About 802.1x port authentication using TACACS+

Hi
I have some question. Please help me. Thanks.
Question1. May I use that 802.1x port authentication using TACACS+
Question2. Is it true? TACACS+ will not work with 802.1x because EAP is not supported in TACACS+, and there are no plans to get EAP over TACACS+.
Any help would be greatly appreciated.
Thanks.

Thanks to you.
Where to find the documents about Tacacs+ doesn't support EAP?
I cast more time and I cannot find the documents.
Please help me....
Thanks.

Radius server for 802.1x port authentication

Does anybody know if CiscoSecure for Unix version 2.3.6.2 can be used as a Radius server for 802.1x port authentication? I know the Windows version will do this and can be configured to assign a user to a specific VLAN, but can the UNIX software do the same?
Thanks

Check connectivity between the PIX and the server.
If the server is outside the PIX, verify that it is specified in the (if_name) parameter of the aaa-server command. In the example below, the (if_name) parameter represents outside.
aaa-server group_tag (if_name) host server_ip key timeout 5
If you are using TACACS+, verify that the PIX and server are communicating on the same port (Transmission Control Protocol (TCP)/49).
If you are using RADIUS, verify that the PIX and server are communicating on User Datagram Protocol (UDP) port 1645. Or, if the RADIUS server is using port 1812, verify that the PIX is using software version 6.0 or later, and then issue the aaa-server radius-authport 1812 command to specify port 1812.
Ensure that the secret key is correct.
Check the server logs for failed attempts. All servers have some kind of logging function.

802.1x Port Authentication via RADIUS

I am investigating implementing 802.1x port authentication on our network.
I have a test LAN with a Catalyst 2950 switch and 2 Win XP workstations, (I know its pretty basic, but should be enough for testing purposes). One of these XP PCs is running a Win32 RADIUS server and the other has been configured for 802.1x authentication with MD5-Challenge. Both switch ports are configured for the default vlan and can ping each other.
I have configured the switch with the following commands
aaa new-model
aaa authentication dot1x default group radius
dot1x system-auth-control
radius-server host x.x.x.x key test
and the port to be authorised has been configured with
dot1x port-control auto
As far as I can tell this is all I need to configure on the switch, please correct me if I am wrong.
When I plug the PC into the port I get the request to enter login details, which I do, the RADIUS server sees the request but rejects it, because 'the password wasnt available'. Here is the output from the request, but there isnt any password field and I know there should be as the RADIUS server comes with a test utility and the output from that is similar to below, but the password field is included. I have removed IP/MAC addresses.

*Mar 2 01:58:38: dot1x-ev:Received VLAN Id -1
Again there doesnt appear to be a password, shouldn't I see one?
Ultimately we will be using a Unix RADIUS server but for testing purposes I have just configured an eval version of Clearbox's RADIUS server. I've tried others as I thought the problem maybe the software, but I get similar problems regardless. If anyone can recommend better Win32 software, please do so.
I'm struggling to figure out where the problem is, the XP machine, the switch or the RADIUS server. Any advice would be appreciated as it's getting quite frustrating.

These are dot1x event debugs, so you wouldn't see this with that debug. The closest thing to seeing it would be to debug radius on the switch, and the password would be contained in RADIUS Attribute[79]. The switch uses this attribute to replay the EAP message (unmodified) to a RADIUS server. You might see it, but it's encrytped, so it might not buy you much. I'm sure you can imagine from a security point of view why the switch won't/shouldn't have this much visibility into this ;-).
I would recommend either:
a) Double-checking your RADIUS setup and logs to find out why the user failed. (double-check the RADIUS key configured on the switch too .. it must match).
b) Downloading a third-party supplicant from Meetinghouse or Funk to use as a control.
Eval copies are available on their websites.
Hope this helps,

802.1x port authentication and Windows Radius, possible?

Hello,
I'm just testing at the moment before implementing on our netowrk, but has anyone implemented 802.1x port authentication on there Cisco switch and used a Windows IAS server? See out users are all all on a Windows domain and I want to authenticate using their active directory credentials. I think I am fine with the switch config, but it is the Windows IAS/Raduis server. I have added the switch IP's and secret, but I need to create a policy to accept the domain users and need help.
Thanks

Andy:
Yes of course you can use whatever radius server as a AAA server for 802.1x authentication on the switches. NPS, IAS, ACS, Open RADIUS ....etc.
If you have problem with configuring the IAS then I would suggest that you post your quesiton in a microsoft forum and not here. They would be able to better assist you with your issue. But you can still look somewhere in this forum or in google to help yourself.
See this link, it could be useful for you: https://supportforums.cisco.com/thread/2090403

Help Please :) LInksys WRVS4400N 802.1X port authentication setup

HI all,
I am trying to configure 802.1X port authentication on my Linksys WRVS4400N. I created a test lab in order to do this, currently I am using
1x Linksys WRVS4400N
1x Microsoft Server 2003 with IAS and Active Directory services
1x Dell Laptop (Used for testing Radius Athentication)
I Created 4 VLAN(s) to test with this LAB
VLAN 1 Managament. Addr Range 192.168.1.0 /24. GW 192.168.1.254
VLAN 10 Servers. Addr Range 172.16.1.0 /24. GW 172.16.1.254
VLAN 20 IT. Addr Range 172.16.2.0 /24. GW 172.16.2.254
VLAN 30 Design. Addr Range 172.16.3.0 /24. GW 172.16.3.254
This is how I assigned my VLAN(s) to my ports. This is found on the VLAN & Port Assignment Screen
Port 1 -> Mode: General -> Frame Type: All -> PVID 1 (Port 1 is used for VLAN 1: Management)
Port 2 -> Mode: General -> Frame Type: All -> PVID 10 (Port 2 is used for VLAN 20: Servers)
Port 3 -> Mode: Access -> Frame Type: All (Port 3 is used for RADIUS. DHCP enabled)
Port 4 -> Mode: Access -> Frame Type: All (Port 4 is used for RADIUS. DHCP enabled)
VLAN 1: Default
Port 1: Untagged, Port 2: Tagged, Port(s): 3, 4 & Wireless: Excluded
VLAN 10: Servers
Port(s): 1, 3, 4 & Wireless: Excluded. Port 2: Untagged
VLAN 20: IT
Port(s): 1, 2: Excluded, Port(s): 3,4 & Wireless: Untagged
VLAN 30: Design
Port(s): 1, 2: Excluded, Port(s): 3,4 & Wireless: Untagged
This is how my Radius is setup
Mode: Enabled
RADIUS IP: 172.16.1.1 (IP of the WIN2K3 Server)
UDP Port: 1812
Secret: Password1
Port(s) 1 & 2: Force Authorized
Port(s) 3 & 4: Force UnAuthorized
On the Server this is what I have configured
1. Created a domain: GLAB. Created two groups: IT LAN, Design LAN, then assigned users to those groups. IE: User1 belongs to IT LAN
2. Created a IAS Remote Access Policy and named it IT LAN. The profile settings are listed below
Tunnel-Medium-Type: 802
Tunnel-PVT-Group-ID: 20
Tunnel-Type: Virtual LAN
My goal is to test RADIUS authentication on ports 3 and 4 on the Linksys WRV . I tested everything else I made sure the VLAN's were working ok so what I did was took a Dell Laptop and joined it to my domain. I pluged the Dell Laptop into port 4 to test Radius Authentication. When I tried to log in as User1 it didn't work.
I am new to setting up 802.1X, I wanted to know if I missed a setting or I misconfigured something. I even ran wireshark on my Windows 2003 machine to see if any RADIUS data is coming from my router (172.16.1.254) and I didn't see anything
If anybody can help me out that would be great!
Cheers
Graham

1. I don't think the WRVS4400N supports RADIUS assigned VLANs. I can't find anything in the manual suggesting it would. I would say you can only use the RADIUS server for authentication on a port but the VLAN must be configured before.
2. You don't write what is exactly connected to each port on the WRVS. For instance, it is unclear whether the MS Server is connected directly to port 2 or whether it connects to another switch to which you have connected other servers as well.
3. The VLAN configuration looks very odd to me. If I see it correctly you have:
Port 1: General mode, PVID 1, 1U
Port 2: General mode, PVID 10, 1T, 10U
Port 3: Access mode, PVID ???, 20U, 30U
Port 4: Access mode, PVID ???, 20U, 30U
I wonder why you are even able to set this up...
a. Port 1 should be set to Access mode with PVID 1 and 1U. With access mode the port is member of a single VLAN and all traffic is untagged. That is exactly what you have set up, but with General mode.
b. Port 2 must be connected to a server (or a managed switch). The NIC in the server must be configured for 802.1q tagged frames. On the server NIC you must configure VLAN 1 as tagged VLAN and VLAN 10 as default/native/untagged VLAN. Only then the server is able to communicate on VLAN 1 and VLAN 10.
c. Port 3&4 are in access mode. In access mode the port can only be member of a single VLAN. What you post suggests that they are member of two VLANs. That should not even be possible to configure. If it is possible, that it is definitively incorrect. You must decide to which VLAN these ports belong to.
4. To use RADIUS authentication on a port you must set it to "Auto". "Force UnAuthorized" sets it unauthorized, i.a.W. you disable the port completely. To traffic will go through. See the manual: "Force Unauthorized—Controlled port state is set to Force-Unauthorized (discard traffic). All connections are blocked."
5. Did you verify that your RADIUS server is actually using port 1812? 1645 is also commonly used for radius authentication. Check the configuration on the RADIUS server or check with "netstat -a" to see if 1812 is used.
6. Also check, whether the RADIUS traffic is sent on the management VLAN 1. The WRVS uses VLAN 1 as management VLAN and it might well be that it expects the RADIUS server to be in the management VLAN. Use the server IP address in VLAN 1 as RADIUS server IP address to check that.
7. Did you check with wireshark the traffic on the 802.1x client machine? Does it send something out? Does it receive anything?

FWSM: AAA authentication using TACACS and local authorization

Hi All,
In our setup, we are are having FWSMs running version 3.2.22 and users are authenticating using TACACS (running cisco ACS). We would like to give restricted access ( some show commands ) to couple of users to all devices. We do not want to use TACACS for command authorization.
We have created users on TACACS and not allowed "enable" access to them. I have also given those show commands locally on the firewall with privilege level 1. and enabled aaa authorization LOCAL
Now , those users can successfully login to devices and execute those show commands from priv level 1 except "sh access-list". I have specifically mentioned this
"privilege show level 1 mode exec command access-list" in the config.
Is there anything i am missing or is there any other way of doing it?
Thanks.

You cannot do what you are trying to do. For (default login you need to use the first policy matched.
you can diversify telnet/ssh with http by creating different aaa groups.
But still you will be loging in for telnet users (all of them) using one method.
I hope it is clear.

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:

Kinda lost why not Radius packet even comes from the switch. Any tips?

VPN Tunnel w/ 802.1X port authentication against remote RADIUS server

I have a Cisco 892 setup as a VPN client connecting to an ASA 5515-X. The tunnel works fine and comes up if theirs correct traffic. I have two RADIUS servers I want to use certificate based authentication to, that are located behind the ASA 5515-X.
If I connect a computer that has the correct certificates to ports FA0 through 3, authentication won't work. I'll see the following. This happens even if the VPN tunnel is established already by doing something such as connecting a VOIP phone. No entrys are located in the RADIUS logs, and I also cannot ping the RADIUS servers from VLAN10.
*Jan 30 19:46:01.435: %RADIUS-4-RADIUS_DEAD: RADIUS server 192.168.1.100:1812,1813 is not responding.
*Jan 30 19:46:01.435: %RADIUS-4-RADIUS_ALIVE: RADIUS server 192.168.1.100:1812,1813 is being marked alive.
*Jan 30 19:46:21.659: %RADIUS-4-RADIUS_DEAD: RADIUS server 192.168.26.10:1812,1813 is not responding.
*Jan 30 19:46:21.659: %RADIUS-4-RADIUS_ALIVE: RADIUS server 192.168.26.10:1812,1813 is being marked alive.
If I connect a second PC to an interface with 802.1X disabled, such as FA6, the VPN tunnel will establish itself correctly. In this situation, I can ping the RADIUS servers from VLAN10. If I go ahead and connect another PC with correct certificates to a port with 802.1X enabled such as port FA0 through 3, then 802.1X will suceed.

I have 802.1X certificate authentication enabled on the computers. As described in my post above, authentication will work if theirs another device on the same VLAN that is connected to a port that bypasses authentication. It seems like I have a chicken and egg scenario, a device needs to be sucessfully connected to VLAN10 before the router will use it's VLAN10 interface to communicate with my remote RADIUS server.

802.1X Port Authentication\ACS Question

Hello,
I"m troubleshooting a 3560 port authentication issue. From what I was told from other members of my team when we upgraded to windows 7 at this site authentication no longer works. I compared an old config to a recent one and noticed there was no command dot1x system-auth-control.
I have only been dealing with 802.1x for a short time and my other configs have this command. My question is without this command could there still have been port authentication working? On a inteface for ex. they do have the following which are inligned with my other configs. FYI, I didn't set this site up and it has the rest of the config correct like radius and aaa. When I went onsite to test I shut down the service on my laptop for 802.1x which should of blocked me so I thought. When I checked the ACS server for the log it showed my username and my correct IP address along with the correct switch but it showed I connected using PAP_ASCII, I"m not sure how this protocol got used since we don't use that. Thanks for any suggestions you might have.
dot1x pae authenticator
dot1x port-control auto
dot1x host-mode multi-host
dot1x violation-mode protect
dot1x reauthentication
aaa new-model
aaa authentication password-prompt PASSCODE---->
aaa authentication login default group radius local
aaa authorization exec default group radius local
aaa session-id common

I have a little more to add. I was looking in the ACS and did find PAP_ASCII checked so at my home office which I know port security to be working at least that's what I thought. I turned off wired auto config and could still get on and when I looked at the ACS logs I saw my name with this protocol again. Not sure how this got turned on but my questionbecomes if 802.1x is setup on the switch but ACS allows this protocol and my laptop isn't running any 802.1x settings I can still get on the network, is this the correct behavior for this setup?
Thanks,

WAAS Authentication using TACACS+

Hi,
I am trying to use TACACS as the primary method of authentication. The thing is that I configured in WAAS the values required (security word, primary server and secondary server). Also, in Authentication Method I chose TACACS as primary and local as the secondary.
After that I logged in to the WAAS using my TACACS account and I could enter, but the Navigation Pane is empty. It seems like my account doesn't have permissions to change config, but it is level 15 in TACACS ( I used to change config in Sw and routers).
I dont know if I am missing a step to config this feature either on the WAAS or the ACS.
Thanks,

TACACS really only provides a single "A" Authentication.
Are you allowed or not....
in order to provide Authorization, you need to still create the account in CM. and provide a role and domain in the user config.
Leave the Local user check box "unchecked" if you plane to use TACACS to Authenticate.
Im sure there is a way to provide authorization through complex custom attributes but it achieves the same goal via CM. once authenticated.

Aaa authentication using tacacs+ for LAP

WIth Autonomous AP, you can configure aaa authtentication using Tacacs+.
In lightweight AP, do u have similar function where u authenticate using tacacs+ when u telnet/ssh into the LAP after it is registered to the WLC?
Rgds
Eng Wee

There really isn't anything you can do on the LAP through telnet/ssh. You can enable TACACS for access to the controller.

802.1x wireless authentication using NPS - SSO sign on to Office 365 using ADFS

Hi Spiceys,I'm researching for a potential client and would like to know if the following is possible:They have an existing wireless network with a working 802.1x implementation using NPS as RADIUS. They are very keen to move to Office 365 and use SSO and my understanding is that they'll need to spin up a working ADFS implementation to arrange this. We want to use Microsoft tech to tie it all in, so 3rd party SSO apps I don't want to investigate.If a wireless client is authenticated with NPS, and we have a working ADFS implementation are they able to access Office 365 resources without signing in twice? I'd imagine that the NPS auth would give them the necessary DC token, but if they access O365 resources and get redirected to the ADFS website and use Windows integrated login, will it 'just work' ? They are looking at using the full...
This topic first appeared in the Spiceworks Community

did you find any resolution to this? our mba- mid 2013 deployment is having a very similar problem. We've gone through loads of troubleshooting and have yet to come to a resolution. all our mid 2012 mba's are working fine they're 10.7.5/10.8.4 mixed. console logs don't show much, i'll try the wireless diags tomorrow. our other 10.8.4 build appears fine on other models of machines. i've read posts about deleteing the adapters, deleting the system config plists and changing the mtu size, these steps do not work for us.
we don't have as high a failure rate with our deployment, but 25%-30% of our clients randomly drop connectivity and are unable to reconnect (fluttering wi-fi wave). when you slect the wifi symbol in the menu bar other wireless networks do not show, the 'looking for networks' fly wheel continues to spin. ocasionaly on login the yellow jelly bean will appear then disappear before finally timeing out without logging the user in (depsite having mobile accounts enabled). mostly the problem manifests itself when waking from sleep - the wifi symbol flutters endlessly without connecting. deleting the 8021x profile and readding it will reenable connectivity. we've tried new profiels, but to the same end. i know our certs and systems are fine because previous mac os x builds work fine as do our windows clients.
any input would be much appreciated.

802.1x supplicant authentication using a wired LAN.

We are in the process of creating a test enviroment to test 802.1x within our organisation.
We have a mixed Windows/OSX client enviroment and a W2k3 backend structure (Active Directory, Radius).
Phase one of the testing invloves wired only connections and authentications. The windows clients authenticate fine with the Radius server, which is connected to our test Active Directory.
The OSX clients (10.3.9, 10.4.3 and 10.4.11) have been bound to active directory and users can login ok if 802.1x is turned off.
When 802.1x is turned on the users can authenticate ok using the internet connection app to setup an 802.1x session.
However, it would be advantageous if we could also get the MAC to authenticate itself as a known system before any users log in (the Windows clients do this already).
Is this possible for OSX?
Is it because we are using Active Directory for the Macs?

Did you ever figure out a resolution to this? I'm facing the same problem. 802.1x authentication does not work for the system profile and I have to login and manually click the connect button for 802.1x.

802.1x port authentication failing after getting a access-accept packet

Hi all,
Im not 100% sure what the hell is going on here.
Any idea's or help will be appreciated.
Heres the topology.
1 x windows 2012 NPS
1x 3750X
1x Windows 7 x64

The switch that is doing the authentication is the 3750X. Here is the IOS version.
Switch Ports Model              SW Version            SW Image
*    1 54    WS-C3750X-48       15.2(1)E              C3750E-UNIVERSALK9-M
A wireshark trace on the NPS server shows that the packets are arriving and being sent back
Wireshark on a mirror of the trunk port connecting the 6513. It also shows packets being sent and arriving. access-accept packets are being recieved.
As you can see in the debug output, the switch is getting a access-accept, then it is stating a AAA failure.
here is a debug output as you plug in the laptop.
