Network IEEE 802.1X problems

I bought a new macbook at last week and when I tried to conect on my university wireless lan with WEP IEEE 802.1X using TTLS.
In fact the conection works for 5 seconds... After it, my macbook starts an autentication process and cannot authenticate with the LAN. This problems happens by Wireless and by cable. In fact many other students are having the same problem but only with Macbook core2duo models. The old coreduo Macbooks works fine. So, it seems to me that this new model has a problem. I hope Apple find a way to solve it!!
macbook core2duo black Mac OS X (10.4.8)

Hi materdei,
I am having the same problem. The thing is though sometimes I stay connected without any problems for hours, but when then it disconnects if you don't "cancel" the authentication process, it just freezes there.
By the way I don't think it's just new Macbooks, it is all of them because I have an old Macbook, it doesn't work fine either, and I know other people with old Macbooks having the same problem. But for example I have never seen older Apple computers experiencing this.
Just thought it could be the uni's problem, but then why just Macbooks are affected?
ps: I see that you're from Portugal, and are you also studying there? Because I am having this problem in a uni in Portugal and I am not really sure but i think all the uni's are using the same system over there.

IEEE 802.1ad / 0x88a8

I have moved to another vendor at my edge, and I have continued to use 0x8100 as my ethertype which seems to play nice except for when a customer has a native vlan1 setup.
Vlan1 will get tagged into my SVLAN 301, but Cisco sees it as an incorrect BPDU, and shuts down the port. I also see customer CDP neighbor information, and other stuff when the customer doesnt prune his network down, or uses vlan1 on transparent lan services.
My new vendor told me to use the IEEE 802.1ad standard for the outter tag, (ethertype 0x88a8), but Cisco doesnt support it. Does anyone know why Cisco is not following the IEEE 802.1ad standard for provider bridges (Q-Q) tagging on the ME3400 series? I know they developed their own proprietary GBPT protocol for handling of L2 protocols but that doesnt help me now.
Just some quick searching, shows that the 7600 is supported with 12.2SR. ME3400's are not, its a 'future' release, but I dont know how long ago that document was written.

Currently, the default ether type is 0x8100 on a Cisco 7600 for the Q-in-Q outer tag. However, a few non-Cisco vendors use 0x9100 or 0x9200 ether type for the Q-in-Q outer tag. For Cisco 7600 router to operate seamlessly with other vendors it is required to provide a mechanism to change the default ethertype.
Moreover, there is a need to support ethertype 0x88A8 to support provider bridge defined by IEEE 802.1ad. Custom ethertype feature is proposed as a solution for this problem that enable change of ethertype as per requirements. Under the custom ethertype model, ethertype 0x9100, 0x9200 and 0x88A8 can be configured using "dot1q tunneling" CLI under a physical port.

Protocol version of IEEE 802.1x

Hi,Sir.
I ask question of dot1x's protocol version.
I want to configure version 1 of IEEE802.1x.
But, defaut version is 2 from IOS 12.2(25)SEE.
Could you tell me, how to configure for version 1 fo IEEE 802.1x.
(I use WS-C2950G-48TC-L)
Ryusuke

Hi,
Our network is design for version 1 of IEEE 802.1X.
We have some Catalyst switch.
WS-C2970G-24TS-E
WS-C3560G-48TS-S
These are running IOS at 12.2(25)SEC.
(This protocol version of IEEE 802.1X is 1)
I can't anthenticate when WS-C2960G-48TC-L is running IOS 12.2(40)SE.
(This protocol viersion of IEEE 802.1X is 2)
I can't authenticate when WS-C3560G-48TS-S is running IOS at 12.2(40)SE.
But I can authenticate when WS-C3560G-48TS-S is running IOS at 12.2(25)SEC.
(These are same configuration)
I think this problem is version 2 of IEEE 802.1X.
(My configuration for version 1 of IEEE 802.1X)
I want to resolve this problem.
Best regards.

Time Capsule (SIM) expand network with 802.11b/g Airport Extreme

Hi, I try to expand a Airport-Network which is set up with a Time Capsule (SIM (latest model). I like to use an Airport-Extreme-Basestation to expand the network. The two devices will be connected wireless. In the helpfile there is a explantation how to do this with 802.11n-devices but when it comes to the 802.11b/g-devices it just says I should have a look on the apple support-pages. I do not find anything there.
I tried everything, but it did not work. I've had a Time Capsule (first model) which died some days ago (the well known powersupply problem). With this Time Capsule I did not had any problems to set up a WDS.
What to do?

Of course I've already tried this and the other automatics, but it did not work. That is the reason I am asking for help. So I guess I need special settings.
NOT good !
No protection is not good, ok. But I want it to set up and running and after this I can switch on protection to eleminate some mistake-reasons.
WDS-Mode: "remote WDS-Basestation"
when the UFO joins the TC's network this will no longer apply
But this menu exists and the UFO does not join the network, so I have to select any of this settings!
try these steps provided by Tesserax:
Setting Up Time Capsule as a Second Wireless Router
802.11g AirPort Extreme Base Station -> 802.11n Time Capsule
With "mixed" AirPorts, you will need to configure both routers into a Wireless Distribution System (WDS). Your neighbor's AirPort Extreme Base Station (AEBS) will be the main and your Time Capsule (TC) will be the remote base station in this WDS.
To simplify setup, you should connect your TC directly to the AirPort's LAN port by Ethernet. Once the WDS is configured, you can disconnect the TC and place it at the desired location.
The following are the basic configuration steps to create a WDS:
(Note: To facilitate the WDS set up, jot down the AirPort IDs (MAC addresses) for each of the base stations to be used in the WDS. The AirPort ID and is printed on the label on the bottom/side of the base station.)
Main Base Station Setup - AEBS
o Click the AirPort status menu in the menu bar and choose the wireless network created by the base station you want to set up as the main base station.
o Open AirPort Utility (located in the Utilities folder in the Applications folder on a Macintosh computer, or in Start > All Programs > AirPort on a computer using Windows).
o Select the main base station, and choose Manual Setup from the Base
Station menu, or double-click the base station to open the configuration in a separate window.
o Enter the base station password if necessary. If the base station is using the
default password of public, you will not be prompted for a password.
o Click Wireless in the toolbar, and then choose “Participate in a WDS network” from the Wireless Mode pop-up menu.
o Click WDS and then choose “WDS main” from the WDS Mode pop-up menu.
o Select the “Allow wireless clients” checkbox if you want client computer to connect to this base station.
o Click the Add "+" button and enter the AirPort ID of the base station you want to connect to this base station.
o Click Update to send the new settings to the base stations in the WDS.
Remote Base Station Setup - TC
o Click the AirPort status menu in the menu bar and choose the wireless network created by the base station you want to set up as a remote base station.
o Open AirPort Utility (in the Utilities folder in the Applications folder on a Macintosh computer, or in Start > All Programs > AirPort on a computer using Windows).
o Select the remote base station, and choose Manual Setup from the Base Station menu.
o Enter the base station password, if necessary. If the base station is using the default password of public, you will not be prompted for a password.
o Enter the same network password as the main base station, if necessary.
o Click AirPort in the toolbar and click Wireless. Choose “Participate in a WDS network” from the Wireless Mode pop-up menu, and choose the same channel as the main base station from the Channel pop-up menu.
o Click WDS and choose “WDS remote” from the pop-up menu.
o Enter the AirPort ID of the main base station in the WDS Main field.
o Click Update to transfer the settings to the base station.
(ref: Pages 42-46 of "Designing AirPort Networks.)
802.11n AirPort Extreme Base Station -> 802.11n Time Capsule
o Open AirPort Utility and select the base station that will connect to the Internet.
o Choose Manual Setup from the Base Station menu, or double-click the base station to open the configuration in a separate window. Enter the base station password if necessary.
o Click AirPort in the toolbar, and then click Wireless.
o Choose “Create a wireless network” from the Wireless Mode pop-up menu, and then select the “Allow this network to be extended” checkbox.
o Next, select the base station that will extend this network, and choose Manual Setup from the Base Station menu, or double-click the base station to open its configuration in a separate window. Enter the base station password if necessary.
o Choose “Extend a wireless network” from the Wireless Mode pop-up menu, and then choose the network you want to extend from the Network Name pop-up menu.
o Enter the base station network and base station password is necessary.
o Click Update to update the base station with new network settings.
does this fix it for you ?

IEEE 802.1x Authentication with RADIUS failed

Hello guys,
I've a little strange Situation.
If user start his Computer (Windows 7 enterprise) and computer is connected via LAN it works fine.
If user start his Computer (Windows 7 enterprise) and computer is connected via WLAN it works also fine.
But if user start his Computer (Windows 7 enterprise) that is connected via LAN it is not more possible to connect to WLAN (parallel). I've implemented an IEEE 802.1 RADIUS authenticiation.
It does not work with this special user account. I've tested it already successful with couple other accounts.
Does someone has experience with such Situation?
Regards
Rodik

It does not work with this special user account. I've tested it already successful with couple other accounts.
Hi,
Did you mean that this problem just occures to the single User Account but others works fine at same computer, isn't it?
When it connect Wlan failed, is there any error message? Have you tried to reinstall the WLan device driver for test?
it would be better to provide more details about the Wlan connect failed.

How about joining IEEE 802.1X wired client to a AD domain ?

http://technet.microsoft.com/en-us/library/bb727033.aspx
This nice Technet link says clearly that there is three methods could be used for joining Wireless IEEE 802.1X client to a domain. Do these methods also apply for joining Wired IEEE 802.1X clients to a domain ?

Hi,
In some cases, routers or firewalls drop packets because they are configured to discard packets that require fragmentation.
Did you use NPS for authentication?
Follow this procedure to lower the maximum size that NPS uses for EAP payloads by adjusting the Framed-MTU attribute in a network policy.

Having trouble staying connected to IEEE 802.1X with my iPhone 4s

I got my iPhone 4S pre-ordered with Verizon and I am having trouble staying connected to my college's 802.1x WiFi connection. My college has a help website with a walkthrough to connect to the network and it works and I can get WiFi on my phone but when I lock my phone for about 1 minute my phone forgets the connection and I have to go through the steps all over again to get connected.
Here are the steps my school site has me follow:
Connecting to the RPI Wireless Network Using 802.1x Authentication on the iPhone / iPod Touch
Make sure that your device has been updated to the latest software version available.
Go into Settings and select Wi-Fi.
Make sure the Wi-Fi switch is set to ON.
Under Choose a Network, select Other....
Enter rpi_802.1x for the Network Name, and press the Security option.
Select WPA2 Enterprise as the security, then press the Other Network button in the top-left corner to return to the previous screen.
Enter your RCS userID and password in the appropriate fields and press the blue Join button in the bottom-right.
Let the network access load, then press the Accept button to accept the certificate provided.
This is really annoying so any help would be appreciated.

We use 802.1x Authentication here at UCSD and it seems fine.
The only problem i see is it will disconnect when you lock the phone but it automatically reconnects when you unlock the phone.
Our setup is a lot simpler, you just select the network and enter in your AD account information.
It could be your college has not setup their wifi correctly. You should connect your network team.

My wifi network is 802.11n but there are times changing for 802.11g, and have to restart ... after the update for Mountain Lion... Help!!!
Several problems with Mountain Lion, APP STORE (login/logout error), WIFI(802.11n for 802.11g), MAIL (horrible)... Apple, what is happening?

Do a factory reset .. nothing will be deleted from your backups and you will be able to get access to them again.
The Factory Reset Gen1-4.
Unplug your TC. Hold in reset. and power the TC back on.. without releasing reset for about 10sec. When the status light flashes rapidly; release it.
Be Gentle! Feel the switch click on. It has a positive feel.. add no more pressure after that.
TC will reboot after a couple of minutes with default factory settings and will wipe out previous configurations.
No files are deleted on the hard disk.. No reset of the TC deletes files.. to do that you use erase from the airport utility.

I have the new ipad retina however i connect it to the wifi at work the signal comes and goes, especially as soon as i use an app that requires wifi, my iphone 4s is connected to the same network with no such problems, why is my ipad giving me these probl

I have had my ipad retina for two and a half weeks but since the week end every time i connect to the wifi network it joins then disapears as soon as i open safari for example or just disappears at intermittent intervals....i have my iphone 4s connected to the same wifi network with no such problems.
I have tried resetting the network settings to no avail
Does anyone have any suggestions?
Many thanks in advanced.

IEEE 802.1x port-based authetication

I want to configure IEEE 802.1x port-based authentication on cisco switches, preferable 2960 series. Which models support this feature?. I have try with some older switches but it doesn't works properly on everyone.
I have upgraded them whitout better results, there is namely an issue with TLS handshaking on some switches which produces authentication to fail.

Hi Claudia,
do you mean that the EAP-TLS authentication fails only on some 2960 switches and it works on other 2960s?
What is the IOS version you're using there?
What is the RADIUS server in use?
What is the exact error message you see on the RADIUS side?
Usually, the reason for the EAP-TLS handshake failure is to be troubleshoot on the supplicant and AAA server, however, there may be something on the switch depending on the certificate size and MTU settings on the switch(es).
What is the server cert size and the MTU configured on the switches?
With the info you provided it's difficult to say what's the reason of this failure.
I would suggest to start looking into the above mentioned topics, else you would need to proceed with deeper debugging and sniffer traces, which may be better/easier to handle through a TAC case.
I hope this helps.

Federico

National Instruments PXI with IEEE 802.15.4 standard (ZigBee)

Bonjour,
En fait, je travaille sur un projet qui a pour but d’implémenter un émetteur/récepteur Zigbee en bande de base reconfigurable sur la plateforme d'évaluation XUPV5-LX110T qui embarque un Virtex 5. Je suis actuellement dans la phase de test réel.
Premièrement, Je veux envoyer mes données venant d’un pc vers un FPGA et de les recevoir (pour traiter mes signaux sur Matlab). Est-ce-que cette tâche est faisable ou non ? Y a-t-il une solution pour ça en utilisant un média de communication (la liaison série par exemple)
Deuxièmement, Y a-t-il un équipement de mesure et de test de National Instruments à l’aide des PXI qui supporte le protocole sans fil Zigbee ou autrement la norme IEEE 802.15.4 (à savoir RF Vector Signal Generator et Vector Signal Analyzer) de la partie frontale analogique que ce soit en émission ou en réception?
Et merci d’avance pour tout le monde.
Hello,
In fact, I'm working on a project which aims to implement a reconfigurable Zigbee tranceiver on XUPV5-LX110T Evaluation platform which integrates a Virtex 5 FPGA. I am currently in the phase of real test.
First, I want to send my data from a PC to FPGA and receive it (to treat my signals on Matlab). Is this possible or not? If yes, Is there a solution for it using a medium of communication (e.g. serial link)
Second, is there a measuring equipment and testing National Instruments using PXI which supports the Zigbee wireless protocol or otherwise IEEE 802.15.4 standard (i.e. RF Vector Signal Generator and Vector Signal Analyzer) of the analog front-end either in transmission or reception?
And thanks a lot in advance for everyone.

Hello,
I am not sure what data you will be collecting, or how you intend on using the board. Perhaps you can explain your application a little bit more?
Is the FPGA code already developed for your application with the XUPV5-LX110T board? As long as the developed FPGA code is able to communicate with your PC via whatever protocol you choose, then you can use that as a channel to send data back and forth. Since the board is capable of many different I/O connections, you can pretty much sending/receive data over which ever connection you prefer, Ethernet, RS-232, etc.
Just to clear up any confusion, if you do not already have FPGA code for the board, this is not something you would be able to develop with LabVIEW FPGA programming. The XUPV5-LX110T board is not supported for programming its FPGA using LabVIEW FPGA. You can however, program in labVIEW to communicate data back and forth with the I/O you have chosen to connect with to your PC, such as Ethernet or RS-232, as mentioned above.
As far as measuring equipment NI offers for testing with the Zibee (IEEE 802.15.4) wireless protocol in the PXI platform, if your application requires you to both transmit to, and received from the board, and then you would need either both a Vector Signal Generator and Vector Signal Analyzer, or a Vector Signal Transceiver. See the list below for some examples of what we have to offer.
VSAs: NI PXI-5661, NI PXIe-5663E
VSGs: NI PXI-5671, NI PXIe-5672/5673E
VSTs: NI PXIe-5644R/5645R/5646R
From my knowledge of ZigBee, you would be capable of communicating with the board using any of these devices.
