NAC Agent Customization Distribution

Looks like the NAC agent customizations can be done only when the client PC pulls
the install from the CAM. Our PCs do not have admin rights and the software will be pushed through a software
distribution tool. Is there any way to distribute the software with the customization file , just like there is an option
to install with the agent configuration file?
Thanks
Shaffeel

Hi Shaffel,
You cannot include the branding files on the MSI installation package of the Agent.
I have not much experience with the centralized client management tools, but you could try a workaround by pushing those files to the client at the appropriate location and then restart the Agent.
The files to be pushed are the ones you prepared on the branding file to be uploaded to the CAM.
The location of the files is documented at this page:
http://www.cisco.com/en/US/docs/security/nac/appliance/configuration_guide/48/cam/m_agntd.html#wp1606140
Specifically:
In a system that has NAC Agent installed, you can find the "nac_login.xml" file in the "C:\Program Files\Cisco\Cisco NAC Agent\UI\nac_divs\login" directory.
The "nacStrings_xx.xml" file is available in the supported location. The "xx" indicates the locale. In the system that has NAC Agent installed, you can find a complete list of the files in the "C:\Program Files\Cisco\Cisco NAC Agent\UI\cues_utility" directory.
The files are available in the directories mentioned above when the Agent is installed at the default location. If the Agent is installed at a different location, then the files would be available at "\Cisco\Cisco NAC Agent\UI\nac_divs\login" and "\Cisco\Cisco NAC Agent\cues_utility".
I hope this helps.

Federico

ISE 1.1.2 - Agent Customization Package

Hi there
I have created a NAC Agent Customization Package and sucsesfully uploaded the 'custom.zip' file to - Policy>Policy Elements>Results>ClientProvisioning>Resources.
However, when I try to edit my Client Provisioning Policy and select AgentCustomizationPackage, my custom package dosn't appear on the drop down list, so i'm unable to select it!
Anyone any ideas?
Cheers
Tim

Hi Tim,
It is possible to us Agent Customization Packages using temporary "Update Feed URL" in "Administration" --> "System" --> "Settings" --> "Client Provisioning". If you use attached file as example the "Update Feed URL" will look like http(s)://fqdn/provisioning-update.xml
You may use attached files as example, this one includes the Cisco logo.

NAC Agent Distribution on Endusers w/o Administrative priviliges

Im looking for options for distributing NAC agent. I would like as many options as possible to see if it fits any of my scenarios.
Any ideas or current use cases anyone has done?
Thanks in advance

David,
Currently not possible. NAC agent runs as a program and has to run under user credentials for it to be able to identify the user correctly that is being NAC'd. In later versions there's a service component of the agent, but the SSO functionality still relies on the Agent being loaded correctly. Your option is to run a delay script (detailed here: http://tinyurl.com/25d2aua ) and once that passes, then call your other scripts which do the mapping.
Also if you're having such inordinate delays in the initial SSO process, ensure you have all the ports open that need to be open, including the IP FRAGMENTS and ICMP to all your DCs in the Unauthenticated Role.

NAC Agent Distribution

Hello,
I have updated NAC from 4.7 to 4.8, I wanna distribute Nac agent throughtout the campus on 1000 PC,how can i do it,i have downloaded a nac agent from cisco site nacagentsetup-win-4.8.0.32 Is it right agent patch that i have to distribute ????????????????????
I can distribute through BigFix or Microsoft System Management Server (SMS), DO anybody have a step by step procedure to do that.
Thanks

Hi,
Because it is initial deployment, there is another reason to use the automatic method to install the Agent on each PC directly from the CAM.
For it to happen, you only need to configure the CAM login page to "Require use of Agent":
So, then every client that doesn't have the Agent, just needs to open a web browser, it gets redirected to the NAC login page (assuming everything is working fine), and after login, the agent is offered to download and install.

NAC AGENT - DISCOVERY HOST IP ADDRESS with AD

Hi,
We have deployed a Cisco NAC Agent in our network with GPO update... The deployment model is L3 OOB / Real IP Gateway.
The issue is that, we need to put the IP address in each host manually to start communicating with Cisco NAC Manager.
Is there any way to make it automatic?
Regards,
Mubasher

Hi Mubashir,
I faced the same problem with cisco ISE and Tiago's response actually helped see below.
" You can also distribute the NACAgentCFG.xml file with that value set.
Please find here detailed info regarding this file:
http://www.cisco.com/en/US/docs/security/nac/appliance/configuration_guide/48/cam/m_agntd.html#wp1348376. "
In that link, read the section: Agent Customization Settings
From a NAC agent that has successfully been deployed with the IP configured , go to the NAC agent installation folder
C:\Program Files (x86)\Cisco\Cisco NAC Agent , and copy the NACAgentCFG.xml , open with wordpad and edit the line
IP of PDP node or ISE standalone server
Then place the edited NACAgent.xml file in the same folder as the one where your GPO will pick the agent from. When the Agent is installed , it automatically picks the configs from the .xml file.

Henry

NAC Agent Login Dialog Not Appearing - ISE 1.1.1 issue ?

Agent Fails to Initiate Posture Assessment
The NAC agent is properly installed on a Windoes 7 , IE 9 machine, the certificates from ISE ADM PRI are installed in trustable certificate store in the client machine but is a selfsigned ISE certificate.
The reports / USER / Profiling report says the Provisioning Agent has completed the assessment ok.
The redirected URL is working fine (SEE Evidence)
We are always prompted to install the NAC agent again or looking at the additional prompted information wait for the NAC agent to load and complete.
The operations status remains with postering status pending forever and nothing else happens.
Symptoms or Issue
The agent login dialog box does not appear to the user following client provisioning.
Conditions Cisco Says this issue can generally take place during the posture assessment phase of any user
authentication session.
Cisco Advises as Possible Causes There are multiple possible causes for this type of issue. See the following
Resolution descriptions for details of what was already tested by us and please see the atached files for your switch configuration and evidences. .
CISCO SUGGESTED POSSIBLE CAUSES AND RESOLUTIONS
Resolution • Ensure that the agent is running on the client machine. ALL TESTED OK
• Ensure that the Cisco IOS release on the switch is equal to or more recent than
Cisco IOS Release 12.2.(53)SE. - OK
• Ensure that the discovery host address on the Cisco NAC agent or Mac OS X
agent is pointing to the Cisco ISE FQDN. (Right-click on the NAC agent icon,
choose Properties, and check the discovery host.) - OK (See evidence)
• Ensure that the access switch allows Swiss communication between Cisco ISE
and the end client machine. Limited access ACL applied for the session should
allow Swiss ports: ALL CONFIGURED as CISCO GUIDELINES OK (SEE EVIDENCE)
• If the agent login dialog still does not appear, it could be a certificate issue.
Ensure that the certificate that is used for Swiss communication on the end client
is in the Cisco ISE certificate trusted list. (ALL CHECKED OK SEE EVIDENCE)
• Ensure that the default gateway is reachable from the client machine. (TESTED OK)

Hi.
Can you paste all the ACLs on your switch especially the webauth redirect ACL which should deny traffic towards the PSN.

Is it possible to run Posture using ISE 1.2 without NAC Agent provisioning?

Is it possible to run Posture using ISE 1.2 without NAC Agent provisioning?
-My customer does not want to push NAC Agent installation on BYOD type of computers (non-managed by the company computers).
-The requirement is to check for posture only company owned wired, wireless, and VPN connected Windows computers. The rest of the endpoints should be considered as posture incompliant, and limited access to the network should be allowed.
-No certificates are used.
-I’ve configured the required posture check, and it all works fine if a PC has NAC Agent manually installed (without ISE Client Provisioning). However, when I use a PC without NAC Agent, it is redirected to Client Provisioning Portal and is stuck there as Client Provisioning is deliberately not configured in ISE.
-If I remove Posture Remediation Authorization Profile that does URL redirect, the posture does not work.
-For now I'm testing it on wired endpoints.
Is there a way to configure ISE to fulfill the listed above requirements?
Any ideas would be appreciated.
Thanks,
Val Rodionov

Everyone who finds reads this article,
I'm answering my own quesiton "Is it possible to run Posture using ISE 1.2 without NAC Agent provisioning?"
The answer is Yes.
After doing research and configuration testing I came up with a solution, and it works fine for wired and VPN connections. I expect it to work on wireless endpoints as well.
ISE configuration:
Posture General Settings - Default Posture Status = NonCompliant
Client Provisioning Policy - no rules defined
Posture Policy - configured per requirements
Client Provisioning (under Administration > Settings) - Enable Provisioning = Enable (it was disabled in my first test)
Authorization Policies configured as regular posture policies
The result:
After successful dot1x authentication posture redirect happens. If the PC does not have NAC Agent preinstalled, the browser is redirected to Client Provisioning Portal and a default ISE message is displayed (ISE is not able to apply and access policy... wait one minute and try to connect again...). At the same time, the endpoint is assigned NonCompliant posture status and proper authorization policy is applied. This is what I wanted to achieve.
If NAC Agent was preinstalled on the PC, after successful dot1x authentication the NAC Agent pops up and performs posture check. If posture is successful, posture compliant authorization policy is applied. If posture check fails, NonCompliant posture status is assigned and posture non-compliant authorization policy is applied. Which is the expected and needed result.
The only part that is not perfect it the message displayed to the end-user when posture is about to fail. I did not find a place to change the text of that message. I might need to open TAC case, so this file can be manually found and edited from CLI (root access).
Best,
Val Rodionov

Cisco NAC Agent 4.9.1.682 Problems with Mac Os X 10.7.4

Hi
My Cisco NAC Agent (version 4.9.1.682) doesn't work since I upgraded my Mac OS X 4 months ago, This happens every time with CISCO and MAC when there is a new update and it always seems to take forever to fix.
The NAC agent just keeps asking for my login in details even though there are correct (I can log in with a PC no problem).
Any update on when a new version is going to be released - Its getting really frustrating?

I figured out a solution that works you must disable Online Certificate Status Protocol (OCSP) on the affected system. To do this :
    Open Keychain Access. Keychain Access can be found by selecting Go in the Finder and choosing the Utilities option. Keychain access should be listed in the folder that appears. Double-click the Keychain Access icon to open it.
    Select Keychain Access -> Preferences from the menu at the top of the screen
    Choose the Certificates tab
    Change the OCSP option from Best Effort to Off
    Close the Preferences dialog and quit Keychain Access
    You should be able to NAC now

Getting the NAC agent out of the system tray.

I am installing a NAC solution for a customer and they don't want users to have the NAC agent in the sytem tray. Is there any way to do this because they are pretty adamant about it.

Hi,
Currently this isn't possible. If you have an account team, please ping them to get this added to the feature request list.

NAC Agent takes long time to run

Cisco NAC agent takes long time to popup or run on Windows 7 machine.
The client machine is windows 7, running nac agent 4.9.0.42, against ISE 1.1.1
Any ideas how to reduce NAC Agent timing?

Hi Tariq,
I'm facing the same issue with ISE 1.1.1 (268) with Agent 4.9.0.47 for Windows XP clients. I have already configured "yes" to disabled the l3 swiss delay and reduced the httpa discovery timer from 30 to 05 sec but still clients get aprox 2.30 minutes to popup and finished the posture discovery.
Can you please advise if this is the minimum time or what is the minimum time and what are the parameters to set to a minimum time to complete agent popup and posture discovery..?
Is there any option that we can run this on backgroup..?
thanks in advance..

NAC Agent reporting never shows a failure

I seem to only get reports for successful agent logins under Device MGMT>Clean Access>Clean Access Agent>Reports. Am I missing a setting somewhere? Even though I have had many failures (testing, etc) I never see a failed report. Any ideas?

Hello,
Could you please confirm what error message you are getting on the NAC agent (if using the NAC agent for posture validation)? The NAC agent will display the standard stuff such as 'temporary access', etc. The message displayed is based upon which requirement is failing, for example a standard AV installation check/rule.
Also, for this failing client, do you see a passed report or no report at all? Well, for the agents that ultimately pass posture assessment (even if a particular check/rule fails) we see a passed report. If the agent never gains access, IE never gets out of 'Temporary Access' we don't see any report. I am hoping that when a Agent fails posture assessment we will see a failed report. IE, we need a way for the service desk to be able to monitor failed sessions proactively, and with the minimal external alerts available (no email, etc) these failed reports would be key.
If we can't see no report at all, there may be something that breaks before that. I have pages and pages of successful reports, but not a single failed report.
A quick way to verify would be to collect the NAC agent's logs after a failure, under
Start > Program Files > Cisco > Client Utilities > Cisco Log Packager I don't see this installed on any of the machines with an agent? Please adivse where I can download it. Thanks.

ISE 1.2 nac agent provision

Hi,
Is there any way to do a nac agent auto provision?
I know it can be achieve by cwa portal(web redirect) and user have to install nac agent manually. But we would like to see nac agent be installed right afeter user successfully login using 802.1x.

I dont follow your thought process but this is how i have most of my deployments are setup.
CWA < NSP < COA < 802.1x < Posture Status Unknown *In this state either client does or doesnt have nac agent in which ISE will proceed to install it or continue probing to for the NAC agent.
Remove CWA < NSP < COA from the picture and you have your exact scenario. What is your work flow look like that it is not "automatic" and define what you mean by "manually"?

NAC Agent and NSP provisioning with ISE 1.1.1

I am trying to get all workstations (OSX and Windows) to install both the Native Supplicant Wizard and NAC Agent during the On-boarding process.
I am currently using the default guest portal in ISE.
The environment has been setup using a Dual SSID design.
At the moment, devices can connect to the provisioning SSID and get CWA. Device registration works, the portal runs the NSP setup which correctly sets up the network adapter.
The problem is the portal never attempts to install the NAC Agent.
The client provisioning policy has a separate policies for wireless/wired as well as OS. Each policy applies both a NSP and NAC Agent configuration. It appears the guest portal only checks the NSP configuration and not the NAC Agent config.
Any ideas?

Just so i understand this correctly you are using both a client provisioning portal and a native supplicant provisoning portal tied into seperate authz policies.
With that out of the way are you checking to see if the client is compliant in the client provisioning portal policy.
Let me know if you have the following configured (example windows OS), this is assuming that the endpoint is statically assigned to RegisteredDevices after native suppliant provisioning.
Rule 0 (endpoint group = RegisteredDevice) AND (AD:Domain user and authentication method:x509 and posturestatus:COMPLIANT) = Permit Access
Rule 1 (endpoint group = RegisteredDevice) AND (AD:domain user AND authentication method:x509[if you deployed certs in the native supp condition] AND workstation NOT EQUAL:COMPLIANT) RESULT client provisioning portal.
Rule 2 (endpoint group = Workstation) AND (AD:Domain User AND authentication mehod using mschapv2) RESULT windows provisioning portal
Hope that helps,

ISE and NAC Agent

Hello, we currently run NAC for our wired (OOB), wireless (IB) and VPN (IB) enviroments. We are looking at migrating over to ISE for our wireless enviroment as a first step, with follow-up projects to move the VPN and wired clients over. I have been reading that ISE will still use the NAC agent. Our current NAC enviroment is at 4.7.2 and we are running the 4.7.2.10 agent. We do not want to upgrade this enviroment, we would rather focus on migrating to ISE. So our thought was to upgrade the clients to the latest NAC agent version 4.9.1.5. This agent is supported against the 4.7.2 NAC Manager. The problem is, I do not see this agent version listed as supported in the ISE compatibility matrix. Instead, they list a NAC agent of 4.9.0.37, which ironically, is NOT listed in the NAC compatiblity matrix. So what version of NAC agent should we run in a mixed enviroment? I am hoping 4.9.1.5 is supported against ISE, and the matrix is simply not updated yet. Thank you in advance for your help.

Not sure I understand. The 4.9.1.5 NAC agent does run against our CAM, as we have tested that and it is listed in the support matrix. So if we upgrade our NAC applainces, we would still run that agent. Does that agent tun against ISE, and if not, what is Cisco's recommendation to bring ISE into the enviroment? We have to have a migration path, and wireless seemed like a logical first step. But we need a NAC agent that will work against Clean Access AND ISE as our laptops will be wireless and wired at different times. Which Agent would be recommended?

ISE nac Agent automatic upgrade possible ?

Hello all,
I have this :
802.1x windows with NacAgent version (let's say 1) <----> 802.1x Enabled Switch (aaa radius OK) <------> ISE and AD on the same LAN
ISE is configured for client provisionning with material (NacAgent version 2) downloaded from Cisco website (as depicted in the documentation)
I've a basic authentication and authorization scheme that let me in properly but I expect the NACAgent to be upgraded.
No profiling is configured for the time being.
Is anybody can help ?
Best regards ?

Hi Tarik,
Your are right regarding that option "upgrade is mandatory"
However, my case was that you do need to enter the ISE's FQDN on the NAC Client and make sure that DNS operates properly.
Once authenticated, the NAC agent shows an upgrade message.
It works.
Thank you all.
