Приветствую, коллеги,В отсутствии админа вылезла проблема между одним из удаленных филиалов и центральным офисом
Имеется в филиале cisco WS-C4503 и в центральном офисе cisco WS-C4506-E
между ними прозрачный канал вроде как е1
настройки 4503 - филиал

Замеряю скорость на канале утилкой NetCPS, со стороны центра туда лльется со скоростью 30 кбсек, обратно 650 кбсек, провайдер проверил канал, утверждает что у них 10мбсек.
Нагрузки на канале давно не было и сложно сказать, появилась ли проблема внезапно, либо так и было. Сейчас начали разворачиваться в этом филиале и вот такая петрушка.
Кстати по CDP девайсы друг друга не видят.
Что смотреть? Простите нуба.
