Troubleshooting Integrated Traffic Monitoring

The following is sample output from the show ip flow top-talkers port command:

Debug Commands

Debug commands are another useful tool in diagnosing problems within the ITM configuration. By

enabling debug commands, debug messages are sent to alert you whenever specified actions take place.

These messages can be beneficial when you are troubleshooting your configuration.

To receive notification whenever a message is sent from the FlowExport to an external data collector, use

the debug ip flow export command. This command indicates when traffic flows are exported and lets you

track which traffic flows are traveling to which destinations. The following is sample output from the

debug ip flow export command:

#debug ip flow export

#show run

ip flow export destination 10.22.22.254 3000

ip flow export vrf BLUE destination 172.16.4.5 65774

*Dec 18 22:45:43: IPFLOW: Sent export pkt #32958 to 10.22.22.254:3000

*Dec 18 22:45:43: IPFLOW: Sent export pkt #32958 to 172.16.4.5:65774 (BLUE)

To receive messages every time a traffic flow has expired from the flow cache, use the debug ip flow

cache expiration command. Using this command allows you to be notified each time a traffic flow has

expired and is being exported through FlowExport. This notification can be beneficial because it allows

you to verify that the traffic flow expiration time is set correctly, that the traffic flows are being expired

correctly, and that the number of forced expirations of traffic flows is not excessive.

Using debug commands can be very processor intensive, and should be used with caution.
