Here's an example of an authentication method that will be applied only to an interface: Router(config)# aaa authentication ppp default group radius group tacacs+ local Router(config)# aaa authentication ppp apple group radius group tacacs+ local none Router(config)# interface async 3 Router (config-if)# ppp authentication chap apple You would create a method list and then apply it to the interfaces. Perhaps you wanted to apply a method list only to a particular interface or set of interfaces. Router(config)# aaa authentication login default enable
Here is one example of how to configure login authentication using the enable password. To configure AAA, use the following statement in global configuration mode: Router(config)# aaa new-modelįrom this point, most admins start configuring AAA by setting up authentication. If the security server or user database responds by denying the user access, the authentication process and the user will get a denied user prompt.
It is important to note that Cisco IOS software attempts authentication with the next-listed authentication method only when there is no response from the previous method. Apply the method lists per line/ per interface.Define the method lists for authentication.Configure authentication, using RADIUS or TACACS+.How do you configure AAA in the Cisco IOS? AAA is what keeps your network secure by making sure only the right users are authenticated, that those users have access only to the right network resources, and that those users are logged as they go about their business. Why every network admin should care about AAAīesides passing certification tests like the Cisco CCNA Security, AAA is a critical piece of network infrastructure. For example, with accounting, you could get a log of when users logged in and when they logged out.
You can use accounting to see what users do once they are authenticated and authorized. It provides a way of collecting security information that you can use for billing, auditing, and reporting.
Authentication: Identifies users by login and password using challenge and response methodology before the user even gains access to the network.Here is what each of these are used for and why you should care: When it comes to network security, AAA is a requirement.
