Добрый день!
Прошу помочь разобраться со следующей проблемой:
Есть DGS-3612G - Firmware Version : Build 2.81.B03
Есть DES-3028 - Firmware Version : Build 2.60.B02
Соединил DGS-3612G с DES-3028 двумя шнурками (1 порт в 25 порт и 2 порт в 26 порт соответственно)
Поднял MSTP, настроил DHCP Relay.
На DGS-3612G

Все прекрасно работает.

Управление обоими свитчами есть, DHCP Relay работать перестает.
Снова соединяю 1 линк - DHCP Relay все равно не работает!
Помогите определиться что я делаю неправильно!
Спасибо!
