add more accounting attributes in the packet from NAS

[admin_2]

I want to add more attributes in accounting packet than what cisco 2509 NAS sends by default to the radius server. Can anyone show me the way how to add more accounting attributes like Acct-SessionTime and more in the accounting packet that is sent by NAS to radius.
