Problem of the NAC - Agent is a disconnect

Hello

We have a problem with the NAC in mode virtual outofband.

AD SSO, sanitation, everything is working, but the strange things happening: after awhile, when downloading large files, Agent connects to the formula of network users, and the registration process is restarted.

I disabled the pulsation clocks and timers, session, but we still have a problem.

Also, while sniffing traffic on the switch port, I noticed that after have correctly connected you to the own Cisco Agent network always send traffic to UDP Port 8905. Is this a normal behavior?

I noticed problems with this version of the agent causing connections to give up intermittently. I would upgrade to agent v4.1.3.1.

  • Problem of the NAC in the virtual tape gateway VPN SSO

    Hello

    I've implemented a NAC solution for remote users. The unit of CASE mode configured in the gateway enVirtual Strip.

    I followed all the steps listed in http://www.cisco.com/en/US/products/ps6128/products_configuration_example09186a008074d641.shtml

    Remote users can connect succeffuly using the cisco vpn software and they can ping the SIN, but not the DNS (the ASA offers IP @ but not the DNS I do not know why).

    When I access the NAS, I can download the NAC Agent but VPN SSO is not executed and the Agent asks me to connect using LOCAL DB.

    Any help please,.

    Kind regards

    Larson,

    For VPN SSO work, you must send the accounting package to the CAs. The CASE can in turn send for the ACS if you need accounting also be done on GBA, but for authentication ONLY work, the accountant must reach the CASE.

  • ISE - profile of the NAC agent

    Dears

    I want to deploy via GPO NAC agent and I need to create the agent profile, I know how to create on ISE, but how to get the file in xml format which will be distributed?

    You can try to install only a single PC (whether by a manual installation or captive portal). If you have set up rules of posture while ISE then the NAC Agent automatically contacts the ISE server and downloads the last NACAgentcfg.xml.

    Then you can browse the following directory and find the NACAgentcfg.xml file in your PC.

    C:\Program Files (x 86) \Cisco\Cisco NAC Agent

    After that, you can deploy mass agent of the NAC as well as the xml file. Well that is not required to deploy the xml file as a I said, every time, there is a rule of posture the NAC agent will download the last available the ISE Server NACAgentcfg.xml.

    Please rate if this can help.

  • Problem of the NAC plugins & Nessus

    Hi all!

    I have a problem with the installation of the Nessus plugin. ((

    After reading Installation Guides I have not a clear understanding what files should I download. So I have 2 files:

    Nessus-plugins - 2.2.10.tar.gz (6507 KB)

    Nessus-plugins-GPL - 2.2.10.tar.gz (1071 KB)

    of http://www.nessus.org/download/index.php

    After renaming, I tried to download each of them turning the cam under updates of the Plugin. CAM said "Upload successful" and has always some plugins (Scan Setup-> Plugins).

    So I don't understand what the problem... ((

    Can someone share file plugins.tar.gz correct, please...?

    Concerning

    You must download and install the Nessus appropriate for your PC.

    After downloading the latest plugins on the site of Nessus, in the directory (for a Windows installation) c:/Program Files / sustainable / Nessus / Plugins, you will have a file 'plugin.tar.gz '. You can rename or copy this into "plugins.tar.gz".

    Then in the console the NAC Manager, under ACCESS OWN-> NETWORK SCANNER-> Plugin updates, go to the same folder and choose the file "plugins.tar.gz". It MUST be named exactly as described - with the S - to work. Complete the DOWNLOAD. When finished go to the Configuration of Scan tab and select all in the show _ Plugins dropdown. You should hae about 20,000 of them.

    HTH.

    I have this:

    802.1 x-window with the NacAgent version (say 1) <---->802. 1 x switch active (RADIUS aaa OK) <------>ISE and AD on the same LAN

    ISE is configured for client provisioning with hardware (NacAgent version 2) downloaded from Cisco's Web site (as described in the documentation)

    I have a basic plan of authentication and authorization that allow me to well but I expect the NACAgent to be upgraded.

    No profiling is configured at the moment.

    Is that someone can help?

    Best regards?

    Hello

    In the ISE settings provisioning client, activate you the option where the NAC upgrade agent is required. However, it is to you to run updates perioidic and map the most recent agent in the configuration of the parameters of the client.

  • NAC agent the wireless runs whenever we have controllers

    Hello everyone, we have a problem in our environment and wanted to inquire about this. We have a Cisco wireless infrastructure in place - 5508 2 controllers and about 200 3502 AP we have split the AP evenly between 2 controllers. We backend system with an own server in the strip of the NAC device for post assesment. What we are seeing, is that when a user "passes" a point of access to the other, and if the AP is connected to 2 separate controllers, the NAC agent will take place once again. Newspapers in cam supports this, as we see the user is disconnected and then reconnected. We have 2 controllers configured in a mobility group which should allow roaming. So what would be the expected behavior? Is the controller always send RADIUS Accounting Stop packets to the CAs when it tends a session wireless to another controller, even if they are in a group of mobility?  Any help or thoughts would be appreciated.

    Thank you

    The f

    Jeff,

    Since you're using dot1x, I found the following note in the configuration guide for mobility:

    http://www.Cisco.com/en/us/docs/wireless/controller/7.2/configuration/guide/cg_mobility.html

    All clients configured with 802. full authentication is complete by 1 security X/Wi-Fi Protected Access (WPA) to conform to the IEEE standard.

    Your radius server that you see a second authentication attempt from the second controller? If Yes, then most likely, this is because of the management of accounts radius stop and start messages while roaming.

    Thank you

  • Question commissioning of the ISE NAC agent

    I downloaded the NAC agents and modules of conformity to the ISE and configured the client provisioning rules. The user guide is not really explain very good next steps.

    I guess because the identity of the user groups are used in politics, commissioning is used with webauth, is that correct?

    Jeppe,

    The commissioning customer is done with any authentication method. Whether via dot1x or webauth, it is the authorization policy that starts this process. You redirect your customers customer provisioning portal using the authorization policy. Then, you determine which agent (web agent, agent nac or no agent) through the client provisioning policy.

    Hope that helps,

  • NAC agent constantly authenticate

    I have a problem with NAC 4.9.4.3 where he réauthentifie randomly. There is no newspaper on the switch or within ISE to explain why this happens. The user seems to remain connected. Did somebody encounter this problem?

    Hi Deirra,

    How many times do you see that? You experience this problem with all the endpoints?

    If you don't see the newspaper on the ISE/switch so maybe not pure new authentication. The question may be followed by looking at the NAC agent logs.
