NAP 802.1x Enforcement – Switches we’ve tested w/NAP

Všechny reakce

  • Hi Jeff,

    Thanks to publish the list of the swtches which can support NAP.

    I can understand that all the switches can supposrt NAP for wired connection.

    Suppose, If i would like to use wireless connection (Putting a wireless Acsess Point between switch and Vista client).

    Do Cisco switch 3560 support for NAP for when packet arrived from wireless Accecc point.

    My idea is....

    Kindly teach me on this scenario.

  • Yes that will work with VLAN tagging. See my blog for an indication of how this is done with a Cisco switch.

     

    Go to blogs.technet.com/mkleef and click the category "Blogcasts by me". I havent included the wireless bits but the base switch config is what youll need first.

  • Hello ,

     

    If you want to use NAP over Wireless network. You may need a wireless LAN Controller. Because Wireless Access Points cannot support Dynamic VLAN ing.

     

    Regards.

  •  Hi,

    I've search all throuch the internet, but can't find any valuable information about which 802.1x modes NAP exactly supports.
    There are several different 802.1x possibility, like:

      IEEE 802.1X Multi-Domain Authentication
      IEEE 802.1x - Auth Fail Open
      IEEE 802.1x - Auth Fail VLAN
      IEEE 802.1x - VLAN Assignment
      IEEE 802.1x - Wake on LAN Support
      IEEE 802.1x Authenticator
      IEEE 802.1x Guest VLAN
      IEEE 802.1x Local Authentication for Cisco LEAP
      IEEE 802.1x Local Authentication for EAP-FAST
      IEEE 802.1x Private Guest VLAN
      IEEE 802.1x Private VLAN Assignment
      IEEE 802.1x RADIUS Accounting
      IEEE 802.1x Radius-Supplied Session Timeout
      IEEE 802.1x Supplicant
      IEEE 802.1x with DHCP
      IEEE 802.1x with Port Security
      NAC - L2 IEEE 802.1x
      IEEE 802.1x RADIUS Accounting
    Technology - Security and VPN
    Sub Technology - Authentication Protocols
      IEEE 802.1x Supplicant
      IEEE 802.1x - VPN Access Control
    Technology - Wireless / Mobility
    Sub Technology - Wireless, LAN (WLAN)
      IEEE 802.1x Supplicant Support for Cisco LEAP
      IEEE 802.1x Supplicant Support for EAP-FAST
      IEEE 802.1x Supplicant Support for EAP-TLS

    Also i found somewere that the switch has to support something such as RADIUS tunneling attribute or something? Can't find it anymore :(

    But the reason that i ask which 802.1x components NAP require, is that i can search for some low end model, or end of life models, like a Cisco 3600 series, or 2950 series.

    Sow what 802.1x components has the switch or AP to support, in order to get NAP working?

    thanks in advance.

  • If i'm correct it should support IEEE 802.1x - VLAN Assignment for dynamic VLAN switching under NAP, but basicly the device should accept RADIUS attributes  and apply them.
    The RADIUS Attributes I used in my research are:

    64 (Tunnel Type)
    65 (Tunnel Medium Type)
    81 (Tunnel Private Group ID)

    perhaps some vendors use specific attributes for VLAN assigment, but these standard ones do the trick on my tested equipment

    In my research of NAP i found that the following cisco devices "should" support this feature, provided they have a recent IOS to support the feature:

    2940       IOS 12.1(22)EA4
    2960       IOS 12.2(25)SED
    2980       CatOS 8.4GLX
    3550       IOS 12.1(14)EA1
    3560       IOS 12.2(25)SED
    3750       IOS 12.2(25)SED
    4000*     CatOS 8.4GLX or IOS 12.1(19)EW
    4500*     CatOS 8.4GLX or IOS 12.1(19)EW
    6500       CatOS 7.2 or IOS 12.1(13)E4

    * Supervisor II+ or higher

    This list is far from complete, these are just devices that are in use in my organisation which i checked for NAP capabilities

  • Hi Muratir.

    Imho your list shows, why so many companies stuck to implement dot1x (aka 802.1x)-based solutions.

    Basically you only need the support for 802.1x-authentication using PEAP with MS-ChapV2 or certificate as EAP-Method. Then you can have an "on/off-decision" at the switchport.

    Most of the other mentioned functions in your list, which is in fact part of a featurelist for Cisco-IOS-devices, are needed because life is not fair;-)

    In a heterogeneous network-setup with multivendor-equipment as network- and systemdevice, you will need more functions, for instance for realising guest-networks fpr non-authenticated devices, additional authentication-methods like MAC-based Auth, failsafe-network-segments for a basic network-functionality in case of troubles with the dot1x-implementation, authentication-based VLAN-switching (if all your clients are able to understand a dynamic ip-address-change) etc etc.

    So at the end your total solution design defines which functions your network access devices must have to implement your special solution.

    Too complicated? Perhaps think about different enforcement methods like dhcp or inline-filtering-devices like consentry instead of using dot1x or wait for more featurecomplete versions of 802.1x in some years ;-) The last and incomplete revision of the standard is from 2004, which is far away from todays technologies.

    Best regards

  • Hi I got Radius assigned vlan(s) to work on a Cisco Aironet 1231G with firmware 12.3(8)EB. Works great! if anybody needs any help let me know.

  • Hi,

    I have got a D-Link DES-3828 which is on your list but I cannot find any option to configure dynamic vlans. The manual does not mention it at all. Do you have a configuration hint for me?

    Thanks a lot!
    28. července 2009 20:59
  • It's a year ago you asked if anyone wanted to know how you did this, I've a aironet 1100 and can't work it out. If you still have the instructions for the 1231 can you let me know how you did it please?

    ta.
    8. března 2010 14:17
  • can you post your config?

    Thanks
    12. března 2010 15:47
  • Post the config for the Radius assigned vlan(s) to work on a Cisco Aironet 1231G  is what I meant to say

    thanks

  • Does using the NAP wizard and the attributes that are referenced in there not work?

    Right click the main node of NPS
    Click the "configure NAP" link in the right hand box
    Answer the questions in the wizard.

    In general, the following attributes should work

    Tunnel PVT Group ID
    Tunnel Assignment ID
    Tunnel Medium Type
    Tunnel Type

    In my experience, Cisco devices in particular, have problems when you send the Filter-ID attribute along with any of these standard tunnel attributes, so make sure that you are not sending a combination of these, as well as the Filter ID attribute.

  • Thanks, I wasn't aware of the Filter-ID issue.

    The authorisation works fine and a NAP compliant client is accepted and placed on the correct vlan.

    My real problem was trying to get the aironet to quarantine a non compliant client when told to by the NPS server. I think it's more of a limitation of the the Aironet unfortunately.

    The aironet only seems to want to associate one vlan per SSID when I really want two.

  • Hi,

     

    I'm using nap to do authentication and vlan assignment but I have a problem.

    The authentication works but not the vlan assignement.when the radius accept the connection it sends info to the radius client:

    Tunnel-Medium-Type (65)

    Tunnel-Type (64)

    Tunnel-Private-Group(81)

    My problem is that even if the right info is sent for the attribute 81 for the to other te radius sends:

    Unknown(16777222)

    unknonw(16777229)

     

    Whereas it should send 802 and VLAN as indicated in Network Policies

     

    Please help

     

    cheers

     

    Herc.

  • grope or someone can post aironet configuration to work with radius vlans assignement (NAP my case).

    Thks.
