Help with 4506 802.1x Port Based Authentication (Wired)

Hi all,
I'm trying to configure wired 802.1x security on a Catalyst 4506 IOS 12.1.19(EW), using Microsoft IAS (Microsoft's RADIUS), and Windows 2000 SP4 clients.
I've followed the procedures in the 4506 Software configuration guide and they seem to be straight forward.
I then turn 802.1x Debugging on the switch to monitor the 802.1x traffic, but there is none. If I bring the configured interface down and then back up, I do get some status change, but it seems like the switch is not sending or receiving EAPOL frames.
I then execute the dot1x "initialize" and also tried the "re-authenticate" commands, but I get an error saying that FastEthernet 2/2 is not a valid dot1x interface. The line card model number is WS-X4148-RJ21. Is the card not 802.1x compatible?
The switch does not throw any errors when I configure FastEthernet 2/2 as a 802.1x port by executing
dot1x port-control auto
i've also configured the interface to be a plain L2 access port by executing
switchport mode access
any help will be appreciated!

I am currently trying to get 802.1x port authentication working on a Cat3550 against Win2003 IAS but the IAS log shows a invalid message-authenticator error. The 3550 just shows failed. When I authenticate against Cisco ACS (by simply changing the radius-server) it works perfectly.
However, I am successfully using IAS to authenticate WPA users on AP1210s so RADIUS appears to be OK working OK.
Are there special attributes that need to be configured on the switch or IAS?

802.1X Port Based Authentication - IP Phone- MDA - Port Security Violation

I have configured 802.1X authentication on selected ports of a Cisco Catalyst 2960S with Micorsoft NPS Radius authentication on a test LAN. I have tested the authentication with a windows XP laptop, a windows 7 laptop with 802.1X, eap-tls authentication and a Mitel 5330 IP Phone using EAP-MD5 aithentication. All the above devices work with with the MS NPS server. However in MDA mode when the 802.1x compliant windows 7 laptop is connected to the already authenticated Mitel IP Phone, the port experiences a security violation and the goes into error sdisable mode.

I believe , you need to configure re-authentication on this switch port:
! Enable re-authentication
authentication periodic
! Enable re-authentication via RADIUS Session-Timeout
authentication timer reauthenticate server

IEEE 802.1x Port based Authentication with Restricted VLAN

Hi all,
I have the following configuration:
aaa new-model
aaa authentication dot1x default group radius
aaa authorization exec default local
dot1x system-auth-control
radius-server host 10.10.10.10 key cisco
interface FastEthernet0/1
switchport mode access
authentication event fail retry 1 action authorize vlan 2
authentication port-control auto
dot1x pae authenticator
spanning-tree portfast
But it takes quite a while for the user who is not authorized to be switch to vlan 2.
I would like to know what is best practice when using this kind of configuration and if it is possible to optimize on how long it takes to switch the unauthorized user to the restricted VLAN?
Regards,
Laurent

Laurent,
Based on your configuration it looks as if it will take one retry attempt before the client is placed in vlan2. Try to remove the 'retry 1' from command and see if that speeds up the time. Also take the output of the 'show authentication sessions interface '. Please post the output of the 'debug radius authentication' as that will help to see how long it is taking the radius server to respond.
thanks,
Tarik Admani

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.
Regards,
Federico

802.1x mac based authentication

We have Cisco ACS 3.3 is there a way to do authentication based on mac address, instead of username and password? We are looking to stop things such as user purchased access points and what not. Any info would be great.

Yes you are right, I misunderstood you. I was under the impression that you were talking about doing MAC based authentication on your AP's, not the switches. That is why I made mention to port security.
The 2 options would be standard port security or 802.1x port security if you switches support this.
In order to use the 802.1X port security, your switch would need to support it and the clients connecting to the switch would require a supplicant (EAP-TLS, EAP-TTLS, etc) in order for them to work, not by MAC address alone.
You can configure standard port security on the switch which will accomplish your intentions and not even need to use the ACS server.

Considerations for 802.1x Port Based and Wi-Fi Certificate Authentication

Lately, we have been going back and for with the thought of doing certificate authentication for Wi-Fi and Port. We have Server 2012 PKI and CA and it seems fairly straight forward to pump out a certificate to a user and have them authenticate with their
certificate to a RADIUS/NPS. However, every time I mention our thoughts with consultants or others they seem to cringe saying that they've seen this deployment cripple networks.
We have almost 50 branch retail locations (with hub-spoke topology - all have VPN tunnels to corporate and also a disaster recovery location) and their internet isn't always super stable and they absolutely need to have network access at all times because
they are running Point Of Sale. Right now, if their internet fails, they can remain functional because we have the necessary pieces at all locations to keep a Windows network going but I'm afraid that if we force 802.1x certificate authentication for the switch
ports and Wi-Fi that if their internet goes down, they won't be able to authenticate since the authentication server will be at corporate. I am curious as to how people deal with:
1. Fail over to a disaster recovery authentication server if Corporate connection goes down
and:
2. If internet fails locally and can no longer communicate with any authentication server. Is there some sort of scale-out? It seems complicated since (if I'm not mistaken) it needs access to the CRL to validate certificates and also a Network Policy Server
for the authentication and so on.
What we're really trying to accomplish is to prevent people from bringing in a laptop or device with an Ethernet port and removing an existing device and plugging into the port in its place. MAC filtering doesn't seem like a good solution on a large scale,
nor a super secure option so it seemed like 802.1x certificate seemed to be the most flexible without having to go full NAP/NAC. Anyhow, sorry for the lengthy post and I really appreciate your time in advance!

Re-authentication could be triggered by the NPS, the switch / AP or the client:
NPS: There is a bunch of attributes to be configured in the Network Policy that determine the time a machine can remain connected such as Idle Timeout and Session Timeout. (When WEP was still common the session timeout had been used to enforce
a change of the insecure key.) Otherwise, the machine should remain connected as far as NPS is concerned.
Switch / AP: Depends on the configuration, e.g. re-authentication has to be triggered if the link went down. If a user plugs a cable or accidentally disable WLAN on his machine when the internet link he will not be able to reconnect.
Then I have seen some options similar to the NPS options, and switches could have their own session timeouts or be configured for respecting the radius server's setting.
Client: The term "re-authentication" is also used happens if you have to / want to use both machine and user authentication: When the machine starts up, the machine account is authenticated; when the user logs on the user is authenticated;
when the user logs off the machine is authenticated again. Per GPO you configure the machines for this kind of re-authentication (the default) or use machine-only or user-only authentication instead.
It might be a challenge to manage and test these settings if you have to support many different APs / switches and different WLAN devices.
I would recommend to carefully test it with a pilot group of users.
Would you have any chance to turn off 802.1x on the switches / APs in case of a major outage? I guess not as you would be able to manage them remotely?

802.1x Machine Based Authentication - Password expired

Hi,
I would like to ask 1 question about machine based authentication on 802.1x.
1.We are deploying 802.1x on wired user.
2.Some user are using machine based authentication in order to authenticate their port.
3.However, after the user password expired, the user need to change their password and then the machine are unable to authenticate. The error i got is "External DB user invalid or bad password". Then switch assign the user to Guest Vlan
4.But, once i plug out the cable and plug in back the UTP cable after the user login, the switch will assigned the user to proper VLAN.
5.User wont be able to access their share drive n etc since the guest vlan only have access to the internet.
5.Anyone have any idea what is happening? It seems that the machine is sending the old password during authentication process to the ACS.
Anybody can shed a light to me. Thanks.

This should certainly work with that rev. On your passed (or failed) auth log, you should see the username of the session authenticating. If you see the FQDN of the machine, this is a machine auth. Also, machine-auth typically executes before the GINA is displayed to the user. It sounds like machine-auth is failing and we need to determine why. Has this machine been away from the domain for long?
This also might help:

It seems that the radius packet that the AP receive is not what is expected. Do not know if the problem is with the client or with the AP configuration. Try many things but running out of ideas. Any suggestions would be welcome

Help with file uploader, php script, Windows Authentication

I am trying to setup a really basic web-based file uploader that I will expand upon later. I have the flex application working well enough (very basic). However, I have a php script in a secure folder using windows authentication. When I try to send the file to the script, it doesn't seem to like my credentials, and refuses to do anything. I do not get an error message; just nothing happens.
My questions are:
Does anybody know where I should've looked before posting this thread?
Do I even have PHP set up correctly? (At first I just made a txt file and put a .php extension on it, then I tried to setup PHP on the server, but it was a little confusing for me)
Is Windows Authentication the problem?
I do plan on implementing SQL Server in the future (to keep track of Files and user-defined attributes for files), but I do not want to store the files in SQLserver, just their pathnames.
Is there a simple way to use ColdFusion (for free) to acheive this end?
I am somewhat experienced at coding applications, but am totally new to server-side scripts.
This is my php script:
<?php
$tempFile = $_FILES['Filedata']['tmp_name'];
$fileName = $_FILES['Filedata']['name'];
$fileSize = $_FILES['Filedata']['size'];
move_uploaded_file($tempFile, "./" . $fileName);

Help with internet cam and ports

I have a Linksys WVC54GCA wireless Internet cam. I have set the IP to a static address. Created a DDNs account and have the address. I can see the site/cam on any computer on my network but cant seem to get it to port forward out . Help from anyone would be great. Thanks

That is strange, because.
Earlier when you posted what your domain was, I went to http://network-tools.com/
and entered that domain name, you where ping-able / traceroute-able / I could find out the correct public IP and ISP address behind that domain.
But now, I can not see the correct IP address.
Now I am starting to wonder about what is going on..
I think know what was going on, why you could not connect to your self by public IP.
Auth failed, solve that first. Then I will tell you what to do..
That means...
While I don't use the same DDNS provider: Make sure that, you:
#1 Are not running any DDNS client on the computer too. That, I, suspect will cause that issue.
Run the DDNS client either on the router (if the router supports it) or on a computer behind that router.
#2 You enter in the correct user name and password ( "password" is not the same as "Password" )

I have the calculator working but I am having trouble figuring out thow to do a square root function, nth factorial, absolute value, and Fibonacci. java.lang.Math.sqrt()
nothing for factorial - write your own.

802.1x port authentication not working

I am having some troubles figuring out what is going on here. I am trying to setup 802.1x port based authentication to assign clients to VLANs. I inherited this mess and its been a long time since I have used this. I ran a wireshark on my Radius server and I see no packets even coming from my switch IP address when I plug into a port (I verified communication because pings come up in my trace)
Switch info:
sw-ConfB>sho ver
Cisco IOS Software, C2960C Software (C2960c405-UNIVERSALK9-M), Version 12.2(55)EX3, RELEASE SOFTWARE (fc2)
Port config:
interface FastEthernet0/11
switchport mode access
authentication event fail action authorize vlan 900
authentication event no-response action authorize vlan 900
authentication port-control auto
dot1x pae authenticator
dot1x timeout tx-period 5
Radius Server Info:
radius-server host 10.0.1.52 auth-port 1645 acct-port 1646 key 802.1x!
Kinda lost why not Radius packet even comes from the switch. Any tips?
