Example: Troubleshoot Traffic Issues Between Side A and Side B

This section provides you an example of how to troubleshoot a specific issue using the flexible inline canvas.

Consider that you have an inline network IN1 with one by-rule map and one collector map. The traffic is not flowing from Side A to Side B. To troubleshoot this issue:

Go to Physical > Inline Flows.

Select the required device, and then drill down to the inline network that has the traffic issue.

Click Status to view the forwarding states of the inline network. Ensure that the forwarding state of the inline network is Normal. For details of the forwarding states, refer to View the Forwarding States of Inline Networks.

Click Statistics to view the total packet count of the inline network. The Rx count of Port A of the inline network must match the Tx count of Port B. If the count does not match, the traffic is blocked between Port A and Port B.

Note: To refresh the statistical data, click Statistics again.

Click Troubleshoot to view the configurations of the by-rule and collector maps configured for the inline network.

Check that the by-rule map has packet count.

If the by-rule map has packet count, check the inline tools from A to B and B to A directions of the by-rule map to ensure that the inline tools are in up state and the Flex Traffic Path is set to To inline tool.

Click Statistics to view the port statistics of the required inline tool. If the Rx count of Port A of the inline tool does not match the Tx count of Port B of the inline tool, the traffic is dropped at the inline tool. Check the inline tool and take the required action.

If the Rx count of Port A of the inline tool matches the Tx count of Port B of the inline tool, repeat steps 5 and 6 for the collector map configured for the inline network.

If the Rx count of Port A of the inline tool configured for the collector map matches the Tx count of Port B of the inline tool, contact Gigamon Technical Support.
