Подключение абонентов по схеме "vlan-на-клиента", при этом используется оборудование D-Link - на уровне доступа свитчи DES-1228G, в ядре - DGS-3610-26G. Это шлюз ядра(DGS-3610-26G).

конфигурация шлюза 

user_rule.editor.class=bitel.billing.module.services.ipn.editor.vlan.CiscoVlanContactRuleEditor
gate_manager.class=bitel.billing.server.ipn.vlan.CiscoVlanGateWorker
