OPNsense Captive Portal Radius Accounting Attribute

[mindf]

Hi,

What are the radius attribute supported by OPNsense Captive Portal?
From https://docs.opnsense.org/manual/how-tos/accounting.html only mentioned 2 attributes

ATTRIBUTE       Daily-Session-Time      3000    integer
ATTRIBUTE       Max-Daily-Session       3001    integer

Any attribute similar to 'pfSense-Max-Total-Octets' available? or any documents available on this?

Thanks!
