Brocade Flow Vision Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 22)

Viewing flows
Flow Vision allows you to view the configuration parameters for each flow on a switch.
• To display all Flow Vision flows, enter flow --show.
• To display all flows for a specific feature, enter flow --show -feature feature_name.
• To display the definition for a specific flow, enter flow --show flow_name -feature feature_name.
When you enter flow --show with a flow name, only the flow definition for the specified flow is
displayed. If the feature is also specified, feature-specific data is displayed for the specified flow
name. For root and static flows, this command shows the Source ID-Destination ID pairs and the
cumulative frame count for the ingress or egress port specified in the flow definition.
The following example displays all the existing flows on the switch.
switch:admin> flow --show

Flow Name | Feature |SrcDev | DstDev |IngrPt|EgrPt |BiDir|LUN |FrameType|SFID|DFID|MirPt |

The flow name with prefix sys_ denotes a predefined flow
Refer to the individual features to see feature-specific output.
Repeating flow output
You can configure the Flow Vision features to repeat their flow output. The purpose of repeating a flow
is so that you can view sample frames or output over time to look for differences. This allows you to
continuously monitor a changing situation.
To specify the number of times the flow output should be repeated, complete the following steps.
1. Connect to the switch and log in using an account with admin permissions.
2. Use the flow --show flow_name -feature feature_name -count num command. The num value can
range from 1 through 10. The default value is 1.
