Accton Edge-Core ES-3526XA
Цель статьи - описатьпроцедуру тестирования коммутатора Accton Edge-Core ES-3526XA. Планируется как замена Dlink DES-3526.
Загрузка
Наблюдаю загрузку (9600 8N1) с консоли. По первому впечатлению - не похож ни на один другой коммутатор.

Настройка
Не смотря на то что CLI вцелом cisco-like, это пожалуй самый неудобный в нстройке коммутатор из тех с которыми мне приходилось иметь дело.
DHCP Relay
Настройка коммутатора
Настройка достаточно простоа и вцелом аналогична другим коммутаторам (AT-8000S, Lucent LS-62..., DES- ...)
ip dhcp relay information option ip dhcp relay information option remote-id ip-address ip dhcp relay information policy replace IP DHCP relay server 172.16.251.1
Однако, отмечу что в пакете в качестве Remote-ID содержиться не ip а какой-то мусор. На данный момент у меня нет ответа от поставщика как расшифровать remote-id.

Padding
Первое впечатление, что формат Circuit ID анлогичен Dlink DES-3526 и другим коммутаторам (Если есть стандарт то хорошо бы найти докумнтацию)
Конфиг сервера аналогичен.
Простой пример:
class "port-1"
{
match if(
binary-to-ascii(10, 16, "", substring(option agent.circuit-id, 4, 2)) = "1"
);
}
Для логов использую следующюю конструкцию:
if exists agent.circuit-id {
log ( info, concat( "Lease for ", binary-to-ascii (10, 8, ".", leased-address), " is connected to interface ",
binary-to-ascii (10, 8, "/", suffix ( option agent.circuit-id, 2)), " , VLAN ",
binary-to-ascii (10, 16, "", substring( option agent.circuit-id, 2, 2)), " on switch ",
binary-to-ascii(16, 8, ":", substring( option agent.remote-id, 2, 6))));
log ( info, concat( "Lease for ", binary-to-ascii (10, 8, ".", leased-address),
"<>raw option-82 info is CID: ", binary-to-ascii (10, 8, ".", option agent.circuit-id), " AID: ",
binary-to-ascii(16, 8, ".", option agent.remote-i
В логах наблюдаю успешную выдачу IP

DHCP Snooping
При настройке DHCP Snopping мне удалось вызвать зависание коммутатора.
Пробую настроить согласно инструкции Монблана
