Accounting problem with CISCO 5200

[Alexey K]

Hello!

I have CISCO 5200 with the following config:

aaa accounting delay-start
aaa accounting update periodic 5
aaa accounting network default start-stop radius

Also, I have freeradius server connected with SQL database.

Alive-packets (from cisco) don't include information about sent/received 
bytes (AcctInputOctects/AcctOutputOctets), however, the "Stop records" 
include such information.
So, is it possible to enable AcctInputOctects/AcctOutputOctets in the 
alive-packets from CISCO 5200? How?

Is it issue of CISCO IOS or radius server?

Sincerely Yours,
Axe Sky
