follows: portcfg mirrorport [slot/][ge]port mode Valid modes for mirrorport are: Disables the configuration. When disabled, a port can not be a mirror port. Enables the configuration. When mirrorport is enabled to a port, a mirror connection can use this port to mirror traffic. fastwrite --enable Configures the FC port for FC Fastwrite. Enables ordisables FC Fastwrite between two Brocade 7500 routersor two Brocade 48000 directors with FR4-18i bladesconnected by Fibre Channel ISLs. FastrWrite mitigateslatency effects on SCSI writes, and improve throughputover a high-latency link. The blade first should be enabled for FC fastwrite using fastWriteCfg. This command can also be used to list all ports configured for FC fastwrite. This feature requires a Brocade license. 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. --disable Disables FC fastwrite on the specified port. vlantag Use this command to maintain the VLAN tag table associated with a particular network interface. This table is mainly used by ingress processing to filter VLAN tagged frames. If a VLAN tagged frame is received from the network and there is no entry for the VLAN ID, the frame will be discarded. There is no ingress filtering on the destination IP address. There can be multiple VLAN IDs per IP interface; however, there cannot be two entries to the same destination, including 0.0.0.0. On egress, this table is used to determine whether to tag a frame that is not already marked as tagged. Egress frames already marked as VLAN tagged (i.e. FCIP) will take precedence over entries in this table. 428 Fabric OS Command Reference 53-1000599-01
