Cisco ISE 802.1X Client Provisioning

Hi,
I have a requirement for ISE client provisioning for both Windows and mac. I have the following setup:
1. 2 SSIDs, Guest and Employee
2. Guest is open access
3. Employee is 802.1x eap-peap (username/password)
I was wondering if client local administrator privillege is required for 802.1x provisioning for windows client? I believe it is required for MAC OS however not too sure if it may be required for Windows?
Example Employee A connect to Guest SSID and is redirect to the guest web portal. Upon login, they will be presented with the device registration portal. Upon being presented by the ISE on the supplication wizard, will they be requested for local administrator/domain admin privillege to install the supplicant wizard package/provisioning agent successfully?
Any suggestion is appreciated.
Thanks.

Hi,
Appreciate for the feedback.
Thanks

ISE 1.2 Client Provisioning Page Customization

Hi All,
Is it possible to customize Client Provisioning Page. We are using ISE version1.2
I could see from switch port authentication sesssion that it is being redirected to guest portal with session ID.
however on the host machine itself it gets redirected to a different URL.
Regards
Sameer

please have a look on Configuring Client Provisioning guide:

Cisco ISE - Reauthentication of client if server becomes alive again

Dears,
I have this case where Cisco ISE server is used to authenticate & authorize clients on the network.
I configured the switch port to authorize the client in case the ISE server is dead (or not reachable).
The thing is that I want to reauthenticate the client once the ISE server becomes alive again but I am not able to.. ("Additional Information is needed to connect to this network" bullet is not appearing and the client PC remains authenticated and assigned to the VLAN.
Below is the switch port configuration:
interface FastEthernet0/5
switchport access vlan 240
switchport mode access
switchport voice vlan 156
authentication event server dead action authorize vlan 240
authentication event server alive action reinitialize
authentication host-mode multi-domain
authentication order dot1x mab
authentication priority mab
authentication port-control auto
mab
dot1x pae authenticator
spanning-tree portfast
Anyone can help?
Regards,

Please check whether the switch is dropping the connection or the server.
Symptoms or Issue
802.1X and MAB authentication and authorization are successful, but the switch is dropping active sessions and the epm session summary command does not display any active sessions.
Conditions
This applies to user sessions that have logged in successfully and are then being terminated by the switch.
Possible Causes
•The preauthentication ACL (and the subsequent DACL enforcement from Cisco ISE) on the NAD may not be configured correctly for that session.
•The preauthentication ACL is configured and the DACL is downloaded from Cisco ISE, but the switch brings the session down.
•Cisco ISE may be enforcing a preposture VLAN assignment rather than the (correct) postposture VLAN, which can also bring down the session.
Resolution
•Ensure the Cisco IOS release on the switch is equal to or more recent than Cisco IOS Release 12.2.(53)SE.
•Check to see whether or not the DACL name in Cisco ISE contains a blank space (possibly around or near a hyphen "-"). There should be no space in the DACL name. Then ensure that the DACL syntax is correct and that it contains no extra spaces.
•Ensure that the following configuration exists on the switch to interpret the DACL properly (if not enabled, the switch may terminate the session):
radius-server attribute 6 on-for-login-auth
radius-server attribute 8 include-in-access-req
radius-server attribute 25 access-request include
radius-server vsa send accounting
radius-server vsa send authentication

Cisco ISE: 802.1x [EAP-TLS] + List of Applicable Hot-Fixes

Dear Folks,
Kindly suggest the list of all possible Hot-Fixes required for the Cisco ISE EAP-TLS solution... We have applied 9 HotFixes so far. But, still the connectivity is intermittent. Is there any list for all applicable Hot-Fixes?
OS = Win 7 SP1 (32/64 Bit) and Win 8

Hi Mubasher
KB2481614:      If you’re configuring your 802.1x settings via Group Policy you’ll see      sometimes EAP-PEAP request from clients in your radius server log during      booting even if you’ll set EAP-TLS. This error happened in our case with      1/3 of the boots with some models. The error is caused by a timing problem      during startup. Sometimes the 802.1x is faster and sometimes the Group      Policy is, and if the 802.1x is faster than the default configuration is      taken, which is PEAP. Which lead to a EAP-NAK by the radius server.
KB980295:      If an initial 802.1x authentication is passed, but a re-authentication      fails, Windows 7 will ignore all later 802.1x requests. This hotfix should      also fix a problem with computers waking up from sleep or hibernation –      but we’ve disabled these features so I can’t comment on them.
KB976373:      This hotfix is called “A computer that is connected to an IEEE      802.1x-authenticated network via another 802.1x enabled device does not      connect to the correct network”. I can’t comment on this, as we’ve not      deployed 802.1x for our VoIP phones at this point.I would guess it is the      same for Windows 7 too. The linked article tells you to install the patch      and set some registry key to lower the value.
KB2769121:      A short time ago I found this one: “802.1X authentication fails on a      Windows 7-based or Windows 2008 R2-based computer that has multiple      certificates”. At time of writing I’m not sure if it helps for something      in my setup. According to the symptoms list of the hotfix, it does not,      but maybe it helps for something else, as the one before does.
KB2736878:      An other error during booting – this time it happens if the read process      starts before the network adapter is initialized. Really seems that they      wanted to get faster boot times, no matter the costs.
KB2494172:      This hotfix fixes a problem if you’ve installed a valid and invalid      certificate for 802.1x authentication. The workaround is just deleting the      invalid certificate. I’m not sure at this point if it affects also wired      authentication.
KB976210:This      problem occurs only during automated build processes and if you use an EAP      method which needs user interaction – as I don’t do that I can’t comment      on this hotfix.

Cisco ISE Guest Login without provisioning

Hi,
I have setup the ise based on https://supportforums.cisco.com/docs/DOC-26442 whereby I have an authorization rule for CWA and an authorization rule for guestflow with provisioning. All is working great, however I was wondering if it may be possible to setup the ise with the following scenarios with dual ssid:
1. user login to guest ssid and redirects to guest web portal and input guest credential created by sponsor (this is working well)
2. user login to guest ssid and redirects to guest web portal and input credential from AD goes to provisioning (this is working well)
3. user login to guest ssid and redirects to guest web portal and input credential from specified AD group and get internet/network access without provisioning.
For point 3, I was wondering if it may be possible and if so on how it may be accomplished? I have attached the present Authz rule for reference as well as the rule I have tried which does not seems to be working.
Any help is appreciated!
Thanks.

No it doesn't, you can test the same , while editing the wireless SSID profile, opting authentication method as smart card other than PEAP/EAP.

ISE, BYOD: guest clients provisioning

Hello!
The question is about provisioning different types of wifi clients through the ISE Guest portal.
ISE 1.1.4, WLC 7.4.100 (Guest WLAN uses MAB)
Suppose, there are two groups of wireless clients:
1) guest user, which credentials are created through the ISE Sponsor Portal
2) domain user, who has credentials in ActiveDirectory
The aim is to provision domain user, and not provision guest user.
When client connects to Guest SSID and opens the browser, he is redirected to ISE Guest portal.
When client uses domain user, he is provisioned, and when uses guest credentials he is not provisioned
How ISE understands, that domain user must be provisioned and guest user must not be provisioned if Web portal is configured to provision everyone?
(Web Portal -> Settings -> Enable Self-Provisioning flow)

The answer is that typically you either know that MAC address or you have someting installed (NAC agent?) and fulfill some requirements.
Alternative, you can perform CWA first (and...)
Then if user is part of guest users -> allow internet only access
If user is part of AD -> send him to do registration.
Authorization policy allows you to use "identity group" as part of condition.
If device registered -> allow full access. (just an idea).

Cisco ISE 1.2, Clients not getting IP address in closed mode

Hello, I am running closed mode on my switchports. I have an issue where some clients come in in the morning, try to login, and will not get network access. I see that this is because they do not get an IP address. I am using MAB for authentication currently. They appear to MAB correctly and get Authorized in ISE, but they do not get an IP. Therefore, they also do not get the DACL of permit ANY. It's like the port gets de-authenticated during the night. Usually when the machine is rebooted it will come up with an IP address. Here is my switchport config...

switchport mode access
switchport voice vlan 64

Cisco ISE: 802.1x Timers Best Practices / Re-authentication Timers [EAP-TLS]

Dear Folks,
Kindly, suggest the best recommended values for the timers in 802.1x (EAP-TLS)... Should i keep default all or change or some of them?
Also, what do we need reauthentication timers? Any benefit to use it? Does it prompt to users or became invisible? and What are the best values, in case if we need to use it?
Thanks,
Regards,
Mubasher
My Interface Configuration is as below;
interface GigabitEthernet1/34
switchport access vlan 131
switchport mode access
switchport voice vlan 195
ip access-group ACL-DEFAULT in
authentication event fail action authorize vlan 131
authentication event server dead action authorize vlan 131
authentication event server alive action reinitialize
authentication open
authentication order dot1x mab
authentication priority dot1x mab

Hello Mubashir,
Many timers can be modified as needed in a deployment. Unless you are experiencing a specific problem where adjusting the timer may correct unwanted behavior, it is recommended to leave all timers at their default values except for the 802.1X transmit timer (tx-period).
The tx-period timer defaults to a value of 30 seconds. Leaving this value at 30 seconds provides a default wait of 90 seconds (3 x tx-period) before a switchport will begin the next method of authentication, and begin the MAB process for non-authenticating devices.
Based on numerous deployments, the best-practice recommendation is to set the tx-period value to 10 seconds to provide the optimal time for MAB devices. Setting the value below 10 seconds may result in the port moving to MAC authentication bypass too quickly.
Configure the tx-period timer.

ISE 1.0 Posture and Client provisioning

I've configured 802.1x with dynamic VLAN for users and MAB for phones - it works fine. Now I wanna to implement client provisioning and posture validation for users. After reading ISE user guide there are still several big questions:
1. Is it possible to combine 802.1x and posture? (it was not recommended with NAC)
2. How can I bind existing 802.1x authorization profile and posture policy?
3. What is a switch configuration for client provisioning to work(redirect, quarantine zone, download NAC agent)?
4. Do ISE posture and client provisioning have L2 virtual gateway, trusted and untrusted ports, as in NAC?

With ISE you can perform 802.1x first and after that optionally you can perform posture. This is done with Radius, that's why it's really and completely out of band, and there's no such concept of trusted or untrusted port because the traffic is never inline.
Still, with ISE you have another option of "inline Posture", in which there's trusted and untrusted ports. I guess that's for some specific cases in which you can't go out-of-band.
On the other hand, so called "out-of-band" NAC was really always an inline solution, only after the user has authenticated and security policies have been verified then the user goes "out-of-band".

Cisco ISE authentication failed because client reject certificate

Hi Experts,
I am a newbie in ISE and having problem in my first step in authentication. Please help.
I am trying to deploy a standalone Cisco ISE 1.1.2 with WLC using 802.1x authentication. The user authentication configured to be checked to ISE's internal user database for early deployment. But when the user try to authenticate, they failed with error message in ISE :
Authentication failed : 12321 PEAP failed SSL/TLS handshake because the client rejected the ISE local-certificate
I've generate a certificate for ISE using Windows Server CA and replace ISE's self-signed certificate with the new certificate but authentication still failed with the same error message. Must I generate a certificate for WLC also? Please help me in solving this problem.

Ratna

Certificate-Based User Authentication via Supplicant Failing
Symptoms or

IOS 8.x Apple users and CISCO ISE native supplicant provisioning not working

Hi there guys ,
I was wondering if anybody else have the following problem:
Apple iOS 8.x users are not able to register their devices on the ISE portal (native supplicant provisioning).
After they receive the redirection from the WLC, they freeze. Apple 7.x users have no problem.
ISE is version 1.2.1.198 patch 2. WLC is running 8.0.102.14.
Anybody experienced the same?
MB

I am also running ISE 1.2.1.198 patch 2 with 8.0.100. I am testing with an iPad running IOS 8.1. The device will register in the registration portal, but is not being classified as an IOS device within client provisioning, I believe. It is getting profiled as a workstation even though all apple device profiles are enabled. I have an authorization policy for registered devices, and ipad, iphone, ios devices to gain access to the network without going through posture assessment. I then have my posture assessment authorization rules with apple IOS devices set for a ssid native supplicant profile. I keep getting an error page on the iPad when connecting to the ISE SSID saying "Client Provisioning Portal ISE is not able to apply an access policy to your log-in session at this time. Please close this browser, wait approximately one minute, and try to connect again". It gives this message over and over. If I turn off the posture checking authorization profiles, the IOS device is selected as a rule further down which tells me that ISE does not recognize it as an IOS device in the profiling or client provisioning.

Cisco ISE Deployment suggestion required

Require Assistance on Cisco ISE Deployment for below scenario
-- We have Three Cisco ISE Appliances and Client has taken Advance Subscription License for 500 users
-- Client has DC & DR and needs to deploy the Cisco ISE in one Main Office which connects to DC & DR on MPLS Links
-- Client suggestion was to deploy one ISE node ( Admin + M&T + Policy Server ) in DC and its Standby Secondary in DR
     and only deploy Policy Server in Main Office.
     Idea behind the design is that ,
     1) If DC fails , Cisco ISE related logs will get generated on DR and any Cisco ISE related request will be taken care by Local Policy Server in Main Office .
      2) If Local Policy Server Fails , then ISE node in DC will act as Secondary backup and DR will act Teritary Backup
      below is view

Cisco ISE (1.3) Posture without Client Provisioning

Hello readers,
Is it possible to set up Cisco ISE with posture without Client Provisioning?
My customer deploys the NAC Agent via MS SCCM. We prefer a access accept + DACL during the pending state instead of redirecting to client provisioning. But the NAC Agent will only communicate when we redirect to client provisioning.

ISE 1.2 device registration with MAB only, no client provisioning

Hello,
Is it possible for AD users (no guest users) to walk through the Device Registration Self Registration without Client Provisioning ?
I do not want to push certificates or native supplicant profiles to client devices.
I would just want AD users to register their MAC address, if MAC is not known. Add the MAC to some sort of group.
Then if MAC is known (in this group), skip registration and allow full access to the VLAN.
Right now, i am stuck on the registration portal that says "The system adminstrator has either nog configured or enabled a policy for your device". ?? It is true that my Client Provisioning screen is empty.
Am i really obliged to use native supplicant provisioning to register my device ?
GN

Hi
Device Registration web auth is a process where you can configure user without client provisioning.
In this scenario, the guest user connects to the network with a wireless connection that sends an initial MAB request to the Cisco ISE node. If the user’s MAC address is not in the endpoint identity store or is not marked with an AUP accepted attribute set to true, ISE responds with a URL redirection authorization profile. The URL redirection presents the user with an AUP acceptance page when the user attempts to go to any URL.
1. A guest user connects to the network using a wireless connection and has a MAC address that is not in the endpoint identity store or is not marked with an AUP accepted attribute set to true, and receives a URL redirection authorization profile. The URL redirection presents the user with a AUP acceptance page when the guest user attempts to go to any URL.
2. If the guest user accepts the AUP, their MAC address is registered as a new endpoint in the endpoint identity store (assuming the endpoint does not already exist). The new endpoint is marked with an AUP accepted attribute set to true, to track the user’s acceptance of the AUP. An administrator can then assign an endpoint identity group to the endpoint, making a selection from the Guest Management Multi-Portal Configurations page.
3. If the guest’s endpoint already exists in the endpoint identity store, the AUP accepted attribute is set to true on the existing endpoint. The endpoint’s identity group is then automatically changed to the value selected in the Guest Management Multi-Portal Configurations page.
4. If the user does not accept the AUP or an error occurs in the creation of the endpoint, an error page appears.
5. After the endpoint is created or updated, a success page appears, followed by a CoA termination being sent to the NAD/WLC.
6. After the CoA, the NAD/WLC reauthenticates the user’s connection with a new MAB request. The new authentication finds the endpoint with its associated endpoint identity group, and returns the configured access to the NAD/WLC.
