portCfgEXPort 2 portCfgEXPort Sets a port to be an EX_Port, and sets and displays EX_Port configuration parameters. SYNOPSIS portcfgexport [slot/]port 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] DESCRIPTION NOTES 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. FCR supports Network OS edge (NOS) fabric connectivity when the EX_Port is set to Brocade Network OS fabric mode. No Integrated Routing License is required to support Network OS fabric connectivity, and selective device sharing will be allowed even when a license is not present. 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 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 EX_Ports are auto-ELP enabled.
