Clearing the statistics for a specific flow feature
To clear the statistics for specified features of a flow, complete the following steps.
1. Connect to the switch and log in using an account with admin permissions.
2. Enter flow --reset flow_name -feature feature_list. Replace feature_list with either an individual
feature or a comma-separated list of features (for example, “generator,monitor” or “mir,mon”).
You will not be asked to confirm this action.
The following example clears only the Flow Monitor statistics for the flow named
“Flow4”.
switch:admin> flow --reset Flow4 -feature monitor
Flow Vision licensing
To run Flow Vision, you need either the Fabric Vision (FV) license, or both the Fabric Watch (FW) and
the Advanced Performance Monitor (APM) licenses. If you have both of these licenses, you do not
need a separate Flow Vision license.
Refer to the Fabric OS Software Licensing Guide for more specific information about licensing and
how to obtain the needed license keys.
Flow Vision configuration setup
When a switch goes offline or comes online, Flow Vision reads the configuration files and then deletes
flows, creates flows, and activates flows. After a switch goes offline, any flows that were active at the
time it went offline will be reactivated when it comes back online and new traffic will be generated as
soon as the source and destination devices defined in the flow are online. This includes predefined
flows.
Use the following commands to upload, download, and delete configurations:
• To download a Flow Vision configuration to the switch, use the configDownload command.
• To save the Flow Vision configuration to the host FTP site, use the configUpload command.
• To delete all flows and simulation ports (SIM ports) from a switch, use the configDefault command.
NOTE
Statistical data for flows is not saved in the configuration database.
