Есть 2 коммутатора:
3200-10 (ip 192.168.40.3)
3526 (ip 192.168.40.4)
Данные свичи обьеденены общими vlan:
10 - manage
12 - clients
Подключены они магистральными портам на L3 коммутаторе с тегированными vlan на интерфейсах.
Пример на 3200:
Код:
config ipif System ipaddress 192.168.40.3/255.255.255.0
create iproute default 192.168.40.1
create vlan manage tag 10
config vlan manage add tagged 9,10
config ipif System vlan manage
create vlan 12 tag 12
config vlan 12 add untagged 1-8
config vlan 12 add tagged 9,10
config vlan default add forbidden 1-10
config vlan default delete 1-10

Тестовый клиент подключен в 1 порт 3200, но по логу dhcp сервера я вижу что релеить начинает не только первый 3200 свич, но и второй 3526, находящийся в том же vlan.
Как можно отключить на магистральных портах релей dhcp ? Или может быть это можно решить разносом клиентских портов в отдельные vlan на коммутаторах?
Как это выглядит со стороны dhcp сервера:
