 Catalyst 3750 и vlan bridging,  Harunaga, 26-Янв-07, 09:24 [смотреть все]В коммутатор 3750 приходит транк с кучей виланов, нужно некоторые из виланов между собой прозрачно сбриджевать (например, vlan 50 и 51).Создаю такую конфигурацию, форвардинг не работает, хотя sh bridge показывает, что таблица заполнена: c3750#sh bridge 1
