Реализация связки Dlink DGS-3610-26G + DES-1228G(vlan на клиента) на основе схемы Cisco2 + Zyxel ( DGS-3610-26G + DES-1228G )

Подключение абонентов по схеме "vlan-на-клиента", Это замена стандартной схему Cisco2 + Zyxel ( DGS-3610-26G + DES-1228G ). При этом используется оборудование D-Link - на уровне доступа свитчи DES-1228G, в ядре - DGS-3610-26G. И еще в отличи от стандартной схемы порты берутся ни из редактора шлюза Zyxel, а универсальный со вкладки порты в договоре .


Управление осуществляется по telnet. К сожалению в используемом оборудовании функционал "ip unnumbered" реализован не так как в коммутаторах Cisco, поэтому использовать его не получится. Работать необходимо используя технологию supervlan. В кратце - эта технология позволяет задавать допустимые IP-адреса для конкретного vlan, при этом закрепить можно только диапазон состоящий минимум из 2-х адресов. Например: 

            DGS-3610# configure
            DGS-3610(config)# vlan 1000
            DGS-3610(config-vlan)# subvlan-address-range 192.168.100.10 192.168.100.11
            DGS-3610(config-vlan)# end
