flow Notes This command requires a Fabric Vision license. The execution of this command is subject to Virtual Fabric restrictions that may be in place. Refer to "Using Fabric OS Commands" and "Command Availability" for details. Function Creating a flow Synopsis flow --create flow_name -feature feature_list port_options frame_options [config_options] Description Operands Use this command to create a flow and by default activate the flow for the specified features. This command validates the flow definition before creating a flow. If the flow definition is not supported by any specified feature or if the flow definition is a duplicate of an existing active flow, the operation will terminate with an appropriate error message. For more information on duplicate flows, refer to the Fabric OS Administrator's Guide. The following rules apply for creating a flow: • You must specify at least one port option (-ingrport or -egrport) but not both. • You must specify the source device (-srcdev), the destination device (-dstdev), or both. The source device and the destination device can be learned using a wildcard ("*"). • The ingress port and egress port must reside in the local switch. • The source device and destination device can reside in either the local or remote switch. • You can create 512 flows on a Brocade director and 128 flows on a switch-based system. Note that each flow discovered when using "*" as a source device or destination device will count as one of these flows. These system-discovered flows will impact the number of user-defined flows allowed to be active. • The configuration options -noactivate, -noconfig, and -bidir are optional. • You can create up to 64 monitor flows and four generator flows per port. • You can activate one mirror flow per chassis or switch-based system. The --create command has the following operands: flow_name Specifies the name of the flow. Each flow name must be a unique string composed of a maximum of 20 alphanumeric or underscore characters. The flow name is case-insensitive and is always stored as lowercase. -feature feature_list Specifies a comma-separated list of features to activate for the flow. Specify "all" to activate all features for a flow. Valid values for feature_list include the following: monitor Activates the Flow Monitor feature for a flow. The Flow Monitor feature monitors and provides statistics for the specified flow. 352 Brocade Fabric OS Command Reference 53-1004112-02
