I have a Cisco router, configured to use AAA with a ASC server. TACAS access works fine for vty access, i.e it gets me to the enable mode, but when I attempt to log in via https://www.experts-exchange.com/questions/26810912/Error-in-Authentication-cisco-console-error.html the console, I get the %error in Authentication error message! There's no local username and password configured but there is an enable secret!

What is the error message you get when trying to login? Does it just prompt for password again? –Joseph Mar 21 '10 at 11:55 The switch accepts the login command in con term mode but after exiting to normal mode it doesn't get display when a sh run is executed –3D1L Mar 25 '10 at 16:42 try doing a debug aaa ... command –MikeyB Jul 28 '11 at 0:05 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote Seems correct to me. From Cisco site: Example 1: Exec Access using Radius then
the console/VTY line and privilege exec boundaries, through the use of static, locally defined passwords. For example: enable secret 5 $1$J19J$Q2jB2AM64H0U001nHStLW1 ! no aaa new-model ! line con 0 password 7 0532091A0C595D1D3B00351D190900 login line vty 0 15 password 7 152B0419293F38300A36172D010212 login While easily implemented, this approach is far from ideal for a production network. For much more robust and easily managed authentication schemes, IOS supports the Authentication, Authorization, and Accounting (AAA) model, using the RADIUS or TACACS+ protocols to centralize these functions on dedicated AAA servers. This article will look at deploying a typical IOS router AAA configuration which must meet two requirements: All users logging into the router must authenticate with a username and password to one of two redundant TACACS+ servers. Users must be able to log in using a backup local user account stored on the router only if neither TACACS+ server is reachable. This article assumes that all back-end AAA server configuration has been completed and is working. Configuring AAA on IOS for general administrative access entails four basic steps: Enable the "new model" of AAA. Configure the server(s) to be used for AAA (e.g. TACACS+ servers). Define authentication and authorization method lists. Enforce AAA authentication on the relevant lines (e.g. console and VTY lines). Step 0: Create a backup user account Although not technically a part of AAA configuration, we want to ensure a backup user account exists in the event the AAA servers become unreachable, so that we can still log in to the router. Router(config)# username BackupAdmin privilege 15 secret MySecretPassword Step 1: Enabling AAA The new AAA model of authentication is enabled with a single command, which unlocks all other aaa commands on the command line interface. Note that this command will break non-AAA line and enable passwords. Router(config)# aaa new-model Step 2: Configuring the TACACS+ servers Next we need to configure the addresses of the AAA servers we want to use. This example shows the configuration of TACACS+ servers, but the concept applies to RADIUS servers as well. There are two approaches to configuring TACACS+ servers. In the first, servers are specified in global configuration mode using the command tacacs-server to specify an IP address and shared secret key for each server: Router(config)# tacacs-server host 192.168.1.3 key MySecretKey1 Router(config)# tacacs-server host 192.168
