RADIUS server for authentication

Hello

I want to configure the radius server, so whenever someone tries to connect to a cisco (Telnet) switch, I want the radius to authenicate them server. Is this possible?

Yes it is possible as long as you configure your switches to authenticate to the Radius server. To achieve this, you must use a feature called AAA. This feature is compatible with the protocols such as Radius, GANYMEDE +, to name a few. The following link will give you an idea on how to set it up on switches IOS based specifically on the 3550:

http://www.Cisco.com/en/us/partner/products/hw/switches/ps646/products_configuration_guide_chapter09186a00801a6b15.html

Make sure that apply you the authentication list to the vty lines to ensure that telnet access is authenticated with the radius server. FOT based CatOS switches than the following link will be useful:

    Hello

    A 3850 catalyst switch has VLAN 20 (10.18.4.32/29) defined on it, which has a 10.18.4.38 gateway:

    D01-01-BWY #show ip short int vlan 20
    Interface IP-Address OK? Method State Protocol

    Have you run wireshark on the server because the request to switch? If so you make sure that there is a response from the server? For Windows network POLICY Server (I've never tried Centos), you must ensure that the request is related to a policy which then authenticates, or denies access. Usually, it is a matter of such attributes and the seller.

    Regarding the configuration, it seems a bit out of the AAA. Try to remove the:

    line "aaa dot1x group service radius authentication" and this by using instead:

    "aaa dot1x default radius authentication group". After the dot1x word you are supposed to provide a list of the authentication or the default Word if you do not want to use a list.

  • How 2 Configure ACS 4.2 to delegate authentication to the radius server

    Hello

    We need run the following scenario:

    Cisco VPN client (or any connect, Cisco SSL VPN client)---> Cisco ASA 5520---> Cisco ACS 4.2---> CAT Authentication Server

    The CAT authentication server is a Radius server. It can receive Radius authentication requests and respond. It is used for strong authentication TFA WBS similar to RSA OTP tokens.

    The question is: how we set up the 4.2 ACS to delegate authentication request to another Radius server.

    Thnx

    Add the RSA server as an external database, configure the drop user profile or a group to authenticate on the new external database rather than ACS DB Local (or Windows DB).

    Easy as pie!

  • ISE - authentication radius AAA for n access

    Hello

    I have configured the switches to use the ISE as a Radius Server to authenticate with, on the ISE, I configured an authentication strategy

    for the 'DNA' using the devices 'Wired' group that points to the source of identity AD to authenticate.

    All testing switches access connection we found 2 results:

    1.A domain user can connect to the switch as expected.

    2. each domain user that exists in the source of advertising identity can connect, this is an undesirable result.

    So I will try to find a way to restrict access to the ENAD to only a specific group belonging to the announcement, for example the group/OU

    of the IT_department only.

    I did not, would appreciate any ideas on how to achieve this.

    Switching configurations:

    =================

    AAA new-model

    !

    AAA authentication login default local radius group

    !

    ISE authentication policy

    ==================

    !

    Policy name: DNA authentication

    Condition: ": a device Type equal to: all Types of devices #Wired.

    Authorized Protocol: default network access

    Use the identity source: AD1

    No problem is how to set up policies, don't forget to evaluate any useful comments when you are finished testing.

  • With the help of several radius for authentication servers

    Hello.

    I want to install a PPTP to my router and I wonder if it is possible to use windows multiple IAS servers on a Cisco router?

    The scenario is that I have more than one business using this PPTP connection and they all have their own advertising on their own VLAN, I would like the router to forward the authentication request containing the username and password for all IAS of Windows servers that I specify or go through them one at a time until it receives an awnser.

    Is this possible?

    Best regards Tommy Svensson

    Tommy,

    This is not possible because if a radius server receives a user name, it will be simple rejection the user and send this response to the Cisco router. The radius Protocol is not throw or send any message to warn the router that the user is not present in its database.

    I know that with ACS that if a username has been sent with a special domain can proxy communication on the acs server and the Cisco router based on the user name.

    I hope this helps.

  • switch 3750 EAPoL transmission RADIUS server

    I have a running version of the 3750 switch stack 12.2 (53) SE2 IPBASEK9-M. I have dot1x configured on the switch and a Windows 7 PC, connected with 802. 1 x configured on the interface. I see the EAPoL start message from the PC, but I do not see the packets from the switch to the RADIUS server RADIUS. I have a config simple dot1x just to try to make it work before adding additional features such as comments - vlan...

    Config and debug of attached file.

    I don't know if the configuration ip dhcp snooping and arp of inspection is cause a problem with that or not. I see the EAPoL packet received on the switch, as shown in the attachment of debugging, but I never see the RADIUS packet. I've defined both trust on the interface, but always the same result. I can't turn it off because there is a switch of production with a test interface.

    Any ideas?

    Thank you

    Mark

    I had the same problem and solved it is enough to configure the switch as authenticator instead of "supplicant". "Supplicant" means customer, "authenticator" means in fact the switch acts as an authenticator to pass through, it will forward the requests to the auth server, for example, host of RADIUS.

    Hello

    I send RADIUS of NHP NHP, another. I have already defined "External RADIUS servers".

    So, how can I use this external RADIUS server to process my application?

    Looking at the user guide, but did not find information on this parameter (for the rule after rule not simple)

    Cela if anyone use this, please suggest me.

    Thank you

    Mathias

    Please specify which version you are using. There were improvements to the functionality of the proxy in ISE 1.1.1

    This can be used as follows:

    -Define "External RADIUS server"

    -Set the "Sequence of RADIUS server. This allows you to define a sequence of proxies that will send queries to until you get an answer

    -In the authentication policy when the rules instead of the allowed protocols can select a "RADIUS server Sequence.

  • NPS Windows Help for authentication of aaa for Cisco router - is it safe?

    I am very confused about how all this works and was hoping someone could help me.

    I followed a bunch of tutorials online for authentication RADIUS of installation on a Cisco router and he did to a NPS Windows Server. Now I can ssh into the router my AD account.

    Now that I got it to work, I go to the settings to make sure everything is secure.

    On my router, the config is pretty simple:

    aaa new-modelaaa group server radius WINDOWS_NPSserver-private 123.123.123.123 auth-port 1812 acct-port 1813 key mykeyaaa authentication login default local group WINDOWS_NPS
    
    ip domain-name MyDomcrypto key generate rsa
    
    (under vty and console)# login authentication default
    On the NPS Windows:
    • I created a new RADIUS client for the router.
    • Created a secret shared and specified Cisco as the name of the seller.
    • Created a new strategy of network with my desired conditions.
    • And now the frame of the configuration of the network policy that worries me:
    
    
    So initially I thought my AD credentials were being sent over the wire in plain text, but I did a capture and saw this:
    
    
    
    How is my password being encrypted and how strong is the encryption?
    
    Another thing is how can I configure aaa authentication with mschapv2? The documentation I saw for mschapv2 uses the "ppp authentication ms-chap-v2" command, but I'm not using ppp I'm using aaa with a radius server.
     
    

    Hello

    RADIUS encrypts the password, but sends the username in clear. GANYMEDE encrypts the user name and password.

    You can find the encryption used by RADIUS in the RFC scheme:

    https://Tools.ietf.org/html/rfc2865#page-27

    MS-Chap-V2 is used for the authentication of users such as the remote access and vpn, not management switch
