2 portCfgVEXPort portCfgVEXPort Synopsis Description Notes Sets a port to be an VEX_Port, connected to a FC-IP and sets and displays VEX_Port configuration parameters. portcfgvexport [slotnumber/]portnumber portcfgvexport [-a admin] portcfgvexport [-f fabricid] portcfgvexport [-r ratov] portcfgvexport [-e edtov] portcfgvexport [-d domainid] portcfgvexport [-p pidformat] portcfgvexport [-t fabric_parameter] portcfgvexport [-m portmode] Use this command to allow a port to be configured as an VEX_Port, to display the port's VEX_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 VEX_Port attributes. The port must be enabled before the port can become active following VEX_Port parameter changes. Use portDisable and the portEnable to disable/enable the port. When the port is not active, the preferred domain ID is configurable. The preferred domain ID is used by the VEX_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. 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. 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. If the Fabric Parameter value is "Auto Negotiate", the port ID format, R_A_TOV, and E_D_TOV values display the negotiated values indicated by "(N)" next to them. The negotiated values are what the edge switch specifies in the ELP request. If the state is "Not OK", the R_A_TOV and E_D_TOV display "Not Applicable". By default, all VEX_Ports are auto-ELP enabled. If the Fabric Parameter attribute value is "User configured", the port ID format R_A_TOV and E_D_TOV values display the configured values. A configuration change that would result in an invalid domain ID for McDATA Open Fabric mode or McDATA Fabric mode will cause the preferred domain ID to be set to the minimum valid McDATA mode domain id of 1. The exception to this is if the configuration change includes setting the preferred domain ID, in which case the configuration change will not take place and a corresponding error message will be displayed. The execution of this command is subject to Admin Domain restrictions that may be in place. 464 Fabric OS Command Reference 53-1000599-01
