1 Flows Flows A flow is a set of Fibre Channel (FC) frames or packets that share similar traits, such as an ingress port or egress port identifier or any other data that can be used to differentiate one set of related frames or packets from a different set. These parameters are specified as part of the flow command, and include: • Port parameters: (also called the Point of Interest, or where the data you want to examine is from) This consists of an ingress port (ingrport) or an egress port (egrport).
Flows 1 When creating or viewing a flow, you can specify any combination of the three features in the flow command. For example: flow --create flowname -feature monitor,generator flow --show flowname -feature mirror,generator Flow definition rules The rules listed in Table 1 identify what parameters can be used to define a flow.
1 Flows Flow frametype parameters Frame monitoring can be done for a variety of frames using predefined -frametype parameters. Table 3 list these parameters and the frames counted for each. On 8 Gbps-capable Fibre Channel platforms, possible frame monitoring flow classifiers include egrport, dstdev, and lun. On 16 Gbps-capable Fibre Channel platforms, including the Brocade FC8-32E and FC8-48E blades, possible frame monitoring flow classifiers include ingrport, egrport, dstdev, srcdev, and lun.
Flows 1 Numbers of flows supported Flow Vision supports a maximum of 512 flows on chassis-based platforms and a maximum of 128 flows on fixed-port platforms. However, there is a combined limit from all features of 64 flows (including static flows, root flows, and sub-flows, whether active or inactive) for any one port. In addition, there are individual limits for each Flow Vision feature; Table 4 lists these limits.
1 Flow Vision references The following example displays all the existing flows on the switch.
Flow Vision references 1 Firmware upgrading and downgrading and Flow Vision There are no restrictions on upgrading the firmware of a switch that has Flow Vision installed. Downgrading the firmware on a switch with Flow Vision installed will fail if any Flow Vision-related configurations are present on the switch being downgraded. All Flow Vision-related flows or simulation ports must be deleted prior to performing a downgrade to any version of Fabric OS prior to version 7.2.

2 Flow Monitor management Flow Monitor management The following sections describe how to manage the Flow Monitor feature. Creating Flow Monitor flows To create a Flow Monitor flow, enter the flow --create flowname -feature monitor parameters command using the parameters in Table 5. Figure 1 on page 2 illustrates how the frame and port parameters apply to a flow. Table 5 shows the supported Flow Monitor flow parameter combinations.
Flow Monitor management 2 Creating an inactive flow in Flow Monitor To create an inactive Flow Monitor flow, enter the flow --create command with the -noactivate keyword. flow --create flowname -feature monitor flow_parameters -noactivate Refer to “Activating Flow Monitor flows” on page 11 for information on activating a Flow Monitor flow. The following example creates an inactive Flow Monitor flow named “sflow8” from device 020a00 to device 01c000 ingressing through port 10.
2 Flow Monitor management Viewing Flow Monitor flows To display Flow Monitor flows, enter flow --show flowname -feature monitor.

3 Flow Generator management Flow Generator flows are defined using a combination of the source device (srcdev), destination device (dstdev), ingress port (ingrport), and egress port (egrport) parameters.All of these must be SIM-Ports. The source device is the origination point of the test traffic. The destination device is the destination of the test traffic; for Flow Generator flows it may be remote from the switch.
Flow Generator management 3 Parameter usage exceptions • If the srcdev and ingrport parameters are both defined, they must both be local to the switch and refer to the same source. • If the dstdev and egrport parameters are both defined for the flow, they must both be local to the switch and represent the same destination.
3 Flow Generator management When a flow is activated, traffic is generated by the ingress port or source device for that flow and any sub-flows associated with it as soon as all SIM-Ports and devices defined in the flow are online. The following example activates the Flow Generator flow named “Flow1”. switch:admin> flow --activate Flow1 -feature generator NOTE A flow can be activated with SIM-Ports that are offline or which have not been created.
Flow Generator management 3 Definition: IngrPort(1/9),SrcDev(0x010900),DstDev(0x01c100) Flow Generator (Activated): ----------------------| SrcDev | DstDev | ----------------------| 0x010900 | 0x01c100 | ----------------------Number of frames generated from IngrPort : 595.41M Note: More than 1 flow active on this port.
3 Flow Generator management Notes on displaying the status of a Flow Generator flow • If you want to see the per-flow frame count on a port with multiple flows, you must include the flow monitoring feature in the flow definition (flow --create flowname -feature generator, monitor). • If there is more than one static flow active on the port, Flow Generator will append a note stating such at the bottom of the output.
Flow Generator management 3 Resetting Flow Generator flow statistics To manually clear the frame count statistics for a Flow Generator flow, enter flow --reset flowname -feature generator. The following example clears the statistics for the Flow Generator flow named “Flow1”. switch:admin> flow --reset Flow1 -feature generator Customizing Flow Generator flows Flow Generator allows you to specify the frame payload size and pattern to be used for the Flow Generator flows by using the flow --control command.
3 Flow Generator examples Changing a flow frame payload pattern Assigning a frame payload pattern explicitly to a flow affects only that flow and overrides the existing frame payload pattern for that flow. Changing a payload pattern can only be done to an inactive flow. The following example sets the default payload pattern for the flow F2 to “a5a5a5”.

3 Flow Generator references • SIM-Ports cannot be configured as any of the following port types; these restrictions also apply at the time a SIM-Port is enabled: - Any port running Encryption or Compression Any F_Port connected to a real device (unless the port is disabled) D_Port (Diagnostic Port) E_Port EX_Port F_Port trunked Fastwrite port FCoE port ICL port L_Port M_Port (Mirror Port) VE port • The following features of a SIM-Port are persistent across a reboot: - Each SIM-Port is assigned a PID an
Flow Generator references 3 Flow Generator and MAPS MAPS can be used to monitor SIM-Port traffic thresholds while Flow Generator flows are running. Because MAPS treats SIM-Ports as F_Ports, MAPS can issue warnings on these ports if threshold values are triggered. If you do not want to see MAPS warnings for SIM-Ports, disable MAPS monitoring for those ports. Flow Generator traffic will also impact E_Ports; this may cause MAPS warnings for E_Port throughput levels.

4 Flow Mirror management Figure 10 provides a diagram of a mirrored flow with the ingrPort mirroring the traffic flow to the CPU. Flow Mirror can also mirror the egrPort, but only one port (ingrPort or egrPort) can be mirrored per flow. To mirror from one port in both flow directions (left to right and right to left), you must use the -bidir option. FIGURE 10 A flow being mirrored to the CPU Flow Mirror management The following sections describe how to work with Flow Mirror.
Flow Mirror management 4 The following example creates a Flow Mirror flow named “Flow1” that monitors all traffic flowing from device 010403 to device 020504 ingressing through port 10 on the switch on which this command was run. switch:admin> flow --create Flow1 -feature mirror -ingrport 10 -srcdev 010403 -dstdev 020504 When you create a flow, it is automatically activated unless you use the -noactivate keyword as part of the flow --create command.
4 Flow Mirror management Viewing Flow Mirror flows The following sections describe the different ways you can view Flow Mirror flows. Summary information view of a Flow Mirror flow To display the summary view of Flow Mirror flows, enter flow --show flowname -feature mirror. In the summary information view, the first output line lists the flow name and the flow features; the second line lists the source and destination devices and ports, and the flow’s directionality.
Flow Mirror management 4 In the verbose information view, the first output line lists the flow name and the flow features; the second line lists the source and destination devices and ports. The following lines list for each frame the time stamp of the frame, the direction of the frame, the start of frame and end of frame values, the frame type, and the first 64 bytes (16 words) of the frame.
4 Flow Mirror management The following example shows the frame rates for the Flow Mirror flow named “fmshow” at 10-second intervals. In this output at the beginning of t (time), the frame rate is not displayed, but at t+10, t+20, and so on, the frame rate is displayed. This rate is based on the difference between the cumulative number of frames mirrored within the specified interval.

4 Flow Mirror management Deleting Flow Mirror flows To delete a Flow Mirror flow, enter flow --delete flowname. You do not need to include -feature mirror, as you can only delete the entire flow; you cannot delete an individual feature from a flow. Deleting a flow automatically clears all the flow statistics for that flow. Deleting an active flow automatically deactivates the flow before it is deleted. The following example deletes the Flow Mirror flow named “Flow1”.
Troubleshooting using Flow Mirror 4 Troubleshooting using Flow Mirror The following use cases describe how to use Flow Mirror to troubleshoot typical fabric performance problems. Using Flow Mirror to diagnose SCSI reserve and SCSI release performance If there is excessive SCSI reserve and release activity in a virtualized environment, you can use Flow Mirror to identify the affected LUNs.
