SYSTEMS AFFECTED

    ACC/Ericsson Tigris

PROBLEM

    John  Edwards  found  following.   The  Tigris  is  a high-density
    router/remote-access platform,  currently a  product of  Ericsson,
    more information on it can be found at:

        http://www.ericsson.com/datacom/products/wan_access/tigris/index.shtml

    There appears to be a bug in the Tigris operating system  software
    that  causes  Radius  accounting  to  fail  under  certain   login
    conditions.   This  allows  a  user  to  log  on  to the system as
    normal, but Radius accounting data is not sent for either Stop  or
    Start records,  so no  call is  logged.   No alarms are triggered,
    and the problem occurs  even when multiple accounting  servers are
    configured for an access partition.

    Those who bill their customers based on Radius Accounting data may
    be affected.   It will  also mean  that logs  will not  contain IP
    address information for a  user, or may not  have a record of  the
    user's access at all.   This occurs when a  user dials the  Tigris
    and fails authentication.  Part of the PPP Authentication  routine
    allows a  user to  retry their  login without  needing to redial a
    connection if their PPP software supports it (this is  implemented
    in Windows 98).  After a  user fails their login then retries  and
    successfully connects,  the Tigris  may not  send Accounting  data
    for that user.

SOLUTION

    The problem appears to be fixed in 11.5.4.22 software release.
