2 portCfgEXPort portCfgEXPort Synopsis Description Notes Sets a port to be an EX_Port, and sets and displays EX_Port configuration parameters. portcfgexport [slotnumber/]portnumber portcfgexport [-a admin] portcfgexport [-f fabricid] portcfgexport [-r ratov] portcfgexport [-e edtov] portcfgexport [-d domainid] portcfgexport [-p pidformat] portcfgexport [-t fabric_parameter] portcfgexport [-m port mode] portcfgexport [-i mode] Use this command to allow a port to be configured as an EX_Port, to display the port's EX_Port configuration, or to change the configuration. If no optional parameter is specified, the command displays the currently configured values; otherwise, it sets the specified attribute to its new value. The port must be disabled prior to setting EX_Port attributes. The port must be enabled before the port can become active following EX_Port parameter changes. Use portDisable and portEnable to disable or enable the port. IPFC over FCR allows the routing of IPFC traffic between different EX_Ports where EX_Ports are connected to an edge fabric that has IPFC-capable devices. IPFC traffic is routed between EX and VEX Ports. IPFC traffic can be related to the same edge fabric or to different edge fabrics. When the port is not active, the preferred domain ID is configurable. The preferred domain ID is used by the EX_Port's front phantom domain to request a domain ID from the principal switch. The domain ID received becomes the subsequent preferred domain ID, which is persistent and is displayed. Fabric OS v6.2.0 FCR supports FCR connections to McDATA Open Fabric Mode fabrics operating in 239 domain ID mode. The 239 DID mode is only supported on the Brocade Mi10k director. The portCfgExport command displays the Domain ID mode of the McDATA edge fabric. Refer to the example section for an illustration of this feature. The fabric ID must be the same for every router port connected to the same edge fabric, and different for every edge fabric. If two ports are connected to the same fabric but have been assigned different fabric IDs, one of them will be disabled due to a fabric ID oversubscription. If two fabrics have been assigned the same fabric ID, one of them will be disabled due to a fabric ID conflict. When a port is changed from FL_Port to EX_Port, the topology is implicitly changed to point-to-point. The front domain WWN field displays the WWN of the front domain. If the port is enabled and the state is "OK", the edge fabric principal switch's domain ID and WWN also are displayed. 604 Fabric OS Command Reference 53-1001337-01
