Kindly note that i implmented aaa new-model command on my switch with enabling to dot1.x on its port .
i created user name and password and the following autherization command :
aaa authorization exec default local none
aaa authorization commands 15 default local none
but if any one type telnet command to this switch IP with any user-name other than i put in the switch he get access to user mode on the switch without asking him for this user password .
the question is How can i stop this ?
