Over the past decade, numerous tools have been developed to check the correctness of router configurations. However, there seems to be a gap between the information these tools provide and the information required to fix the configurations. As part of an ongoing research project at Colgate University, we seek to better understand how network engineers currently locate errors in router configurations. We would appreciate if you could take 2 minutes to complete our anonymous, 10-question survey: https://colgate.co1.qualtrics.com/jfe/form/SV_e3CQ3JMfCnLJHTL If you are willing to share more about your experience with configuration errors and/or current network analysis tools, please let us know.
