Checking Your Work

To verify that your configuration is correct, use the following commands on the monitoring station that is configured for active flow monitoring:

• show services accounting errors
• show services accounting (flow | flow-detail)
• show services accounting memory
• show services accounting packet-size-distribution
• show services accounting status
• show services accounting usage
  

  NOTE: Active flow monitoring operational mode commands contain equivalent output information to the following passive flow monitoring commands: show services accounting errors = show passive-monitoring error show services accounting flow = show passive-monitoring flow show services accounting memory = show passive-monitoring memory show services accounting status = show passive-monitoring status show services accounting usage= show passive-monitoring usage The active flow monitoring commands can be used with most active flow monitoring applications, including sampling, discard accounting, port mirroring, and multiple port mirroring. However, you can use the passive flow monitoring commands only with configurations that contain a monitoring group at the [edit forwarding-options monitoring] hierarchy level.

  
  

The following shows the output of the show commands used with the configuration example:
