Cat3850 InService Upgrade

Стэк коммутаторов 3850 можно апгрейдить без даунтайма, если обновление идет в пределах минорных версий или билдов.

Сперва качаем и инсталлим софт стандартным рекомендованным способом. Ждем отработки всех этапов, следим за ошибками, в конце отказываемся от перезагрузки (либо просто в команде ключ no-reload используем).

P.S. так же с минимальным даунтаймом можно грейдить коммутаторы между мажорными релизами и фичесетами. Релоадим один, ждем на консоли когда он напишет по software mismatch, и грузим второй. Пока второй пройдет полную перезагрузку, первый уже обновленный довольно быстро вернется в строй.
