Your NAS needs to support interim accounting.
If it does already, it might be as simple as adding:
DEFAULT
Acct-Interim-Interval = 1800,
Fall-Through = yes
...to the "users" file; modify as appropriate of course for your config.
I have added the lines above to my "users" file, replacing 1800 with a
value of 20. However, the updates do not occur every 20 minutes. Do I
also need to enable something on my NAS (Cisco WiSMs) to allow it to
provide accounting on demand?
Not sure. It definitely works; we have it working here.
Are you getting *any* accounting from the WISM? You'll need:
radius acct add $server_id $server 1813 ascii secret
wlan radius_server acct add $wlan_id $server_id
I notice we've got:
wlan session-timeout $wlan_id 1800
...statements in our config, but I'm not an expert on the WISMs so I
don't know if that's required.
I did also try to edit the config on my WiSMs to push the accounting
every 20 minutes but was unable to get that to work. The guy who
primarily looks after the WiSMs is away at the moment.
How is interim accounting normally done? I don't mind if the accounting
is pushed or pulled, whatever works.
Accounting is always pushed from the NAS to the Radius server.
Thanks,
Jonathan
