Radius Accounting and AP1100

Question

Hello,
I have lots of AP1121G, that authenticating users on a radius server (Radiator).
I need to make accounting of octets in and out per user, but i have some problems with this.
In general, the accounting is working fine, but the APs dont send some attributes that i need (Acct-Input-Octets, Acct-Output-Octets), included in Accounting-Request (stop) Packets (http://www.cisco.com/en/US/products/hw/wireless/ps4570/products_configuration_guide_chapter09186a00802091b1.html).
Someone can help me to find the problem?
I have a theory, but i don't know if is right: This attributes can't be sent because the IP Address is assigned to clients by a third DHCP Server (router cisco) and not by the Radius server. Could be by this?
How can i solve the problem?
The Radius part of configuration of my APs:
aaa new-model
aaa authentication login default local
aaa authentication login eap_methods group radius
aaa authentication login mac_methods local
aaa authorization exec default local
aaa authorization network default group radius
aaa accounting send stop-record authentication failure
aaa accounting update periodic 5
aaa accounting auth-proxy default start-stop group radius
aaa accounting exec default start-stop group radius
aaa accounting network default start-stop group radius
aaa accounting connection default start-stop group radius
aaa accounting system default start-stop group radius
aaa accounting resource default start-stop group radius
aaa nas port extended
aaa session-id unique
ssid MySSID
vlan 150
authentication open eap eap_methods
accounting default
ip radius source-interface BVI1
radius-server host 172.1.0.1 auth-port 1812 acct-port 1813 key 7 xxxxxxxxxxxxxxxxxxxxx
radius-server authorization permit missing Service-Type
radius-server vsa send accounting
radius-server vsa send authentication
Thanks in advance!
Nuno.
