Хелло,

 

Сделаю репост, вчера не туда запостил.

Нарисовалась проблемка с дрожащей цыской 3560G. Проблема в том, что иногда обрываются ospf и bgp линки, и на саму цыску некрасивый пинг 0-100мс. Софт залили свежий.

Хеллоу,

 

По ходу дела пару Мбит мультикаста всё валило нафиг.

Теперь стоит вопрос о замене железа. Интересует которое из младшего железа умеет CoPP или аналог у других производителей. Может и full view bgp чтоб мог скушать.

 

Сенькю! :)
