Prerequisites
WACs in this document refers to independent WACs, but not native WACs on switches.
You have basic knowledge of the naming mode of WAC and AP versions. WAC and AP versions are in VRC format, for example, V200R020C00 and V200R020C10.
In this naming mode, the version with a smaller number is earlier than the version with a larger number. In addition, the numbers may be inconsecutive. For example, a later R version of V200R010 is V200R019.
