AAA and vty authentication

If I had this configuration:

RouterA #show config

username password forum 0 A34@#

AAA new-model

Authentication login ENTER local AAA.

AAA TO_CONSOLE authentication group Ganymede + local

Line con 0

authentication of the connection TO_CONSOLE

VTU line 0-3

password class

authentication of connection TYPE

Depending on the configuration above, users that telnet to the router must be authenticated via the line labeled AAA "ENTER." This line indicates that the local user database should be used, so users who enter the 'forum' as username and "A34@#" as a password to access the router.

What will be the use of the password: 'class', do we need?

This password is known as the line password as it is configured on the command-line interface. In your configuration, it does not at all and can probably be removed.

This password is used as the password when you are not using "aaa new-model". This password is probably the surplus of the days before you used AAA for authentication on the device.

If you want you can add the line password to your line of aaa authentication:

local line AAA authentication login ENTER

... in this case, access telnet would use local user names and passwords, but if these are not available for some reason any (maybe because you forgot to create them or accidentally deleted) the device could fall back to using the line for authentication password. This is not really useful we use local mostly as a backup for a source of authentication network Ganymede + in the case where the Ganymede server + is inaccessible over the network, which is much more likely that a problem occurring with your local user accounts.

  • Go to AAA to local authentication on 100s of production network devices

    Hello

    I'm looking to migrate 100 s of local AAA authentication devices. I have the code I need to apply, but I can't think of a way how to automate this process.

    If I connect to a switch using the local username, I can then add the config of AAA in the global mode

    AAA TACACS_LOCAL authentication connection group local TACACS_SERVERS

    authorization AAA console

    AAA authorization config-commands

    TACACS_LOCAL AAA authorization exec group local TACACS_SERVERS

    AAA authorization commands 0 TACACS_LOCAL TACACS_SERVERS local group

    AAA authorization commands 1 TACACS_LOCAL TACACS_SERVERS local group

    Group orders 15 AAA authorization TACACS_SERVERS local TACACS_LOCAL

    Start-stop accounting exec TAC TACACS_SERVERS AAA group

    AAA commands 0 arrhythmic TAC accounting TACACS_SERVERS group

    orders accounting AAA 1 group of start-stop TAC TACACS_SERVERS

    AAA commands 15 arrhythmic TAC accounting TACACS_SERVERS group

    However, once I added the config for the line, authorization and then comes into play (as I am logged in as a local user) and rejects any order entered, I then need to re-login using an account of AAA and apply this code;

    line vty 0 4

    authorization controls TACACS_LOCAL 0

    authorization controls 1 TACACS_LOCAL

    authorization controls TACACS_LOCAL 15

    exec authorization TACACS_LOCAL

    accounting orders 0 TAC

    TAC controls 1 accountant

    TAC of 15 accounting commands

    accounting exec TAC

    authentication of the connection TACACS_LOCAL

    I wanted to know if someone came up with a way to apply the code in a single shot? I would ideally like to automate this process using Cisco works, however, I don't see apart from Add this code to the startup config and re-boot anyway...

    Thank you very much

    LMS generally uses TFTP to deploy the configuration of devices. If the user should not be a problem.

    Go to Configuration-> model-> Import Center

    You can import a configuration of your devices by selcting one. When the configuration is retrieved, you can remove the parts of the configuration, you don't have to and paste the aaa authentication in the window.

    then click Next,

    Here you can preselect the devices you want to deploy. and then click Next.

    If no configuration is displayed, click Next.

    type the required information in the fields. Click on finish

    I recommend to create a template for the removal of the configuration of the aaa, but be aware that when you type just no aaa new-model configuration is 100% removed, soon you type still aaa new-model you have the old configuration was merged with the new. You negotiate all your orders of aaa, followed an aaa new-model step. (This cost me about 2 hours to understand how to remove it).

    Next step is to deploy the config on a test device.

    Go to Configuration-> model Centre-> deploy

    Select your template, and then click Next

    Select your device-> click Next

    If you do not configure any settings click then

    You can add a few additional configurations if you want, click Next

    Plan your deployment, and then click on finish

    Search for problems during the deployment, if everything has worked you can connect the device with your credentials of Ganymede.

    If there are problems with your model, export it and open it with an editor xml of your choice and change the model, import it, and try again.

    I add an example of model

    Good luck

  • RADIUS and GANYMEDE + authentication

    We authenticate our systems through dot1x. I also need to be able to authenticate our Cisco admins using the same ACS server. I see how to configure a switch to make the two GANYMEDE + and RADIUS, but I do not see how implement GBA to allow a switch to use GANYMEDE + and RADIUS.

    Can someone give me a pointer?

    Thank you

    You need to put in place once the authentication on the switch.

    AAA authentication login default group local Ganymede

    Group AAA dot1x default authentication RADIUS

    AAA authorization exec default group Ganymede + authenticated if

    Group AAA authorization network default RADIUS

    Cisco RADIUS-server host 2.2.2.2 keys

    Cisco GANYMEDE-server host 2.2.2.2 keys

    The GBA, you must add the switch twice.

    ACS---> network configuration---> add aaa-clinet

    Host name switch1

    IP: 3.3.3.3

    With the help of authentic: RADIUS IETF

    Add another switch

    SWITCH2 host name

  • Switch of AAA and password Enable question

    I have a switch with a config to base thereon and created some 15 local user privilege.  I was copying the config of another switch and unfortunately did NOT know the secret to activate it but still added to the (stupid I know) configuration.  Opening a session on the switch after being in production was working fine, until I tried to configure AAA.  As the enable password I've referenced another similar switch for configuration of the AAA and I did this several times in the past and it works normally.

    However, this time AAA would work not for a reason any but everything was fine because the local user account.  Then I made a few other changes trying to solve the AAA and now when I login, it invited me to this password to enable a reason any?  The local user works get me in but for the non-privilege mode.   Can anyone shed some light on why this is happening?

    It would be difficult to provide information on why your config didn't work as expected without seeing the actual config :)

    So, it looks like you will need to perform a password recovery. You can follow the instructions in this link:

  • UNIQUE between Simple mode and open authentication possible OAM?

    Hello

    Our SSO OAM in 'Open' mode (WP, PM, AM, AAA and ID).

    I would like to configure an applications in SIMPLE mode between the access server and webgate. But still I'd like to preserve, single sign - on, when the user accesses the protected open OAM application.

    Is this possible? Thank you.

    Yes, possible. The transport application component security mode has no impact on the end user SSO.

    Technically, the mix of modes (simple and open) is not supported. If you have installed some AAA servers more in simple mode you can connect your webgate to those simple ones more and not the other (open mode) to avoid this problem.

    If you need to share the existing AAA servers you will need to bring the listening in BOTH modes. This used to work even if I have not tried with recent versions. The technique is to (re) configure the AAA servers in Simple mode and then pass the parameter mode back to open the profile of component in the directory (via the admin UI).

    Have you spent by the view configuration listed below parser example. Please check here

    View the authentication is performed by an external authentication via the new "cli-view-name" attribute server so you must use cisco-av-pair as cli-view-name = xxxx

    The AAA authentication only associates a single view to a user name given; in other words, display only a single name can be configured for a user to an authentication server.

    In case you still some problem, run debug Analyzer view and share it out, I'll try to help.

  • Problem IOS 15 and VTY ACL

    Dear community!

    We have recently installed a router C2951 running the version IOS 15.0 (1). However, we have a VTY ACL configuration problem. When trying to connect to the router via SSH, the ACL VTY has some matches on the SSH client's IP address, but the router refuses the SSH connection when the standard of the "VTY_ACL" called ACL is set on line vty (marked by red color). If no ACL VTY has assinged to the vty router line, the SSH connection is OK.

    The current configuration seems to be OK, see below:

    ...

    [(Il y a certaine configuration AAA, y compris TACACS + et enfin l'auth local à la fin de la liste de séquence).]

    ...

    line vty 0 4

  • How can I erase the active sessions and / or authenticated at a granular level?

    When I visit a Web site and I authenticate either via username or certificate / States PKI, identification and authentication information is stored somewhere. I want to know where that somewhere, so I can cancel these one at a time manually.

    I understand that I can go into the Options and clear browsing data - and Yes, this will accomplish the same sorta thing - however, it will kill ALL my sessions authenticated through ALL my tabs. I would like to know if there is a manual way where I can do BY the site, while it is not a such brute force method.

    Last note: I don't want to close all my tabs (Firefox completely quit). Nor do I want to go through the options to do. If I can be educated to know where is my session store location and authentication, then this will answer my question.

    I am an advanced user and have no problem working my way around my system to fit my needs, I don't know where to find this database store.

    It is likely not possible since it is to disconnect from the secret decoder ring (CSD) and the sending of a notification to close all http and ftp sessions (net: clear active connections).
