If you are already classifying TCP/UDP ports, PacketShaper is unable to further classify this type of traffic. Class discovery is not applicable in this case. Older versions of PacketWise permitted this setting, so after upgrading, you may see this error.
How to resolve this issue:
1. In the PacketShaper CLI, issue the banner show command. You will see the "Configuration error" message. 2. Download config.ldi from your PacketShaper and remove the line iqosDiscoveryMode: both. 3. Upload the modified config.ldi file to your PacketShaper. 4. Issue the class load config.ldi CLI command. 5. The banner show output should no longer show the configuration error message.
