Configuring aaa (authorization and accounting method)

For Authorization method list we will use custom list (not default one)

    Router(config)# aaa authorization command 1 TAC1 group tacacs+ local

   Router(config)# aaa authorization command 2 TAC2 group tacacs+ local

For Accounting method list

   Router(config)# aaa accounting command 1 TAC-ACT1 start-stop group tacacs+

Router(config)# aaa accounting command 2 TAC-ACT2 start-stop group tacacs+

Apply Authorization and Accounting to line vty


   Router(config)# line vty 0 4
   Router(config-line)# authorization commands 1 TAC1
   Router(config-line)# authorization commands 2 TAC2
   Router(config-line)# accounting commands 1 TAC-ACT1 
   Router(config-line)# accounting commands 2 TAC-ACT2
