Кстати переделал с on на active (LACP) ситуация улучшилась, но переключение идет около 30 секунд, без агрегации (просто при STP) переключался за 15 секунд. Причем переключение идет как-то странно. Пингую один хост- отключаю порт пинг пропадает на 30-40 сек, однако если в это время начать пинговать другой хост пинги идут. Может действительно load-balance в другой режим переключить. И для ускорения переключения pvst на rapid-pvst поменять
