Defining Accounting Methods for a WLAN
Service
Accounting tracks the activity of
wireless device users. There are two types of accounting available:
- Controller accounting —
Enables the controller to generate Call Data Records (CDRs), containing usage
information about each wireless session. CDR generation is enabled on a per VNS
basis. For more information on CDRs, refer to section Call Detail Records (CDRs).
- RADIUS accounting — Enables
the controller to generate an accounting request packet with an accounting start
record after successful login by the wireless device user, and an accounting
stop record based on session termination. The controller sends the accounting
requests to a remote RADIUS server.
Controller
accounting creates Call Data Records (CDRs). If RADIUS accounting is enabled, a
RADIUS accounting server needs to be specified.
To define accounting methods:
-
From the top menu, click
VNS.
-
In the left pane expand
the WLAN Services pane, then
click the WLAN (Wireless Local Area Network) Service you want to define
accounting methods for. The WLAN Services
configuration page is displayed.
-
Click the Auth & Acct tab.
-
Select an authentication
method under Mode or click Enable MAC-based
authentication.
The Enable RADIUS Accounting check box
displays.
-
In the Accounting column, select the
RADIUS server. For more information, see Selecting RADIUS Servers.
Note
When multiple RADIUS servers are configured for a
WLAN Service, Accounting packets are sent to the primary RADIUS server only.
The secondary servers are used as fail over when necessary. When upgrading
to v10.31.02, the previous behavior of sending Accounting packets to all
servers is maintained.
-
One a server is selected, click Configure.
-
The RADIUS Parameters dialog
is displayed.
The
configured values for the selected server are displayed in the table at the
top.
-
For NAS IP Address, accept the
default of “Use VNS IP address” or de-select the check box and type the IP
address of a Network Access Server (NAS).
-
For NAS Identifier, accept the
default of “Use VNS name” or type the Network Access Server (NAS) identifier.
The NAS identifier is a RADIUS attribute that identifies the server responsible
for passing information to designated RADIUS servers and then acting on the
response returned.
-
For Auth. type, select the
Protocol using the drop down list. Choices are PAP, CHAP, MS-CHAP, or
MS-CHAP2.
-
In the
Password box, type the
password that will be passed to RADIUS for wireless MAC authentication.
To
proofread your shared secret key, click Unmask. The password is
displayed.
-
Click OK.
-
To enable Controller
accounting, select Collect Accounting Information of
Wireless Controller.
-
To save your changes,
click Save.
