Добрый день форумчане. Возможно у кого то уже была данная проблема с оборудованием brocade, поделиться решением.

Перешли с софтового роутера , на 10G Brocade VDX6720-24. Подняли BGP дефолт на трех соседей, один основной, и два резервных. Все зарабортало. Но периодически отваливается сессия. Может раз в несколько дней, а может дважди в сутки.

Нагрузка на память и загрузку процессора, мониторятся, нагрузка минимальная.

СФП меняли, проблема не ушла. 

Может кто что подскажет по настройке. Кто имеет опыт по настройке brocade.

В порядке бреда:
  

 timers keep-alive 60 hold-time 180

У аплинков  цифры такие же?
Ошибки на интерфейсах есть? 
Уровни по ddm в норме?

У разных аплинков , разные показатели. Я так понимаю, идет автосогласование.

Кстати, как раз у основного аплинка показатели 60 180.

Ошибки есть, немного. Но меняли пару SFP+ , и патчкорд. Все то же. Сбрасывал счетчики, и на нуле ошибок был отвал.

А зачем proxy arp в сторону аплинков?

Стояло по дефолту. Думаете в этом проблема?
