  1. 3COM link aggregation

    Вверх!
  2. Подскажите, может кто сталкивался с проблемой, У 3COM теперь поддержка платная, даже bug request по прошивке сделать некуда, только остался форум между юзерами, да телефон, если совсем все сгорело... Не хочет у нас работать static link aggregation между гигабитными портами 3COM 4500 (3CR17562-91) и 4500G (3CR17761-91) Установлены свежие прошивки на обоих коммутаторах. Версии прошивок 4500 - V3.03.02s168 , 4500G - V5.02.00s168p01 В man вообще полный аскетизм - создайте группу, назначьте нужные интерфейсы в группу, вроде бы все просто, но... Пробовал dynamic aggregation - в терминал 4500 сыпет сообщения о том,что LACP disabled on the remote port. В Release notes к новой прошивке 4500G есть уточнение, что LACP теперь в прошивке отключен и построить dynamic aggregation между этими коммутаторами теперь нельзя в принципе. Рекомендовали перейти с dynamic на static aggregation Ниже приведены статусы интерфейсов и конфигов для aggregated link в режиме static.
