•.work – This file is the active file that is being updated by the accounting
system. The file is closed and renamed with the .dat extension when it attains
its maximum size — 16 MB — or it has been open for the maximum allowed
duration — 12 hours. You can back up and copy .work file from the HiPath
Wireless Controller to a remote server.
•.dat – This file is the inactive file that contains the archived account records.
You can back up and copy the .dat file from the HiPath Wireless Controller to
a remote server.
Note: The CDR directory on the HiPath Wireless Controller only has two files —
a .work file and a .dat file. When the .work file attains its maximum size of 16
MB, or it has been open for 12 hours, it is saved as a .dat file. This new .dat file
overwrites the existing .dat file. If you want to copy the existing .dat file, you must
do so before it is overwritten by the new .dat file.
11.3.3 CDR file format
A CDR file contains a sequence of CDR records. The file is a standard ASCII text
file. Records are separated by a sequence of dashes followed by a line break.
The individual fields of a record are reported one per line, in “field=value’ format.
The following table describes the records that are displayed in a CDR file.
Note: Most of the CDR records are typical RADIUS server attributes. For more
information, refer to the user manual of your RADIUS server.
