logging in bit or

Hi, Is there any way to change the following thing fron octects to bytes or bits? for example Acct-Input-Bytes/Bits or Acct-Output-Bytes/Bits Acct-Session-Time = 58392 Acct-Input-Octets = 101147 Acct-Output-Octets = 136624 Acct-Input-Packets = 7723 Acct-Output-Packets = 8367 Where should I configure in BRAS or in Freeradius? If i want information about uplink and downlink bit/Bytes how do i get this information logged in radius log file. Who will send this information to Freerdius BRAS? BR Ganesh
