I will start off by saying that I am no YANG expert. Nor am I an expert on microwave radio links in spite of being involved in deploying a number of them in the late 1980s. (but this module would have been useful at that time to understand what was going on when things got fuzzy - which they did from time to time) That said, this is a very well written document – very clear and easy to follow. I see no non-ops issues with the document. I also see no op-related issues – indeed it is good ops-wise to be able to understand the state of devices in a network and to be able to manage their configuration. Scott
