• EAP - TLS uses WEP?

  Why do you need to configure WEP as a data encryption when you use EAP - TLS?

  'Ensure that the data encryption is set to WEP.

  You cannot use WPA2?

  Remco,

  1. what should I do to configure EAP - TLS?

  In order to configure EAP - TLS, the only configuration on the WLC is selection of 802. 1 x 2 layer security screen.

  2. users must have a certificate of the user and computers need a computer certificate. IAS server needs a server certificate.

  You RADIUS server must have a certificate and this must be added to the list of trusted certificates on each client. There is no configuration required on the side of the controller for this.

  3. I want to use WPA/PWA2 enterprise with AES encryption. In all the documents, you can see that the client is configured with WEP.

  By default, if you choose 801.x on layer 2 security, WEp is used as the encryption. You must understand that these are two different things. One is the encryption (TKIP/AES and the other is the 801.x authentication). So if you want to use WPA2 with EAP - TLS, you must select WPA1 + WPA2 as layer 2 security, then 802. 1 x on the same screen in "Auth key Mgmt" select 802. 1 x

  Let me know if that answers your question.

• LEAP EAP - TLS on WLC

  Hello

  I need to deploy authentication of certificate based for some devices of client for Intermec for a customer. I intend to use a separate SSID for this. There are other existing SSID who based radius authentication.

  question: if I don't select any server radius for this eap tls ssid and select only "BOND", going to work? Or will the WLC always find already defined radius servers and authentication failure?

  Question2: If above is not possible, I have to go for eap tls with ACS. someone had some easy steps to get eap tls operational? (1252, wlc 4400, acs 4.1 windows CA LAP)

  concerning

  Joe

  You will be able to use local for jump car as long as you do not specify a server radius on this ssid. Then you can have a different ssid to break the eap - tls pointing to a RADIUS.

• Machine based authentication using EAP - TLS, MS CA and 5.2 of the ACS

  I use ACS 4.2 for Windows for a couple of years now and I'm pretty comfortable with it.  5.2 model is much more different than what I expected.  We downloaded the trial in our laboratory for 90 days, and I try to get 802. 1 x wired works so we can be sure that we want to buy it.  I've looked everywhere and I have been unable to find some basic instructions on how to configure the following in a step by step process scenario:

  1. integrated AD

  2 EAP - TLS

  3 certificates

  4 Microsoft CA

  5. the applicant is XP SP 3

  6 non-Cisco 802.1 x compatible switches (switches are not the question)

  I got GANYMEDE to work fairly easily, but I am confident the issues I have are user based :).  Does anyone know of a doc somewhere that goes on a scenario like this (in addition to the user manual and docs of migration ISBN)?  Also, we have the assurance of software on our box 4.2 - TAC support questions we have on the 5.2 box while we are it do demonstrations?

  Thanks in advance.

  Hello, Christopher.

  I'll try to give you some tips to achieve what you want.

  Additional info can be found in the user guide:

  http://www.Cisco.com/en/us/docs/net_mgmt/cisco_secure_access_control_system/5.2/user/guide/acsuserguide.html

  1. in the identity store / Active directory, check "enable machine authentication.

  2 import a certificate for ACS

  Go to System Administration > Configuration > Local Server Certificates > Local certificates and click the Add button.

  Select how you want to import the certificate, and then verify the Protocol EAP

  3. Add your switches as aaa clients

  Access network resources > network hardware and the AAA Clients, click on create and add configure address IP + shared secret for the RADIUS.

  4-go to access policies > Access Services and click on create a new access service.

  Select the selected Type of Service and network access in the list.

  Verify the identity, group mapping and authorization

  5 - go to the access policies > rules of selection and select "Rule based selection result" if not already done, then click Customize at the bottom right of the screen, and then add the properties that allows you to match your device with which you want to do TLS.

  You can use the IP address of devices, or you can create a NDG (in network resources), assign devices to the NDG and match this NDG in your rule.

  If all your switches RADIUS will make eap - tls, you can change the rule

  Rule-1

  Ray game

  Default network access

  While in the result, you choose your service of access created in step 3.

  6 - go to the access policies and click on the access service that you created in step 3. In the allowed Protocols tab, see EAP - TLS

  7. unfold your access service menu, and then click identity. Select your ad as being the source of the identity

  8. check that the 'Allowed access' rule is selected in the authorization to access your service

  These measures define your devices, and then create a rule to say that ACS must use an individual service for this access devices and set this access service to use AD as authentication.

  Again, what are the basic steps, he may miss some things to do depending on your configuration, but I hope this will help you.

  ACS 5 may be difficult at first, but once you get your hands on it, you will see that it is powerful.

• Wrong with EAP - TLS with Wireless before Windows logon

  Evil begins with a list of equipment;

  5508 WLC

  3502i AP

  Cisco ACS 5.3

  Clients Windows 7

  WLAN is set up with WPA2 AES with 802. 1 x for key management.

  Customer is set up with WPA2/AES, authentication method is Microsoft: card chip or other certificate on the computer. Authentication mode authentication is the user or computer.  The client is configured to use a certificate on the computer.  "It only works if the authenticating user or computer is seected."  If I use computer authenticate option... it says that it cannot find a certificate to use for the EAP.

  ACS is configured to allow only for the EAP - TLS protocol.

  We have created a stand-alone CA server and distributed CA certificates root and client authentication for all test systems.

  This whole process with EAP - TLS works very well if you are already connected to the machine, with the credentials of the cache.  Once I disconnect the Windows 7 client, I lose the connection to the WLAN.  We want to stay connected to the WIFI network.  W PEAP / MSCHAPV2 works very well with stay connected to the WLAN, but we want to use EAP - TLS.

  Any ideas?

  Thanks in advance,

  Ryan

  Hi Ryan,

  You actually answer your own question :) The reason for the fault is because the computer account doesn't have a certificate, so when your computer account user cannot connect to maintain the session going, and so you are disconnected. Provide the computer with a certificate account and your problem will be solved.

• ACS 5.4 EAP - TLS: the system of null or invalid message met CSCOacs_Internal_Operations_Diagnostics 31201

  Hi all

  I am trying to configure wireless with 802.1 x, authetication in the EAP - TLS computer with digital certificates, but it does not work.

  It runs on ACS 4.2.

  The message is ACS CA is not known, but it is configured correctlry.

  I have a "Wireless" accesses with identity store AD1 policy. I also tried to set up CN, SAN and a lot of identity store sequences, same results.

  At the time of authentication, I also see this log message:

  System encountered null or invalid message

  CSCOacs_Internal_Operations_Diagnostics

  31201

  I could be associated to?

  Can someone help me?

  THX,

  Andrea

  I see the certificates installed have been already expired.

  Regarding your second question, where do you see a mistake. I suspect a defect.

  CSCtw48906    Error due to an empty message (vector buffer), sent to the enforcement process

  Symptom: An Error Message is seen inlogs: message of the ERROR encountered CSCOacs_Internal_Operations_Diagnostics 31201 null or invalid system

  Conditions: ACS 5.2

  Solution: The issue is cosmetic. This message can be ignored.

  Under the guidance of the Director, this occors error when a message empty (vector buffer) that was sent to the runtime on the message Bus and it seems to be "cosmetic" question

  In default, debugging is attached. If you wish, you can activate the debbuging level performance logs and match symptoms.

  Here are the steps to generate support bundle.

• Authentication EAP - TLS with ACS 5.2

  Hi all

  I have question on EAP - TLS with ACS 5.2.

  If I want to implement the EAP - TLS with Microsoft CA, how authentication computer and user will be held?

  Understand that the cert is required on the client and the server end, but is this certificate to the computer links or links to individual users?

  If the links to the user, and I have a shared PC connection by few users, is that each user account will have their own certificates?

  And each individual user will have to manually get the CA cert? is there another method that my environment has more than 3000 PCs.

  And also if it binds to the user, any user can get their CA cert with their AD username and password, if they bring in their own device and try to get the CA certificate, they will be able to properly install the cert in their device on the right?

  I hope you guys can help with that. Thank you.

  Hope this will answer most of your questions:

  Client certificate or user

  http://www.Cisco.com/en/us/Partner/Tech/tk59/technologies_tech_note09186a00804b976b.shtml#T10

  Computer certificate

  http://www.Cisco.com/en/us/Partner/Tech/tk59/technologies_tech_note09186a00804b976b.shtml#T15

  In the case of EAP - TLS we have the certificate of computer and user installed on the machines.

• ACS supports several Active Directory domains to 802. 1 x EAP - TLS?

  Hello

  I'm looking to implement 5.2 ACS using 802. 1 X, we have two distinct areas of AD.

  Now... That's the tricky part...

  One switch must support two ads, if an AD1 computer, it will be authenticated to the ACS using AD1 and applied to the VLAN1, whereas a machine located in AD2 is authenticated to AD2 and applied to VLAN 2.

  I'm looking for machine authentication, user authentication, so I guess I'll need two certificates of import of each ad.

  Can any expert please let me know if they think that this will be possible please?

  Thank you very much

  Yes ACS can support several areas of the AD, but you need to configure one of your AD domain name and the other as a LDAP database and it will not work because you plan to use eap - tls.

  The question I have is how ACS version do you use? If you use ACS 5.x, you can set up and storage of identity of sequence, so if the user is not you can move to the next store and this will prevent you from installing two certificates on each machine.

  You can then configure an allow rule for separate containers on which there are workstations (that's assuming that the machine authentication is used) for the AD database or the Protocol LDAP database, and then assign the vlan based on that.

  Thank you and I hope this helps!

• Expired password AD with EAP - TLS

  Hello

  It's probably a stupid question but this is. I have LWAPPs a WLC with ACS using EAP - TLS with a backend ActiveDirectory. I connect a laptop to the network with a wired connection and the connection to the domain. The cert of the user is then pushed to the laptop by group plicies or something else.

  Now, I can disconnect from the cable network and reboot the laptop. Connection to the laptop is via the credentials cached and it authenticates on the wireless network using EAP - TLS, well.

  The quiestion is is it a mechanism in this configuration for againg password the passowrd AD user that is used to connect to the Windows profile in the first place. It is necessary to reconnect to the network wired to do this or allow a change passowrd more once that the password years wireless?

  Thank you

  Pat

  With eap - tls, your wireless connection is insensitive to the user password. If the user will be able to change his windows password without having no problem with the wireless I know

• PEAP EAP/TLS, PORTEGE with WinXP sp2 Tablet Edition problem

  We have: Rev AiroNet350 Cisco with WPA - EAP: Freeradius with EAP/TLS and PEAP, tablet PC PORTEGE with WinXP sp2 configuration.

  This problem discribed in http://wiki.freeradius.org/index.php/FAQ#PEAP_Doesn.27t_Work
  Perhaps to solve this problem we need a fix (http://support.microsoft.com/kb/885453/en-us), but microsoft support said to contact the laptop manufacturer.
  Can someone help me with this problem?

  Hmmm I m not an expert in this area, but it seems that the MS OS update is necessary. (I hope)
  The preinstalled Windows operating system is a simple OEM version and generally all updates should be possible. However, if MS guys told you to communicate with the manufacture of the laptop, you can contact the maintainer authorized Toshiba in your country for details.

  But I studied a bit on the net and found this site useful:

  1. 802. 1 X is based on communication between your router and a RADIUS authentication server. If you use WEP, WPA or WPA2 with dynamic keys, 802. 1 X debugging following tips may be useful:
  a. reintroduce the same RADIUS secret in your wireless router and the RADIUS server.
  b. configure your RADIUS server to accept the request of the RADIUS of the IP address of your router.
  c. use ping to check the accessibility of router-server.
  d. package watch LAN account to verify that RADIUS and answers queries are fluid.
  e. use an Analyzer like Ethereal Ethernet to watch RADIUS success/failure messages.
  f. for XP SP2, turn on Wzctrace.log by typing "command netsh ras set followed * activated.

  2 if RADIUS is flowing but are rejected requests for access, you may have a problem of incompatibility or credential X Extensible Authentication Protocol (EAP) 802.1. This setting depends on Type EAP. For example, if your RADIUS server requires EAP - TLS, then select 'Card chip or other certificate' of your adapter wireless network properties / authentication Panel. If your RADIUS server requires PEAP, then select "Protected EAP" of the adapter. If your RADIUS server requires EAP-TTLS, then you will need a third-party wireless like AEGIS or in Odyssey client.
  Make sure that this specific EAP properties match for your adapter and the server, including the server CA certificate root trust Server domain name (optional but must match when it is specified) and the customer (EAP-MSCHAPv2, EAP - GTC) authentication method. When you use PEAP, use the control panel to 'Configure' CHAP to prevent Windows from automatically re-use of your connection.

• ISE and EAP - TLS

  Hello

  We plan on implementing eap - tls for our iPads company and in the past, I've successfully tested it authentication with the ACS5.3, but now that we moved to ISE (1.1.1.24) I get an error.

  Result of the strategy of the 22045 identity is configured for password based authentication methods but received certificate authentication request

  I tried two different profiles, one with a certificates and credentials of the AD and the other with just the certificates but the error message are the same for both.

  EAP - TLS is enabled in the result of the 'Access to the network by default' authentication.

  Anyone can shed some light on where I'm wrong?

  Thank you

  Martin

  Yes that's right, the certificate that is presented to the ISE does not include the identity of the client, this is the reason why the attempt fails.

  Thank you

• EAP - TLS with WLC 4404 (choose which layer option 2)

  Hi all

  I want to install a WLAN that uses EAP - TLS.

  WiFi PC <----->LWAP <------>WLC <---->Radius Server

  Should the layer tab 2 for security on the WLC which option I use for the following: -.

  Security Layer 2 (I'm assuming that WPA + WPA2 than what laptops will use)

  Key auth Mgmt?

  I'm a little confused by the 802. 1 x in two of these fields, a security layer two and one for Auth key Mgmt?

  Thx a lot indeed guys,.

  Ken

  You would choose layer 2 security: WPA + WPA2

  Then in the settings WPA + WPA2 choose political WPA2 with WPA2 encryption. Under authentication key Mgmt select 802.1 x.

  Now if you need the use of WPA policy, then also choose TKIP for this.

  Choose your radius servers so for your AAA server tab.

  That's all.
