Имеется Cisсo 7201, с некоторого времени происходит сброс PPPOE-соединений как на выносных станции так и на центральной, может быть как днём так и вечером, было подозрение образование петель в сети, поэтому на всем оборудовании были включены STP, не помогло идеи закончились, конфиг кошки не меняли началось резко не понять из за чего, идеи закончены осталась надежда только у вас подскажите в чём может быть проблема. Схема сети: Cisco7201-AT9724 Catalyst 3570G, в логи кошки видно спам надписей:
