This section will introduce how to write a Qapp to analyze and troubleshoot inconsistency problems between neighbor devices. For example, the mismatched MTU values for neighbor interfaces as follows:

To create a Qapp to compare MTU and bandwidth values between two connected interfaces, complete the following steps:

1.Build Device Pairs in Device Queue.

2.Retrieve MTU and bandwidth Data of Device Pairs.

3.Configure Neighbor Join Operator for Data Comparison in One Table.
