(RADIATOR) tigris and Accounting-Request

Mon Mar 31 07:53:33 CST 2003

Hi,
I got strage problem with radiator 3.5 and tigris with 12.3.1.15 firmware.
Tigris is sending me Accounting-Requests with Nas-Reload many times with
the same acct-session-id, and after that radiator wants to delete all
sessions which belongs to this NAS.
I dont know if its tigris bug or feature.
After every packet from NAS radiator sending response:
------

Here my config:

<Client aaa.bbb.ccc.ddd>
        NasType TigrisNew
        Secret abcdabcd
</Client>
and Handler:

<AuthBy INTERNAL>
  Identifier AccountingResponse
  AcctResult ACCEPT
</AuthBy>

   # define Handlers
<Handler Request-Type = Accounting-Request>
  AuthBy AccountingResponse
        AcctLogFileName ./detail
</Handler>

I got 12 tigrises and all of them are doing the same.
And not only NAS-Reloads/resets, but Acc-Acct-On-Off-Reason = Enabled and
so.
I've checked freeradius and it looks that he got somenthing that
recognizes packets with same session-id and somehow knows that
NAS-reloaded many seconds ago and he doing nothing. Or if packets is seen
first time, updating session database.
I've informed ericsson too so i am waiting for additional info.
Best Regards
