AAA authentication with RADIUS

Hi,
aaa authentication login user-list group radius local
radius-server host 10.1.1.3 auth-port 1645 acct-port 1646 key xxxx
radius-server deadtime 10
If i add more radius-server host such as
radius-server host 10.1.1.4 auth-port 1645 acct-port 1646 key xxxx
1. Server 10.1.1.4 will be backup for server 10.1.1.3?
2. Can i configure to be radius group?
Thanks

Hi,
you can try the following:
Router(config)# aaa group server radius
Router(config-sg radius)# server 10.1.1.3
Router(config-sg radius)# server 10.1.1.4
when you configure the aaa group like this 10.1.1.3 will be primary and 10.1.1.4 is secondary
Hope this helps.
Regards,
Anisha

  • AAA Authorization with RADIUS and RSA SecurID Authentication Manager

    Hi there.
    I am in the process of implementing a new RSA SecurID deployment, and unfortunately the bulk of the IOS devices here do not support native SecurID (SDI) protocol. With the older RSA SecurID deployment version, it supported TACACS running on the system, now in 8.x it does not.  Myself, along with RSA Support, are having problems getting TACACS working correctly with the new RSA Deployment, so the idea turned to possibly just using RADIUS
    I have setup the RADIUS server-host, and configured the AAA authentication and authorization commands as follows:
    #aaa new-model
    #radius-server host 1.1.1.1 timeout 10 retransmit 3 key cisco123!
    #aaa authentication login default group radius enable
    #aaa authorization exec default group radius local
    I have also tried
    #aaa authorization exec default group radius if-authenticated local
    I can successfully authenticate via SSH to User Mode using my SecurID passcode -- however, when I go to enter Priv Exec mode, it wont take the SecurID passcode - I just get an "access denied"
    I've ran tcpdump on the RSA Primary Instance, looking for 1645/1646 traffic, and I dont get anything
    I've turned on RADIUS debugging on the IOS device, and I dont get anything either
    I did see this disclaimer in a Cisco doc: "The RADIUS method does not work on a per-username basis."  -- not sure if this is related to my issue?
    I'm beginning to wonder if IOS/AAA cant pass authorization-exec process to RSA SecurID

    I don't have a solution, but can confirm I have the same problem and am also trying to find a solution.
    I see no data sent to the RSA server when using the wireless AP. With other equipment on the same ACS, I do see the attempts going to the RSA server.
    The first reply doesn't seem to apply to me, since it's not sending a request from the ACS machine to the RSA machine.

  • Cisco AAA authentication with windows radius server

    Cisco - Windows Radius problems
    I need to created a limited access group through radius that I can have new network analysts log into
    and not be able to commit changes or get into global config.
    Here are my current radius settings
    aaa new-model
    aaa group server radius IAS
     server name something.corp
    aaa authentication login USERS local group IAS
    aaa authorization exec USERS local group IAS
    radius server something.corp
     address ipv4 1.1.1.1 auth-port 1812 acct-port 1813
     key mypassword
    line vty 0 4
     access-class 1 in
     exec-timeout 0 0
     authorization exec USERS
     logging synchronous
     login authentication USERS
     transport input ssh
    When I log in to the switch, the radius server is passing the corrrect attriubute
    ***Jan 21 13:59:51.897: RADIUS:   Cisco AVpair       [1]   18  "shell:priv-lvl=7"
    The switch is accepting it and putting you in the correct priv level.
    ***Radius-Test#sh priv
       Current privilege level is 7
    I am not sure why it logs you in with the prompt for  privileged EXEC mode when
    you are in priv level 7. This shows that even though it looks like your in priv exec
    mode, you are not.
    ***Radius-Test#sh run
                    ^
       % Invalid input detected at '^' marker.
       Radius-Test#
    Now this is where I am very lost.
    I am in priv level 7, but as soon as I use the enable command It moves me up to 15, and that gives me access to
    global config mode.
    ***Radius-Test#enable
       Radius-Test#
    Debug log -
    Jan 21 14:06:28.689: AAA/MEMORY: free_user (0x2B46E268) user='reynni10'
    ruser='NULL' port='tty390' rem_addr='10.100.158.83' authen_type=ASCII service=ENABLE priv=15 vrf= (id=0)
    Now it doesnt matter that I was given priv level 7 by radius because 'enable' put me into priv 15
    ***Radius-Test#sh priv
       Current privilege level is 15
       Radius-Test#
    I have tried to set
    ***privilege exec level 15 enable
    It works and I am no longer able to use 'enable' when I am at prv level 7, but I also cannot get the commands they will need to work.
    Even if I try to do
    ***privilege exec level 7 show running-config (or other variations)
    It will allow you to type sh run without errors, but it doest actually run the command.
    What am I doing wrong?
    I also want to get PKI working with radius.

    I can run a test on my radius system, will report back accordingly, as it's a different server than where I am currently located.
    Troubleshooting, have you deleted the certificate/network profile on the devices and started from scratch?

    SSID: DTS-Group using authentication EAP with RADIUS and it working great (Authentication Type from Aironet to RADIUS is PEAP)
    SSID:L6-Webauthen-test using web-auth and i had try to compare with RADIUS but ROOT CAUSE is AUTHENTICATION TYPE from Aironet to RADIUS default is PAP. (Reason Code : 66)
    => I had trying to find how to change Authentication Type of Web-Auth on Cisco Aironet from PAP to PEAP or sometime like that for combine with RADIUS.
    Any idea or recommend for me ?
    Thanks for see my case  

    Hi Dhiresh Yadav,
    Many thanks for your reply me,
    I will explain again for clear my problems.
    At this case, i had setup complete SSID DTS-Group use authentication with security as PEAP combine Radius Server running on Window 2008.
    I had login SSID by Account create in AD =>  It's work okay with me. Done
    Problems occurs when i try to use Web-authentication on Vlan45 With SSID :
    dot11 ssid L6-Webauthen-test
       vlan 45
       web-auth
       authentication open 
       dot1x eap profile DTSGROUP
       mbssid guest-mode
    After configured on Aironet and Window Radius , i had try to login with Account create in AD by WebBrowser but it Fail ( i have see mini popup said: Authentication Fail" . So i go to Radius Server and search log on EventViewer.
    This is My Logfile on Radius Win 2008 :

    Im  think ROOT CAUSE is :
    PAP is the default authentication type for web-auth users on Aironet 2702i, so it can't combine with Radius Window 2008 because they just support PEAP (CHAPv1,CHAPv2....) => Please give me a tip how to change Authentication Type from PAP to PEAP for Web Authentication on Aironet

  • Mac adress authentication with Radius

    Hello all
    we have an WiFi architecture based on two Radius servers (ACS 3.2)
    We make a Mac adress authentication with WEP on these Radius servers. Ours Wirelless cards are Proxim Orinoco. When we used the user and the passord identified by the mac adress manualy that works.
    But, the authentication by Mac adress with the wireless card don't work. The log on the radius servers are "CS PASSWORD INVALID".
    Ideas ?
    Regards

    First ensure the password on the access point and the authentication server is the same. I have had this trouble getting authenitcated with ACS for admin authentication. Installing it on another machine made it work. So try uninstalling ACS completely using the recovery CD and reinstall it to check if this works.

    This is the radius users file. It's a simple file for test.
    DEFAULT Auth-Type := Accept
            Tunnel-Type = VLAN,
            Tunnel-Medium-Type = IEEE-802,
            Tunnel-Private-Group-Id = 666
    I am attaching a screenshot of the Radius reply sent by the server.
    I also tried setting "copy_request_to_tunnel = yes" and "use_tunneled_reply = yes" as found in another post, no success.
    It may be that the tag is missing in the Radius reply? If yes, how do I add it?
    Any ideas?
    Thanks.
    Update Dec 11: I tried with FW 1.4.0, and using the same config the switch doesn't perform any Radius requests at all anymore.

    I was wrong when I said that 1.4.0 wouldn't work at all. I simply had a device connected which didn't produce much traffic. My bad.
    So 1.4.0 works as far as the auth is concerned, but no improvement as far as dynamic VLAN is concerned. So there is no improvement over 1.3.7, or there is a config issue.
    I have opened SR 633001533 although the last appointment for WebEx went by without anyone getting back to me. I'll try again on Monday.
    Feel free to get back to me if you need anything to make experiments. I'll keep this thread updated too.

    That output is from WLC 5508 version 7.0.235
    What is strange, that user was able to authenticate from other before refresh WLC 4402 ver 4.2.207. I cannot change WLC because of AP which cannot run old version.
    this is output from working client connection from old WLC

    I know there is different Policy Name used, but my question is why it is not using the same as on old WLC when configuration is same.
    Is there any way I can force users to use different policy from WLC or AP configuration or is this solely configuration of Radius?
    Is it maybe problem of version 7.0.235?
    Any toughts would be much appriciated.

    Scott,
    You are probably right. The condition that is checked for the first policy name (we have 2) is to match
    NAS-Port-Type = Wireless - IEEE 802.11, and this is basically used to differentiate guests from other company users.
    as you can see from the logs the one that is working correctly is not sending NAS-Port-Type. The question is why.
    As I said before.
    WLC 5508 ver. 7.0.235 is sending NAS-Port-Type
    WLC 4402 ver. 4.2.207 is not.
    The same user was working OK on 4402 WLC and after refresh and associating APs to 5508 it all broke, so client did not changed anything on adapter.

  • Issue with authentication with RADIUS when using VPN

    Our customer has a problem with auhtentication against Radius vhen he is using VPN or SSL VPN. Authentication on SSH or TELNET via RADIUS is working fine . When I configure on VPN (and SSL VPN) authentication against the local database, everything is working fine and tunnel is established.
    In attachement is running-config of customer's gateway and capture file of communication between RADIUS server and gateway (radius access request starting at 85th line).
    I found in this file at AVP attributes that the gateway is sending ipsec profile name (in this case "VPN") instead of username.

    SSLVPN is configured to use the local database of usernames only in this config. It is not configured to use RADIUS.

  • IEEE 802.1x Authentication with RADIUS failed

    Hello guys,
    I've a little strange Situation.
    If user start his Computer (Windows 7 enterprise) and computer is connected via LAN it works fine.
    If user start his Computer (Windows 7 enterprise) and computer is connected via WLAN it works also fine.
    But if user start his Computer (Windows 7 enterprise) that is connected via LAN it is not more possible to connect to WLAN (parallel). I've implemented an IEEE 802.1 RADIUS authenticiation.
    It does not work with this special user account. I've tested it already successful with couple other accounts.
    Does someone has experience with such Situation?
    Regards
    Rodik

    It does not work with this special user account. I've tested it already successful with couple other accounts.
    Hi,
    Did you mean that this problem just occures to the single User Account but others works fine at same computer, isn't it?
    When it connect Wlan failed, is there any error message? Have you tried to reinstall the WLan device driver for test?
    it would be better to provide more details about the Wlan connect failed.

  • Cisco AAA and Free Radius enable secret failure

    Hi,
    I am currently testing aaa authentication with free radius.
    I can authenticate users through the radius server, however i cannot authenticate the enable secret.
    Here is the router configurations
    aaa new-model
       aaa authentication login default group radius local
       aaa authentication login localauth local
       aaa authentication ppp default if-needed group radius local
       aaa authentication enable default group radius enable
       aaa authorization exec default group radius local
       aaa authorization network default group radius local
       aaa accounting delay-start

       aaa accounting network default start-stop group radius
    radius-server host 192.168.0.135 auth-port 1812 acct-port 1813 key cisco
    I have created a user for the enable secret as such:
    $enable15$   Auth-Type := local
            Service-Type = NAS-Prompt-User
    The router cannot authenticate when logging for priviliged mode. I cannot find any log on the radius server as well.
    PLease help.

    It should be $enab15$ as the user that IOS sends to the radius server.

  • Radius authentication with ISE - wrong IP address

    Hello,
    We are using ISE for radius authentication.  I have setup a new Cisco switch stack at one of our locations and setup the network device in ISE.  Unfortunately, when trying to authenticate, the ISE logs show a failure of "Could not locate Network Device or AAA Client" The reason for this failure is the log shows it's coming from the wrong IP address.  The IP address of the switch is 10.xxx.aaa.241, but the logs show it is 10.xxx.aaa.243.  I have removed and re-added the radius configs on both ISE and the switch, but it still comes in as .243.  There is another switch stack at that location (same model, IOS etc), that works properly.
    The radius config on the switch:
    aaa new-model
    aaa authentication login default local
    aaa authentication login Comm group radius local
    aaa authentication enable default enable
    aaa authorization exec default group radius if-authenticated

    As a test, I setup a device using the .243 address.  While ISE claims it authenticates, it really doesn't.  I have to use my local account to access the device.
    Any advice on how to resolve this issue would be appreciated.  Please let me know if more information is needed.

    Well from the debug I would say there may be an issue with the addressing of the radius server on the switch.
    radius-server host 10.xxx.xxx.xxx key******** <--- Make sure this address and Key matches what you have in ISE PSN and that switch. Watch for spaces in your key at the begining or end of the string.
    What interface should your switch be sending the radius request?
    ip radius source-interface VlanXXX vrf default
    Here is what my debug looks like when it is working correctly.

    This is a default template I use for all my devices routers or switches hope it helps. I have two PSN's that is why we have two radius-server host commands..

    aaa authentication login con group radius local enable
    aaa authentication dot1x default group radius
    aaa authorization network default group radius 
    aaa accounting system default start-stop group radius

    radius-server host xxx.xxx.xxx.xxx auth-port 1645 acct-port 1646 key *********
    radius-server host xxx.xxx.xxx.xxx auth-port 1645 acct-port 1646 key *********
    radius-server vsa send accounting
    radius-server vsa send authentication
    You can use this in the switch to test radius

  • Using CHAP with RADIUS authentication

    Hi
    I have configured a Cisco 877 router to send RADIUS requests when a user logs in to the console (Line Console or Line VTY) using the following config:
    aaa new-model
    aaa authentication login default group radius
    aaa authentication ppp default group radius
    radius-server host 10.0.0.1 auth-port 1812 acct-port 1812 key mysharedkey
    When I log the RADIUS packets I see that the Cisco router is sending the initial AccessRequest using PAP.
    How can I configure the router to send it's inial AccessRequest packet using CHAP?
    Apologies if this has already been discussed, I have searched high and low for an answer.
    Thanks in advance.
    John

    Hi Carlos
    Thanks for your response. I understand what it says in the RFC:
    The NAS then sends an Access-Request
       packet to the RADIUS server with the CHAP username as the User-Name
       and with the CHAP ID and CHAP response as the CHAP-Password
       (Attribute 3).
    But, by default the NAS (in this case the Cisco 877 router) is sending a RADIUS packet with a PAP encoded password by default. As the NAS initiates the AccessRequest I need to configure it to send the correct attributes for the CHAP challenge. This is configured on the RADIUS server so it knows the NAS is going to send CHAP but the NAS initiates the request and I guess needs to be configured to do so.
    Is this possible on a Cisco 877? How?
    Thanks
    John

  • Radius authentication with MSCHAP

    Hi,
    I have a few 2960 and 3650 switches in my network. I have the aaa authentication login configured for RADIUS but it is only using PAP which is unencrypted.
    The 2960 switches are running version 15.2 and the 3650 are on 3.02. The RADIUS server I am using is Microsoft NPS which can do other methods of encryption.
    Is it possible to do mschap or any other type of encryption with the switches to authenticate management access?
    Regards,
    Waqas

    This sample configuration shows how to set up a remote access VPN connection between a Cisco VPN Client (4.x for Windows) and the PIX 500 Series Security Appliance 7.x using a Cisco Secure Access Control Server (ACS version 3.2) for extended authentication (Xauth).

  • Cisco PI 1.3 - Internal Server Error with RADIUS-authentication

    Hi,
    I have a problem with a Cisco Prime Infrastructure 1.3 (Appliance, fully patched) that I'm trying to authenticate against a Radiator RADIUS-server.
    From the RADIUS-server's point of view it looks fine, but I just get an HTTP Status 500 internal error (see attached image) when trying to log in.
    I'm not the one managing the RADIUS-server but I got the following debug sent from them:

    Does anyone have any idea on what the the problem is, or some tips on how to troubleshoot? (rebooting and ncs stop/start has no impact on the issue)
    //Charlie

    I ran into a similar issue this morning in my lab.  After I issued ncs status - the database service came back as not running.  I stop/started the Prime services and it came up.  Once all the services were running my WLC imported with no issues.  I also deployed another server for another lab and it had issues with the clocking being out of sync.
