имеем 2 свича des 1210-28 и 3200-28

оба хочу завести на opt 82, 1210-28 заводится на ура с такими параметрами -

 

class "vlan2011_port1"
{
match if (
binary-to-ascii(10, 16, "",  substring(option agent.circuit-id, 4, 2)) = "1"
and substring(option agent.remote-id, 2, 15) = "10.0.104.11"
);

pool {
range 10.34.1.33;
allow members of "vlan2011_port1";
}

 

на этих рабьотает хорошо, а вот 3200-28 не пускает, мб у кого есть circuit-id remote-id Для них? или как расшифровать пакет?

я бы сам разобрался но в пакетах не шлется данных о opt 82

 

Running as user "root" and group "root". This could be dangerous.

имеем 2 свича des 1210-28 и 3200-28

оба хочу завести на opt 82, 1210-28 заводится на ура с такими параметрами -

 

class "vlan2011_port1"
{
match if (
binary-to-ascii(10, 16, "",  substring(option agent.circuit-id, 4, 2)) = "1"
and substring(option agent.remote-id, 2, 15) = "10.0.104.11"
);

pool {
range 10.34.1.33;
allow members of "vlan2011_port1";
}

 

У меня 3200-28 работает следующим образом:

class "10.0.1.23:p1" {
match if binary-to-ascii (10, 8, "", suffix( option agent.circuit-id, 1)) = "1"
and binary-to-ascii(10, 8, ".", packet(24, 4)) = "10.0.1.23";
}

pool {
range 192.168.12.5;
allow members of "10.0.1.23:p1";
}

Дело было в ДНК, не правильно настраивал на свиче, ISC-dhcp Работает на ура!
