How to do .1x port based network access authentication through ACS

How to do .1x port based network access authentication through ACS.

Hi,
802.1x can authenticate hosts either through the username/password or either via the MAC address of the clients (PC's, Printers etc.). This process is called Agentless Network Access which can be done through Mac Auth Bypass.
In this process the 802.1x switchport would send the MAC address of the connected PC to the radius server for authentication. If the radius server has the MAC address in it's database, the authentication would be successful and the PC would be granted network access.
To check the configuration on the ACS 4.x, you can go to http://www.cisco.com/en/US/docs/net_mgmt/cisco_secure_access_control_server_for_windows/4.1/configuration/guide/noagent.html
To check the configuration on an ACS 5.x, you can go to http://www.cisco.com/c/en/us/td/docs/net_mgmt/cisco_secure_access_control_system/5-2/user/guide/acsuserguide/common_scenarios.html#wp1053005

  • How to setup 24 hours guest network access with Time Capsule 4th gen. ?

    Hello,
    I just bought a Time Capsule 2TB and I cannot find the setting to limit the network access to 24 hours.
    I updated the firmware and Airport Utility to the latest version and it seems that most of help on this setting I fond on internat are based on previous version.
    By example I do not have a "Manual setting" in the "Base Station" menu like described in the manual.
    Can someone help on this ?
    Thank you and Regards,
    Sebastien

    Suggest that you download and install AirPort Utility 5.6 for Mac OS X Lion. It will have the settings that you are looking for.
    You can keep both AirPort Utility 5.6 and 6.0 on your Mac and use the one that you need.

  • HT4262 How do I re-set my network access password?

    How do I re-set my network password?

    You simply set it via the airport utility.
    https://discussions.apple.com/message/21138326#21138326
    If you have forgotten the password, reset the Airport by doing a short press of the reset button.. this is called soft reset.. all passwords are set to factory for 5min so you can change them till your hearts content.. then upgrade the airport.

  • How can we allow internal users to access internet through ASA firewall?

    Hello,
    I am new to security track, i have been asked to setup lab and allow users from inside firewall to access internet. here is my lab setup
    PC -> switch 1 (layer2) -> (inside) ASA (outside) -> switch 2 (Layer2) -> Router
    does switch 2 port needs internet access through router?
    what configuration required on ASA to allow users behind the firewall to access internet?
    any help on this would be much appreciated.
    thanks,

    Hi,
    Okay , can you clarify on this for me. Are you able to ping the internet from the ASA outside interface ?
    Just try something like this:-
    ping 4.2.2.2 .. Does this work ?
    If this does not work , then i think the ASA even is not able to get to the internet and that would be a problem on the router.
    Also , internet from Switch 2 is not a requirement as that is only a Layer 2 device.
    You can assign the ISP allocated address on the PC , connect it to the Switch 2 port and then try to ping something on the internet or surf internet and i think that should work.
    Thanks and Regards,

    If you upgrade to JHeadstart 10.1.2.2 (requires a license), you will get built-in support for user authenrication and authorization including showing tabs based on the role. 10.1.2.2. ships with a demo app that uses all these features.

    Running 3.6.3. Bookmarks lost. Unable to find extensions in Add-Ons folder. Running Mac OS 10.4.11. Please advise.

  • "wake for network access" not working

    Hi guys,
    I enabled System Preferences > Energy saver > Wake for network access
    and
    System Preferences > Sharing > remote Login
    These are the exact settings I had under Snow Leopard and it used to wake my iMac via 5GHz WiFi. I use a AirPort Extreme and didn't change a thing on its side. But neither with VNC nor with my iPad app "Screens" I am able to wake it under Lion. Screens tells me "Computer in sleep mode"...
    Any help?
    Thanks in advance,
    Bado

    I've been having problems with wake for network access on Lion as well. Similarly to others, if my iMac has recently gone into sleep mode, then it will wake up for Apple TV use or for file and screen sharing from another computer. After an extended period of time, however, all such functionality disappears.
    I've been rooting around in System Profile and have found something that may be of interest. Under the Hardware section, in the Power menu, there is a parameter called 'PrioritizeNetworkReachabilityOverSleep'. On both my iMac and Macbook this is set to zero (i.e. 'no').
    Does anybody have any idea what it means? And if there is any way to change it? If I had to guess, it sounds as though there is a setting somewhere in the system configuration (thought apparently not visible from the GUI) that sets the computer to remain in sleep mode rather than briefly waking to maintain its registration with the relevant Bonjour sleep proxies.
    Hopefully we'll be able to get to the bottom of this, as over six months after Lion's release the problem has yet to be resolved by Apple through version updates, something that is especially frustrating given how excellent a feature wake on network access is when it can be reliably coupled with an Apple TV or Back to my Mac.

  • PIN-based guest access for airport express

    how do I setup PIN-based guest access for airport express?
    I have a 2010 iMac OS X 10.6.8 and an Airport Express of the same era.
    Thanx in advanced...
    Siegfried

    Hello Bob,
    Thank you for your time on this.  I apologize for not giving you a more complete picture of what was going on. 
    I should have included that I had already performed the steps that you shared and had gotten to the place where I would enter the PIN. 
    The problem was that, after entering a PIN that I had come up with, the "continue" button never became active.  I called Apple Care and ended up talking to 3 different people before I found someone that knew the answer.  The answer is that the guest computer (client) MUST be present inorder for me to complete the setup.  So, problem is now solved.  Thanx...

  • Unauthorised users accessing iviews through a direct URL

    Hi,
    How do you prevent unauthorised users from accessing iviews through a direct URL? e.g. From the BeX Web Template on testing a query a URL is known, this URL can then be used by user who have no rights to view/ execute this report (after portal logon).
    Can security zones be defined for the BeX iviews? If yes, how? Does setting the parameter Dcom.sap.nw.sz=true solve the problem? 
    Appreciate your input.
    Many thanks,
    Dharmi

    Hi Bharath,
    Thank you for the input.
    Can you please be more specific as to which BW component ?
    I navigated to
    Go to permission editor: 'System Administration' -> 'Permissions' -> 'Portal Permissions'.
    folder: 'Security Zones' -> 'sap.com' -> 'NetWeaver.Portal' -> 'high_safety'
    There the rights are ok.
    Best regards,

  • HT3576 how can i verify that the network or firewall is not blocking access to port 5223.

    how can i verify that the network or firewall is not blocking access to port 5223?

    Talk to someone who knows something about networking and/or firewalls on an appropriate forum.
    Configuring your network and/or firewall is beyond the scope of this forum, which is devoted to issues using the iPhone.

  • How do I open ports on my airport extreme and assign a fixed IP Address for a device connected to my network?

    I recently had a security system installed in my house.  One of the features is an EPAD which enables me to have a virtual keypad on my iphone, and computer to operate the alarm system.  The technician was not familiar with Mac's and Airports.  How do I open port 80 to 80 in my airport and assign a fixed IP address for the EPAD?  Apparently this is what is needed to make this work.

    There are three ranges of "strictly local" IP addresses reserved for local Network use:
    192.168.xxx.yyy
    172.16.xxx.yyy
    10.xxx.yyy.zzz
    What your Router does for you is to act as your agent on the Internet.Your requests are packaged up and forwarded on your behalf, and only when a response is expected is the response returned to your local IP address.
    Directing Network Traffic to a Specific Computer on Your
    Network (Port Mapping)
    AirPort Extreme uses Network Address Translation (NAT) to share a single IP address with the computers that join the AirPort Extreme network. To provide Internet access to several computers with one IP address, NAT assigns private IP addresses to each computer on the AirPort Extreme network, and then matches these addresses with port numbers. The wireless device creates a port-to-private IP address table entry when a computer on your AirPort (private) network sends a request for information to the Internet.
    If you’re using a web, AppleShare, or FTP server on your AirPort Extreme network, other computers initiate communication with your server. Because the Apple wireless device has no table entries for these requests, it has no way of directing the information to the appropriate computer on your AirPort network.
    To ensure that requests are properly routed to your web, AppleShare, or FTP server, you need to establish a permanent IP address for your server and provide inbound port mapping information to your Apple wireless device.
    To set up inbound port mapping:
    1) Open AirPort Utility, select your wireless device, and then choose Base Station > Manual Setup, or double-click the device icon to open its configuration in a separate window. Enter the password if necessary.
    2) Click the Advanced button, and then click Port Mapping.
    3) Click the Add button and choose a service, such as Personal File Sharing, from the Service pop-up menu.

  • How do i diagnose a network access error with Gracenote or other sites??

    Ok, this is not strictly itunes but here goes.
    Since i upgraded to 7.2 about 3 weeks ago, i have had only 50% success in accessing gracenote when i put a cd in (ie this morning around 10am no problem, now at 5pm can't get to it). My internet connection is AT&T DSL. It comes with a connection diagnosing tool which never says there is a problem, windows xp connection diagnosing tool says no problem, and yet there are certain websites i can now no longer get to not just gracenote via itunes. using ie or firefox i can't get to discussions.apple.com ironically (i can get to www.apple.com), so is gracenote, and occasionally the weather channel desktop, and yahoo email. i turned off all firewalls and there is no change. however. i then access my work vpn (via the at&t dsl connection, not dial up) and hey presto i can get to all these sites i couldn't before. so if i go through vpn i can always get to gracenote if i use native dsl connection i can't. i think at&T is preventing access through it's own network to parts of the web because of bandwidth issues ( i have emailed them and they say there is no problem in my area), but won't admit it, and i can't prove it. so my question is how do i prove where the network bottleneck is in accessing these sites since the tools i get say there is no problem??? or could it be a dns problem???
    plz if anyone can help offline i would be so happy, it is so frustrating not being able to load cd's into itunes whenever i feel like it.

    How did you set up chroot?
    FYI, you don't need to chroot to use pacman with a not root filesystem.
    man pacman wrote:-r, --root <path>
    Specify an alternative installation root (default is /). This should not be used as a way to install software into /usr/local instead of /usr. This option is used if you want to install a package on a temporary mounted partition that is "owned" by another system.  NOTE: if database path or logfile are not specified on either the command line or in pacman.conf(5), their default location will be inside this root path.
