Cisco ISG: учет траффика по сервисам

radacct

Посмотрев на Acct-пакеты, вижу много полей, которых нет в классической таблице radacct

нет места ни в таблице ни в запросе, вносящим данные.

Соответвенно, следует дополнить radacct нужными полями и исправить запросы.

Сервисы

Каждый сервис для которого планируется вести учет траффика должен иметь в своем описании следующие атрибуты: 

Cisco-AVpair += "subscriber:accounting-list=LIST-NAME"
Acct-Interim-Interval = 60

LIST-NAME - предварительно сконфигурирован на роутере.

В моем случае это 

Cisco-AVpair += "subscriber:accounting-list=ISG-AUTH-1"

!
aaa group server radius ISG-RADIUS
 server 172.16.30.144 auth-port 1812 acct-port 1813
!
...
!
aaa accounting update periodic 1 jitter maximum 0
aaa accounting network ISG-AUTH-1 start-stop group ISG-RADIUS
!

Acct-Interim-Interval не может быть менее 60 сек. (больше -может быть).


Соответвенно сервис (например) KH-IX приобретает вид 

KH-IX_5_MBIT    Password == "cisco"
                Cisco-AVPair += "ip:traffic-class=in access-group 194 priority 8",
                Cisco-AVPair += "ip:traffic-class=out access-group 194 priority 8",
                Cisco-AVpair += "subscriber:accounting-list=ISG-AUTH-1",
                Acct-Interim-Interval = 60,
                Cisco-Service-Info += "QU;5120000;2048000;D;5120000;2048000"
