Привет!

Нет под ругой 35. На WS-2950T-24 EI есть такое: (config)#port-channel load-balance ? dst-mac Dst Mac Addr src-mac Src Mac Addr

Балансировать Dst и Src пробовали - эфекта нет. В конфиге ниже есть строка

port group 1 distribution destination

Ясно. Поставте на интерфейсах load-interval 30 Так нагляднее видно скоко ездит трафика.. Может не все так плохо. :) Если балансировка критична - то лучше ее сделать на роутерах.. С помощью eigrp например.

Тракн работает нормально. Проблема в том, что нет балансировки в каналах. Где рыть ?

Вот статистика по интерфейсам
