portCfg 2 mirrorport --disable --enable Configure mirror port on the local port. The port mirroring feature re-routes 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 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. This command is blocked in Virtual Fabric mode. 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 cannot 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 --disable Configures the FC port for FC Fastwrite. Enables or disables FC Fastwrite between two Brocade 7500 routersor two Brocade 48000 directors with FR4-18i blades connected by Fibre Channel ISLs. FastWrite mitigateslatency effects on SCSI writes, and improves 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. 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 is 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) takes precedence over entries in this table. NOTE: This command supports --add and --delete options only. To modify a table entry it must first be deleted, then added with different configuration parameters.The syntax for portcfg vlantag is as follows: portcfg vlantag [slot/]port mode arguments Valid modes for vlantag are: --add ipif_addr vlan_id L2 CoS [dst_ipaddr] Adds an entry to the VLAN tag table.
