Буквально несколько дней назад, в середине недели, компания Mikrotik анонсировала новостную рассылку №79 (за декабрь 2017). В рамках рассылки было упомянуто обновление RouterOS до версии 6.41.
Честно говоря, лично у меня были большие сомнения, что компания выпустит обновление в преддверии Нового года, т.к. лишняя спешка с такими вещами вовсе ни к чему. Некоторые предыдущие обновления яркий тому пример.
Компания таки решилась выпустить финальную версию обновления RouterOS 6.41. Что же такого интересного в этом обновлении и почему его многие ждут с нетерпением? Попробуем разобраться.
RouterOS версии 6.41 содержит в себе новую реализацию моста (Bridge), которая уже поддерживает аппаратную разгрузку – hw-offload (hardware offload).
При выполнении обновления будет выполнено преобразование всех интерфейсов с «master-port», при этом сама опция master-port упраздняется как таковая. Ниже на скриншоте пример того, как конвертируются интерфейсы.
Обратите внимание! В случае понижения версии или отката (downgrade), это не приведет к восстановлению прежней конфигурации с master-port, вместо этого вам потребуется восстановить конфигурацию вручную либо при помощи бэкапа.
После чего в консоль будет выведен список команд для восстановления конфигурации, не забудьте их сохранить. Можно и сразу сохранить в rsc-файл, например так:
После этого можно приступить к обновлению.
Новый мост реализует обработку Layer2 и при соблюдении определенных условий будет автоматически включать hw-offload (если это возможно). Прочая конфигурация Switch не затрагивается и остается без изменений.
Пришло время ознакомиться с полным списком изменений, который включает очень много интересных изменений и не ограничивается одними только бриджами.
