About WAN optimization diagnostics

On-screen diagnostic messages help you troubleshoot problems in the WAN Optimization Manager™ (WOM®) configuration itself, or in a connection, such as between the two endpoints, between a client or server and the adjacent BIG-IP® WOM, or another point in the routing setup.

WOM diagnostic error messages

This table describes the types of messages that appear when you run the diagnostic tools provided on the WAN Optimization Diagnostics screen.

Message Type Description
INFO For informational purposes, indicates, for instance, whether deduplication is enabled on the local BIG-IP WOM system.
OK A verification check for WOM configuration.
WARN Indicates that some functions might not be fully operational.
FAIL The highest severity level, displayed in red, indicates that WOM is not able to function. You must fix this problem before proceeding.

Troubleshooting network connectivity for WAN Optimization Manager

Before you start this task, you must have finished configuring WAN Optimization Manager™ (WOM®) on BIG-IP® systems on opposite sides of the WAN, and the systems have discovered their remote endpoints.
You can use these diagnostics from the local BIG-IP system to the remote server to verify the BIG-IP system-to-server routes, in case the remote BIG-IP system is not configured correctly.
  1. On the Main tab, expand WAN Optimization and click Diagnostics.
  2. In the Diagnose Network Connections field, type the IP address of a remote WOM endpoint, and click the Run button. Network connection diagnostic information appears on the screen. Use this information to determine whether there is a connection between the local endpoint and the remote endpoint you specify.
  3. Use the data displayed on the screen to make corrections.
  4. In the Ping field, type the IP address of a host, for example, a remote BIG-IP system, and click the Run button. Use this utility to determine whether other BIG-IP systems can be reached through the routed WAN network. If ping fails, verify the configuration of your VLANs, self IP addresses, and default gateway.
  5. Use the data displayed on the screen to make corrections, such as properly defining the local and remote routes. Ping results appear on the screen. If a ping fails, you can use Traceroute to pinpoint the location of a failure in the network.
  6. In the Traceroute field, type the destination IP address you want to reach, and click the Run button.
  7. Use the data displayed on the screen to correct any routing problems. This data can reveal whether the problem is in the WAN, or is local to either of the BIG-IP systems. You can also view the observed latency, if any, along the WAN path.

Running WAN optimization configuration diagnostics

Before you start this task, you must have finished configuring WAN Optimization Manager™ (WOM®) on BIG-IP® systems on opposite sides of the WAN.
The WOM configuration diagnostics verify that you have set up WAN Optimization Manager properly.
  1. On the Main tab, expand WAN Optimization and click Diagnostics.
  2. Next to Diagnose WOM Configuration, click the Run button to verify that BIG-IP WOM is configured correctly.
    Note: If you have not sent traffic through the designated network, dynamic discovery might not have discovered the remote endpoint.
    In the following example, the SDD codec mismatch on the peers causes a warning message, because WAN optimization features other than deduplication are functional.

  3. Correct any configuration errors as indicated on the screen.
  4. After you correct any errors, click the Run button to run the configuration diagnostics again.
  5. Repeat these steps on the BIG-IP WOM on the other side of the WAN to verify that the other WOM system is configured correctly.
