Не поднимается сессия ISG - initiator dhcp и ip subscriber routed

Здравствуйте.

Помогите.

Не поднимается ISG сессия:

policy-map type control isg
class type control always event session-restart
 10 authorize aaa list ipoe password cisco identifier circuit-id plus remote-id
 20 set-timer UNAUTH-TIMER 1
!
class type control always event session-start
 10 authorize aaa list ipoe password cisco identifier circuit-id plus remote-id
 20 set-timer UNAUTH-TIMER 1
!
!

interface TenGigabitEthernet0/0/0.1
service-policy type control isg
  ip subscriber routed
    initiator dhcp

При этом "unclassified ip-address" при "authorize aaa list ipoe password cisco identifier source-ip-address" успешно поднимается при любом ответов от радиуса (не успешные - unauthen).

Запрос на радиус идет с circuit-id:remote-id в поле User-Name... Но сессии на циске не вижу.... Что может быть?

Дебаг включали?

А не пробовали

ip subscriber connected или l2-connected (не помню дословно) и initiator dhcp?

авторизовать - авторизовали, а где сервис? service local в старт-рестарт допишите для начала. если поднимется - дебажьте навешивание сервисов с радиуса, либо оставляйте как есть

l2-connected работает... Но она не подходит т.к. за интерфейсом l3 сеть за которой находиться множество коммутаторов посылающих opt82 на циску в dhcp релай запросах.

Сервисы убрал пока, т.к. как-раз сессия и не поднимается сервисы уже потом навешиваются...

Она не поднимается даже в процессе авторизации - отправки запросов на радиус.

Соответственно есть ли в схеме policy-map type control service local с существующим сервисом или нет, роли не играет... сессии не вижу...

Кстати смотрю адреса поднимаются в "show ip subscriber"

Но все они выглядят как

...
routed      0              down     172.17.4.40/32
routed      0              down     172.17.4.85/32
...

И помоему все таки адреса dhcp шные должны быть в show ip dhcp database/binding ?

Хм, такую схему мы не использовали. Одна из наших схем - клиенты L2 connected, initiator dhcp, ААА по circuit+remote. Вторая - L3 connected, identifier - source ip, адреса выдаются отдельным сервером, трафик которого через брас не ходит.

А циска точно умеет сочетание опции 82 и routed?
