(RADIATOR) New Cisco SNMP query

[Hugh Irvine]

Hello again Vangelis -

BTW - here is an excellent overview of the Session MIB:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/ 
121newft/121t/121t3/dt_asmib.htm

Note that the "aaa session-mib disconnect" is only needed if you are  
going to enable disconnection of sessions via SNMP.

Thanks again.

regards

Hugh

NB: have you included a copy of your configuration file (no secrets),
together with a trace 4 debug showing what is happening?
