ACS + VMWare thin clients with dynamic vlans

Good afternoon,
I need to deploy a solution with thin clients and dynamic vlans (802.1x). All switches are catalyst 3560 and superior
Can I do this using only de ACS? Will it work?
Thank you

Hi,
Dynamic Vlan assignment can be configure on the ACS.
Please see the configuration example on the link below, this configuration example is for WLC but the ACS configuration is the same.

802.1x authetication with dynamic Vlan assignment by a radius server

Hi
At school I want to start using 802.1x authentication with dynamic Vlan assignment by a Windows Server 2012R2 Radius server.
When a student logs in, I want it to be placed in the "Students" Vlan, when a Administrative employee logs in, I want it to be placed in the "Administative" vlan and when the client is unknown I want to place it in the "Guest" Vlan.
I have several SG200 switches and I configured everything as mentioned in the administrative guide but I cannot get it to work as desired.
What does work:
- If the client is permitted, the switch changes to "authorized" state. (before anyone logs on to the domain with that client)
- When a User logs on that is part of the Administrative employees, the switch changes to "authorized" and when a student logs on, it changes to "unauthorized".
So far so good.
But what doesn't work:
- it does not put the administrative employee in the Vlan "Administrative", it just enables the port on the switch but leaves it in the default vlan 1.
- I can not find the Guest VLAN.
Any help would be appriciated.

Hi Wouter,
Can you see in the packet capture Radius accept message VLAN attribute? Also please ensure you have the latest firmware and boot code:

ACS with Dynamic VLAN which protocol to use ??

Hello,
Which Protocol do I need to use, for providing dynamic VLAN to my desktop machines?
As in ACS 4.0 if I use local database of ACS then users successfully get the dynamic VLAN & as soon I use AD database while integration it with ACS ,the authentication fails!!
Please help.

Hi,
Thanks for the reply. I am using EAP-MD5.
However, the problem is if I am using ACS solution Engine local database, users are getting dynamic VLAN after authentication.
But when I use AD as user database, the authentication fails. Even strange thing is that if I use AD database to log in to any Cisco Router then the authentication is working fine.
Even I am struggling with TAC also from last week in two different cases! However, they are unable to help! I found TAC has limited resource for ACS.
So please suggest what to do as on Cisco site, I found lots of stuff for Wireless but I have only the desktops (no wireless).
So will the mention below URL be of any help?

Q Thin Client with WES 7/8 virtual licensing

Dear Support,
Could you help us, do we need a VDA or SA if we will use
Thin Client PC with Windows Embedded Standard 7/8?
Thank you.

Thanks man for the information.
Answers from microsoft are not really direct from the point.
VDA, Software Assurance and Windows Embedded Thin Clients
If you use Microsoft Software Assurance and you have a Windows Embedded Thin Client (Windows Embedded 7/Windows Embedded 8), then you can now move this into your SA, thus negating the need for VDA licensing. This means the total acquisition cost is potentially
lower than equivalent PC’s and even Linux based Thin Clients or Zero Clients due to the Annual Charge of VDA.

Dynamic Vlan Assigment on 2950 with acs 4.2

Hello to everyone
We have a problem with Cisco 2950G 48 EI and ACS (version 4.2) providing dynamic Vlan assignment based on groups
On the ACS we configured the following attributes for the specific group
64 = VLAN
65 = 802
81 = VLAN Name
We tried for the 81 attribute both Vlan name and Vlan ID but we get the same results
In detail, we need the machine to be placed on Vlan ID 6 named vlan_sio so we inserted these value in the attribute field
Before we configured the switch to speak with ACS:
aaa new-model
aaa group server radius Switch
                               server 172.16.0.93 auth-port 1812 acct-port 1813

                radius-server host 172.16.0.93 auth-port 1812 acct-port 1813 key xxxxxx
radius-server retransmit 3
Configured the ports for the use of dot1.x.
switchport mode access
               dot1x port-control auto
               dot1x guest-vlan 7
               spanning-tree portfast
The users are correctly authenticated but the ports are always connected to the default Vlan of the ports
We tried to debug with the debug dot1.x events command and we get the following errors:

Does anyone know what we could have missed?

Other technology sets that can be used for Dynamic Vlan assignment EXCEPT from deprecated/obsolete VMPS.
Thanks in advance. .

Hi Guys,
    Hmmm, well if your just looking for Mac based authentication the good news is that is very easy. Just set create your Radius server, ACS, FreeRadius, Steelbelted radius etc. Then create user with the name of the Mac address, in other words if the mac address is 0012.0021.1122 the the name would be 001200211122 and the password would be the mac address. Then you set the vlan and tunnel stuff, like so tunnel-Type would be vlan, Tunnel-medium would be 802 and Tunnel-Private-Group-ID is the name of the vlan(not the vlan number)
   So for the Cisco ACS 4.x you would create a user as specified above, fill in all the password boxes with MAC address, I believe the mac has to be all lower case in the name and the password. Then check the Separate(Chap/MS-Chap/ARAP) box. Then you pick the group the machine belongs to, the group is the part that defines what vlan it is on.
   Before you create the user, create the group with info I wrote above and in addition specify the Service-Type as Authenticate Only.
    Freeradius is a bit harder to configure the specifics and I am just now testing a freeradius server so I do not know the process for Machine authentication.
    If, however, you are trying to authenticate a user that gets a bit trickier and is not so straight forward.

802.1x dynamic vlan assignment using ACS 4.2

Hi
we have 10 switches 2960 configured with 802.1x authentication against ACS server 4.2.
we have 2 vlans configured on the switches for administrator and endusers. the end user vlan id is 10 and the administartor vlan is is 100.
we need to apply the following scenario, if the enduser PC - that is connected to vlan 10 - has an issue and the administrator will login to the PC with the administrator account to fix that issue, the switch should dynamically reconfigure the port with the administrator vlan ( 100 ) .
is the above scenario doable using dot1x with the ACS server?
waiting your replies

Hi,
I have the following scenario
2 bulidings with multiple floor
Each floor should be in different VLAN.
The network should be authenticated with 802.1x and each switch port should be assigned with dynamic VLAN from ACS.
Each
user should be able to connect and roam around between any building.
when ever a user is connecting his laptop to any floor, he should be
made part of that respective vlan. It is not requred to have the same
IP rage to be allocated, but the dynamic VLAN should be based on the
switch port location.
Can
I configure ACS in such a way that, the ACS will allocate dynamic VLAN
for every 802.1x authentication based on the Network Device Group.
Please refer the attached diagram

802.1x RADIUS with EAP-TLS/EAP-TTLS & Dynamic VLAN Assignment

Hello, My team is looking for switches supporting 802.1x authentication on either EAP-TTLS or EAP-TLS protocols with dynamic vlan assignment enabled for these. Looking at the data sheets of the Linksys desktop switches, I found only SLM224G4PS and SLM224G4S models to support EAP-TLS or EAP-TTLS. Am I right? Do they support Dynamic VLAN Assigment for either of those protocols? This is not explicitly mentioned in the data sheets, and I happen to find switches from other manufacturers that announce to support EAP-TLS/EAP-TTLS but no dynamic vlan assignment. Thank you for any help.

SLM switches do support 802.1x RADIUS with EAP-TLS/EAP-TTLS unlike the SRW switches which support MD5. But I don't think that they support Dynamic VLAN.

I've got a problem with dynamic vlans. Trying to figure out configuration for the topology similar to the one in the picture.
I’ve got four vlans for PCs, one vlan per department. I have to add fifth vlan (50) for devices that can be connected to any of the three switches: A, B, C. these devices need to be on their own vlan, no matter to which switch they are connected to. On the other hand, PCs connected to any port on those switches should be assigned to appropriate vlan (10,20,30 or 40).
I was thinking about using dynamic vlans with list of mac addresses of devices that need to be on vlan 50 but not sure what to do with PCs. I don’t think I can use fallback vlan as I can set up only one fallback vlan for whole network and not per switch or port.
I cannot use list of mac addresses of all pcs as there’s simply too many of them (my network is way bigger than in the picture, I simplified it only to present the idea). I imagine I would need multiple fallback vlans for different switches.
Has anyone got any idea that could help me please? Maybe there’s some other and easier way?

In new software (for Cisco switches) we provide multiple fallbacks for MAC authentication (MAB):
1. 802.1x
2. web authentication
3. guest vlan (if no supplicant on the PC)
4. auth fail vlan (if radius denies you access)
So you could keep a list of MAC addresses for vlan 50 and do MAB for these devices if MAB fails you can use 802.1x for your PCs.
This will require configuring 802.1x supplicants on all PC (Windows comes preloaded with one) and maintaining a radius of users who are able to log into the network. A lot of people use their Active directory pre-existing database as a backend to store their usernames and passwords for user authentication with dot1x.
With using both dot1x and MAB you can now distinguish easily between two different processes and use your radius server to assign vlans based upon almost anything you can think of.

Dynamic VLAN/SSID assignment w/IPv6

I have followed the answer in this discussion which instructs on how to get Dynamic VLAN/SSID assignments using WLCs + MS IAS:
https://supportforums.cisco.com/thread/339396
This works great for IPv4. This does not appear to work for IPv6.
I have CT2504 WLCs running v7.0.116.0 and AP 3502s. I have a Windows 2003 IAS working for 802.1x authentication using PEAP and per-user/group dynamic VLAN/SSID assignments. Based on who you authenticate as, you are placed on the appropriate VLAN.
However, IPv6 does not function properly. I believe this is due to the nature that the WLC only bridges IPv6 from the Interface Group that the WLAN is assigned to and/or whatever Multicast VLAN you assign.
If I connect as a user assigned to the same matching VLAN as the WLAN Interface / Multicast VLAN, IPv6 works just fine. I do not even have to have the "Enable IPv6" box checked in the Advanced tab, nor does the "Multicast Vlan Feature" need to be enabled - IPv6 still works.
If I connect as a user that is assigned to a different VLAN than the WLAN Interface / Multicast VLAN, I see the IPv6 Router Advertisement from the WLAN Interface / Multicast VLAN, and not the VLAN that "Allow AAA Override" switched me to. Naturally since I'm getting as IPv6 prefix for a different VLAN, when I try to route traffic through the IPv6 default gateway (which isn't on the VLAN I'm connected to), it doesn't work.
One work-around to have IPv6 support is to use distinct, non-dynamic per VLAN/SSID assignments. This is ugly and doesn't scale (16 max SSIDs).
Has anyone else experienced this and know of a solution?
For now I'll just have to set the WLAN Interface to a VLAN which does not have IPv6 enabled and my wireless users won't have IPv6 unless they VPN on top of Wifi. Rather disappointing.

this sounds alot like another implication of IPv6 with "more than one VLAN on the same SSID".
see this thread:
https://supportforums.cisco.com/thread/2157621?tstart=60
not with dynamic vlan, but vlan select - which, on the L2/L3 on SSID-side is essentially the same.
as mentioned in the thread, 7.2 has a feature that "automatically sends the correct RA to the correct clients via L2 wireless unicast. By unicasting the RA, clients on the same WLAN, but a different VLAN, do not receive the incorrect RA."
lucky for you, 7.2 is available for the 2504 - with my WiSM1s I am out of luck :-(
so this feature *could* solve this problem, as the problem is that the wrong IPv6-RAs are broadcasted for the client (because the SSID is the same)

Flexconnect dynamic VLAN assignment doubt

Hi, all,
I am trying to understand how FlexConnect with dynamic VLAN assignment works. We have the need to dynamically put people in different VLANs based on their AD groups (all employees use the same SSID), I can understand that in traditional CAPWAP mode, AP just tunnels all traffic to WLC, WLC is the authenticator and it knows what users' identities are and can encapsulate user traffic to different VLANs before send the traffic to the switch it connects. Here is the part I don't understand:
1) If APs are operating in Flexconnect mode (APs are trunking to switches), how does each AP know what VLAN tag to put a specific user traffic on? AP is not authenticator, it knows nothing about associated client's AD identify. How does WLC convey the dynamical VLAN information to APs?
2) I want to eliminate WLCs in remote offices by letting all remote office APs join HQ WLC with FlexConnect mode, I can keep the same VLAN mapping scheme in remote office switching environment, in some offices I want to do local authentication (Domain controller + Radius Server), looks like I can specify Radius server in FlexConnect group, in this case will APs become authenticator? Since Radius clients have to be explicitly configured on NPS/Radius server side, does this means I have to statically configure each AP's IP?
3) I have over a dozen APs in HQ which are operating at FlexConnect mode, but the SSID's "local central authentication" checkbox is not checked, if I want to have local authentication in remote office, seems that I have to turn on "local authentication" on this SSID, does that mean I have to add each and everyone of those HQ APs to Radius/NPS server client list?
Thanks,

Hi ,
1) Aps knows about Vlans as we can define them inside the Flex connect groups. This is the same way we define flex connect ACLs which are pushed to the Flex APs and are returned by the Radius server later on.
2) If you are going for Central authentication + local switching ....WLCs will always act like central authenticator and would talk to the radius server. If you have some radius servers at the local site and you want them to use without going through the central authentication..you can do that using (local authentication + local switching). Yes, In this case AP will be authenticator and would be AAA client to be added in the Radius server.
3)yes ,,you are correct. If you want that your AP should do authentication and talk to the local radius server at the site , it has to be added in the Radius server.

5508 and dynamic vlan assignement

Hello,
I'm trying to setup a 5508 to work with dynamic vlan assignement using the same SSID.
I've followed everyting in this document http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a008076317c.shtml
but it doesn't work, every client independent of the RADIUS group is assigned to the same VLAN.
The only difference I have with that document is the [081] Tunnel-Private-Group-ID for which I use a string (nessesary for the LAN switches which use the same RADIUS) instead of a number.
What I see when sniffing the RADIUS traffic, every option is sent correctly to the WLC, from the WLC side and using the debug aaa events enable option I see nothing interesting.
Any ideas?
Thanks
George

A bit more debugging gave me this:
*Oct 15 09:31:28.491: xx:xx:xx:xx:xx:xx Received Tunnel-Group-ID Attribute -- ignoring AES Interface-Name '200' for STA xx:xx:xx:xx:xx:xx.
*Oct 15 09:31:28.491: xx:xx:xx:xx:xx:xx Tunnel-Type 16777229 should be 13 for STA xx:xx:xx:xx:xx:xx
(xx:xx:xx:xx:xx:xx is the client mac address)
It seems that:
1. WLC ignores the [14179\005] Aire-Interface-Name parameter regardless of what the value is (I have tried the vlan number, the interface name etc)
2. the second error is that the tunnel-type 16777229 should be 13. The tunnel-type has the value VLAN as required according to the Cisco document and in general for this to work. Funny thing is that RFC2868 doesn't define a value of 13 but RFC3580 define VLAN as value 13 so again I've set the correct value.
So I don't really know what to do now. I guess I have to open a TAC ticket.

SG200-26: dynamic VLAN - 802.1X

Last week I got my SG200-26 (SLM2024T-EU). The Data Sheet says, that the switch works with dynamic VLAN assignment over 802.1X.
IEEE 802.1X
(Authenticator role)
802.1X: RADIUS authentication and accounting, MD5 hash
Supports time-based 802.1X
Dynamic VLAN assignment
The authentication on freeRADIUS works. I client could get access to the network after entering username and password but the client is not assigned to a VLAN. I used wireshark to sniff the authorisation process between the switch and the freeRADIUS server and the VLAN information were transmitted to the switch.
I would appreciate if some could give me some help how to configure the switch to work with dynamic VLAN assignment and freeRADIUS. If you need some more information, please let me know. I will add them here as far as possible.
Thank you very much!
Alexander
Edit

Hello Nico,
Thank you for your reply.
I will show you my scenario a little more in detail and explain, what I have configured:
I have got one server/router with a VLAN capable NIC connected to Port g1 on the switch. On the router I created 2 VLANs with VLAN-ID 5 and VLAN-ID 6.
Both VLAN "NICs" have a static IP address and there is running a DHCP server for each VLAN. On the same server there is runninga freeRADIUS server.
Now I did the following configuration on the switch:
1. I assigned a static IP on the switch.
2. SECURITY -> RADIUS:
I added the RADIUS Server IP address and the key string (same on switch and freeRADIUS) and I ticked Usage-Type: 802.1X
3. SECURITY -> 802.1X -> Properties
Port-Based Authentication: Enabled is ticked
RADIUS
4. SECURITY -> 802.1X -> Port Authentication
Administrative Port Control: Auto is ticked
5. VLAN-Management --> Create VLAN
VLAN-ID 5
Descr. VLAN5
VLAN-ID 6
Descr. VLAN6
I think, to this point the configuration is correct, isn't it ?
I would appreciate very much, if you could give me advice for the further steps like Port Mode Access, Trunk or General for the clients which connect to the switch and if tagged or untagged.
I have port g1 in trunk mode and VLAN5 and VLAN6 is tagged because my NIC is VLAN capable. But the other clients which connect to the switch do not have a VLAN capable NIC and these clients should get their VLAN assigned dynamically.
I attached the pcap file which contains the authentication between freeRADIUS and the SG200-26 (Port g1)
Thank you very much in advance!
