Hello, Here a access-request packet from a Cisco Router (2621) : NAS-IP-Address = "IP_NAS" NAS-Port = 66 NAS-Port-Type = Virtual User-Name = "MyUserLogin" Calling-Station-Id = "IP NAS" User-Password = "ry\My\Pass/Wo\rd\Hash\Not\Plain\Text`" Why is my password not in plain text ? With other cisco devices (Switch 2960 for example), the User-Password is in plain text.. If I receive a hashed password, the authentication doesn't work.. My AAA configuration : aaa new-model aaa authentication login default group radius line aaa authentication login console line aaa authorization exec default group radius none aaa authorization network default group radius aaa accounting exec default start-stop group radius aaa accounting connection default start-stop group radius What can I do ? Thanks for your help ! Nicos.
