Hello,

Thank you Alan for give me direction.

Yes. I did.
Following packages installed on my server.

FreeRADIUS 2.1.4
Perl 5.8.9
p5-SNMP_Session-1.12
p5-Net-Telnet-3.03
MySQL-5.0.77

I decided to use SNMP_Session and BER modules.
When I'm executing checkrad by hand then I got following message.

# checkrad cisco 192.168.0.60 1645 tseveen 40
SNMP Error:
Received SNMP response with error code
  error status: noSuchName
  index 1 (OID: 1.3.6.1.4.1.9.2.9.2.1.18.1645)

checkrad: No SNMP answer from cisco.
checkrad:  not found!

I thought maybe OID is not compatible for my router c3825. is it ?
Can you please provide more information about NAS port and Session ID ?

Tseveen.
