Добрый день! Вопрос такой.
Надо на дес 3526,3550 закрыть возможность поднятия дхцп сервера на клиентских портах 1-24 , а разрешить только на 25,26 портах (магистральныэ). Делаю так, в DHCP Server Screening Setting на порту 1-24 Enabled. Правильно ли я делаю?

Правильно или вот такие ACL http://www.dlink.ru/technical/faq_hub_switch_66.php

Блин, чтото не то, включаю DHCP Server Screening на портах 1-24 и клиенты не могут получить айпишник автоматом, как только деактивирую ету функцию на етих портах , все ок. В чем проблема подскажите плиизз??? Прошивка самая свежая. На дес 3550 все работает без проблем.

Пришлите пожалуйста конфиг устройства слитый по TFTP.
