I am Anubhav ,i m new to TACACS+ server and trying to implement aaa authentication using Cisco TACACS+ Server for which i've decided following AAA commands and a fall back user user1 has been configured on router to be authenticated.
aaa authentication login default group tacacs+ local
aaa authentication login NO_AUTHEN none
aaa authorization config-commands
aaa authorization exec default group tacacs+ if-authenticated
aaa authorization exec NO_AUTHOR none
aaa authorization commands 1 default group tacacs+ if-authenticated
aaa authorization commands 1 NO_AUTHOR none
aaa authorization commands 15 default group tacacs+ if-authenticated
aaa authorization commands 15 NO_AUTHOR none
aaa authorization network serial none
aaa accounting exec default start-stop group tacacs+
aaa accounting commands 15 default stop-only group tacacs+
aaa session-id common:purpose of this line ?
