ACS NAC and VLANs.

We are working on configuring a NAC Framework test network. We've got to the point where we can successfully evaluate and flag a client PC as healthy or quarantine and enable/disable it's switchport as appropriate. The next step that we are having a problem with is assigning the port to a VLAN, whatever we do the port always seems to stay in the default VLAN1. We've created additional VLANs for healthy and quarantined PCs but can't get the ports assigned whatever we try. We're pretty sure we are getting the syntax of the various settings in ACS correct as wherever possible we are using templates to create settings profiles and where no templates are available we've checked our settings very carefully.
The only error we can see is from a radius debug on the switch during the authentication process where it returns these messages:
03:48:39: dot1x-ev:Received VLAN is No Vlan
03:48:39: dot1x-ev:Received VLAN Id -1
There are several repeats of these during the debug.
Any ideas?

did you configure these 3 attributes? You must set them so that the VLAN ID/Name can be assigned correctly. And on the switch you must include AAA network too.
IETF 64 (Tunnel Type)Set this to VLAN
IETF 65 (Tunnel Medium Type) Set this to 802
IETF 81 (Tunnel Private Group ID)Set this to VLAN ID/name

ACS NAC and VPN

I am trying to set up NAC using ACS 4.1 and a VPN concentrator 3015 using 4.7.2K. I have had it working before using 3.3 and 4.0, but had to wipe out my server because of some issues. This is all in test, but I would like to complete this soon.
Is there some document out there that will allow me to see examples of this setup? I have googled it and checked on Cisco, but the examples are normally IOS specific. Any help would be appreciated.
Thanks
Dwane

Refer to the link to the NAC Phase One whitepaper which is the best guide to configuring NAC at the moment.
The document was released prior to NAC introduction on the VPN concentrator, but all the ACS and CTA configuration is valid.

802.1X for wired environments using Radius/ACS for Dynamic Vlan Assignment

Currently Being Moderated
802.1X for wired environments using Radius/ACS for Dynamic Vlan Assignment
Could someone please provide me with a simplest set of configuration steps to fire up Radius in ACS and 802.1X for dynamic vlan assignment. The objective is to roll out NAC L2 OOB using the 802.1X method for dymamic vlan assignments.
If possible show:
1. ACS/Radius Configurations.
2. End User Switch Configurations
Variables:
Switch A
MAC Address aaaa.bbbb.cccc     Vlan 10
            bbbb.cccc.dddd     Vlan 20
Also, if someone posts the Pros and Cons of using Radius/ACS/802.1X for Dynamic Vlan Assignments.
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.

NAC and AD, Machine GPOs, Roaming Profiles = Chaos

I've just observed a hapless Cisco consultant try to make NAC 4.1 work on computers with machine GPOs, roaming profiles, logon scripts within user GPOs, and for that matter legacy logon scripts with "run logon scripts synchronously" enabled. All of these technologies seem to fail on a NAC-enforced connection.
We assign software on machine GPOs and we use roaming user profiles, and it seems we either need to have a domain controller and profile share on the isolation VLAN, which defeats the purpose of NAC, or perform some kind of machine authentication, which can occur before GPO processing and net logons can happen.
While I'm not the Cisco consultant, it wasn't hard to recognize this problem.
Everything I've read about NAC and CAA suggests this is a per-user compliance solution and not a per-machine solution. Surely others have observed this, and I think this is what machine authentication (802.1x) NAC, as opposed to user authentication NAC, is all about. At the risk of sounding like a total n00b, where can I start researching a NAC solution that supports what I want and lets us use the Cisco NAC gear we've already invested in?

I have had similar issues and have solved many with a custom script that runs at log on. It is a compiled script and works great, AutoIT3.
The policy part takes care of itself if you leave machines logged in long enough or do a gpupdate /force. This will force the group policy to synchronize but you will need to log off and on again.
The roaming profile is much tougher. I am still trying to get this working. If anyone has any info on EXACTLY what takes place on a roaming profile synchronization, I would be grateful. If I can I will replicate that process in my script and solve this issue also.
I have fixed the log in script stuff with a delayscript that I use (ironically) clean access to install. You have to launch it with the users credentials, though and not from Clean Access which uses the SYSTEM users credentials in its stub agent!
This is a known issue to Cisco but any prodding of them to get it working would help. Their solution is braindead, just give unremediated machines full access! If they fail remediation, kick them off then. Gee, that gives the unremediated machine a mere two to three minutes to attack your AD DCs on each log in attempt. Not good.
Anyway, that's where I am at. Most of this can be dealt with, some is still problematical.

802.1x NAC and per-user ACLs

Can 802.1x NAC and per-user ACLs be used together on the same port? I know some of the NAC documentation says that 802.1x NAC does not support downloadable ACLs but it looks like it might be outdated and according to http://cisco.com/en/US/products/ps7077/products_configuration_guide_chapter09186a0080817284.html , it appears that there is not preventing this.
Also, when will URL redirection to a remediation server be supported with 802.1x NAC?

You just need to configure it differently on ACS. "Downloadable IP ACLs" used to be "Downloadable PIX ACLs" on ACS. It changed to "IP" when VPN concentrators started supporting this with ACLs too. You saw this with NAC, if I remember .. and EOU does it this way as well.
802.1X with per-user ACLs was already shipping at the time though (has been for some time) and the mechanism is opertionally the same .. just functionally different.
With per-user ACLs, you'd configure a VSA like:
ip:inacl#1=deny ip any host 10.1.8.3
ip:inacl#2=permit ip any any
The "downloadable IP ACL" config would look like:
deny ip any host 10.1.8.3
permit ip any any
In the end, both techniques use the same VSA. This VSA is 026\009\001. In "per-user-ACLs, there's no sort of handshake though to see if the ACL is already there, etc. It slaps the ACL on for you unconditionally as an authorization rule b/c you told it to. (hence the "ip:inacl" stuff above). With "downloadable", there's a handshake before actually applying the ACL .. to see if there's an earlier copy of the ACL, and it'll only update what changed, etc.
So, it really boils down to semantics. Both techniques work. AAA config is subtely different on the backend. Look for this to get consistently deployed soon, but in the meantime, it's still supported ;-).
Hope this helps,

Cisco NAC and Microsoft NAP

Dear all,
I need to know what are the differences between Cisco NAC and Microsoft NAP ?
Can NAP be used instead of NAC or not ? why ? why not ?

I really do not know if you will find the answer that you are looking for. From what I remember NAP was an option that was available with the ACS via a special patch. This is only supported for vista clients if memory serves me correct.
Here is the link that will help you with the basics.
http://www.cisco.com/en/US/netsol/ns466/index.html
We do not get much case volume or exposure to the NAP solution and with ACS 5.2 and ISE around the corner it might be too late to go through this setup and then run into issues with acs 4.2 possibly hitting eol/eos.
Thanks,
Tarik

How do I add a Subnet and vlan with a catalyst 3550 and RV120

Hello Friends.
I have a scenario that i'm hoping i can get some help with. I'll be as detailed and descriptive as i can.
This is for a business with 100 employees nodes and 100 camera nodes all needing IP internet through private addressing and public gateway.
I have a business class gateway with a private range of 12 public addresses. Ther modem does nothing but act as a gateway since i have disabled the firewall and DHCP.
In place of the firewall and DCHP from the modem i have installed a RV120 Firewall with VPN. When installing i replicated the IP scheme of the modem as to not disturb and distrup the devices assigned addresses from that scheme from the modem. I did this because the owner could not have any down time or any disruption to the business operations.
The RV120 now acts as firewall , DHCP , and VPN. I'll address the subnet first. I's using 10.0.0.0/24 subnet range.
DHCP is assigning 10.1.10.50 - 10.1.10.100 the rest are static and i plan to use static DHCP with the IP and MAC assigned to each static DHCP address.
There are 100 cameras with static IP addresses in the range of 10.1.10.11 - 10.1.10.40, and 10.1.0.1.101 - 10.1.10.170.
VPN uses PPTP assigned address 10.1.10.6 - 10.1.10.10.
There are no layer 3 switches that i know of. Just a layer two that is the primary swith and ports have run out, and various out of the box switches and wireless access points connected to the primary switch.
I want to implement subnets into the network and VLANS as well on a new Layer 3 switche from cisco. Thinking 3550 from Cisco or one of the older layer 2 switches with layer three capabilities.
I also want to introduce a 192.168.0.0/24 IP range for the existing wireless network and segment the traffic from the rest of the traffic on other ranges.
I want to replace the 10.0.0.0/24 DHCP alltogether and the static addresses for end user nodes on the same network, but keep that range just for camera nodes segmented.
I want to implement a NEW end user IP range and VLAN for employee/guest networks using the 172.16.0.0/24 range.
Iv'e thought of replacing all the wireless nodes with RV120's and use VLAN. Dont know if that strategy works. Need to think it through.
I want the 192.168.0.0/24 IP range comunicate to with the 172.16.0.0/24 and possibly the 10.0.0.0/24 range.
Any advice on how to do this?
As a side note the next step after this is to install a server domain controller as all the computers are all stand alones in their own workgroups. It's a simultaneous project that will introdue a DCHP, WINS, DNS server.

Hi Omid, it sounds like you're proposing the 3550 switch but you're not decided yet. The 3550 switch is a pretty old device and needs enhanced multilayer image. It may be more prudent to use a more current switch such as small business SG300 or SG500 as the feature set is more rich and it supports around 480 LAN connections.
To answer the inquiry, the RV120W, when you create a VLAN it will automatically create an IP interface. From this you may assign subnet as you like along with 'enable or disable' for inter vlan routing. Since the RV120W has this feature, a layer 3 switch is not required unless you are looking to keep the routing load smaller by routing locally with the switch.
With Catalyst or a small business switch you would need to create a VLAN. After creating the VLAN, on a Catalyst you can simply issue "switchport trunk encapsulation dot1q" on the desired interface and all VLAN will passage without issue. For a port connecting a user "switchport mode access" "native vlan xx" This will assign the port as untag member of the desired VLAN.
If using a small business switch, it is slightly different, you still create the VLAN but the command issue is a bit different "switchport trunk allowed vlan add xx" for the link to the router, where xx = the VLAN ID to tag to the router. For access client it remains the same as Catalyst.

Logical network to physical network mapping (subnets and VLANS) in SCVMM 2012 R2

In much of the blogs, documentation and literature on VMM, there are examples of deploying multiple logical networks onto one physical network i.e. Cluster (logical) + Storage (logical) + Backup (logical) + Live Migration (logical) + Management
(logical) on top of Datacenter (physical).
Does this mean it would be possible to have one (physical) flat VLAN-less network with one subnet and then have all those logical networks (with subnets and VLANs) on top of it? Even with a simple unmanaged L2 switch that doesn't support VLANs itself?
If not, just how do you map multiple logical networks to just one physical network? How does that work in practice? Is a L3 switch needed to route traffic between logical networks for example?

Hi. VMM Networking may be overwhelmed for the most, at first. But you really need to understand the modeling here and how things are related to each other. Especially if using NIC teaming in WS 2012 (and R2) together with this mix.
I suggest that you read the following whitepaper where we explain how to setup networking in VMM (also to support network virtualization, but that is absolutely not mandatory): http://gallery.technet.microsoft.com/Hybrid-Cloud-with-NVGRE-aa6e1e9a

What is the exact purpose of Transaction NACE and NAST Table?

Hi All,
What is the exact purpose of Transaction NACE and NAST Table?
Pls help me
Akshitha.

Hi
When a Output type in an apllication doc is configured with a Medium, Partner, Lang and other communication paramters an entry is created in NAST table
so to trigger the output an entry in NAST is compulsory
Output is a link between the Driver Program and the Sapscript,
An output type summarizes messages of the same meaning. It contains parameters that are valid for all its assigned messages, for example appropriate partner functions.
Transmission medium is a medium which the layout will be come out, this may be printout, Fax or Mail
Check this link.
http://help.sap.com/saphelp_nw2004s/helpdata/en/c8/19884743b111d1896f0000e8322d00/content.htm
ex-how to config output type.
You will assign output types using Transaction NACE.
Do the follow steps to assign output type
1)Select Application Type V2 which will have description Shipping.
2)Click on Output types button.
3)Go to change mode by pressing Ctrl+F4.
4)Select one output type which already exists
5)Do Copy As(F6)
6)Give your output type against Output Type field.
7)Under General data Tab, Give Program and Form routine and Save the data.
i think it a work of functional guy but at senior level i think it is not a big deal for abaper.
Check the following documentation
In NACE t-codewe have the application for each one. based on the application output type can be defined, based on output type script and print progrma can be defined.
If suppose data can be read from EDI then we should go for condition records.
So whenever we execute the script first composer checks the output type and then execute the program. in program whenever opn form FM will be populate then script will open first. After that again program till another FM will populate if it then script will populate........like it is cycle proces. Composer does all these things and at last it will submit that output to spool.
Go to the Transaction NACE.
choose the related sub module.. like billing or shipping
doubel click on Output Types
Choose the Output Type for which whcih you wanted your script to trigger
Then select the Output Type and double click on Processing Routine
Then go to create new entries--> Select the Medium (1- print output), then enter your Script and Print Program detls --> Save and come out
Now go to the Transaction (for which you have created the output type)... Issue output--> Select the output type --> Print....
Device Types for SAP Output Devices (Detail Information)
Definition
The device type indicates the type of printer to be addressed. When you define an output device, choose the name of the device type that was defined in the SAP System for your printer model, such as Post2 for a PostScript printer. In the case of frontend printing under Microsoft Windows, you can also use the generic (device-independent) device type SWIN.
The system uses the information in the device type to convert a document from the internal SAP character representation (spool request in OTF or in text format) to a device-specific, print-ready data stream (output request). Since a device type specifies attributes that apply to all devices of a certain model, it can be shared among device definitions. For example, all devices in the SAP spool system that are compatible with Hewlett-Packard LaserJet IIID printers would use the HPLJIIID device type.
You should not confuse the device type with the printer driver. The device type is the total of all attributes of an output device that the SAP System must know to control the output device correctly, such as control commands for font selection, page size, character set selection, and so on. These attributes also include the printer driver that SAPscript/Smart Forms (the SAP form processor) should use for this printer. The SAPscript printer driver that is to be used for devices of this type for output formatting is therefore only an attribute that the device type specifies.
How do I choose the correct device type?
In most cases, the SAP System already provides the appropriate device type for the printer type for the printer model that you want to use.
These standard device types are completely defined and need no modification or extension before you use them in device definitions.
You can also download missing device types from the sapserv server. For a current list of the supported device types, see SAP Note 8928 in the SAP Service Marketplace.
Most printers can be controlled using a generic format, such as PostScript. They can be switched to a mode that is compatible with one of the standard printers for which an SAP device type is available. In this case, a supported model is emulated.
Almost all printers are delivered with Microsoft Windows printer drivers. The system can control these printers with the generic (device-independent) device type SWIN. The Microsoft Windows spool system then performs the processing of the print data.
If the specified device types are not available, and generic device types cannot be used, you must create your own device type or edit a copy of an existing device type. We recommend that only those with specialist knowledge of the SAP Spool System and printer driver code do this. For more information, see Defining a New Device Type .
Attributes of a Device Type
A device type is distinguished by the attributes listed below. If you change an existing device type or create a new device type, you must change at least some of these attributes.
Character set: A character set specifies the codes with which characters must be represented in the print-ready output stream (output request). This code replaces the generic SAP characters set that is used internally by the SAP spool system (spool request).
Printer driver: You can specify different printer drivers for printing SAPscript documents and ABAP lists.
Print controls: Print controls represent printer operations, such as boldface or changing the font size. These print control are replaced by printer-specific commands during the creation of the output request from a spool request.
Formats: Formats specify the format supported by the SAP system. The system differentiates between SAPScript formats (DINA4 and LETTER) and ABAP list formats (X_65_132 = 65 rows/132 columns).
Page format: A page format is the interface between a format and SAPscript. It specifies the paper dimensions with which SAPScript can calculate the row and column lengths.
Actions: Actions are output device-specific commands that are required for the implementation of a format. The action printer initialization, for example, can contain a printer command with which the number of rows on a page is defined. There is a set of actions for every format supported by a device type.

WLC2112 with Guest / Web-Auth and vlan

Hi
I'm trying to configure my WLC with guest SSID and vlan 10.
The security is only set to Web-auth, and it is all working if the guest network is set to nativ vlan (1) But it seems that the http(s)://1.1.1.1/login.html is not reacheble from the guest SSID/VLAN??
Please help.
Management IP Address 192.168.14.252
Software Version 6.0.182.0
Emergency Image Version
I have tried with ver. 5.2 also -

I think that 1.1.1.1 is only reachable from a wireless client during webauth. They should not be able to reach that address once they have passed through the web auth page.
Don't know if that helps, or not.

NAC and Checkpoint firewall

Hi to all,
Does anyone know if it is possible to configure SSO using NAC and a checkpoint firewall VPN client software on an user machine??
Thanks in advance for your help

Mark,
If the checkpoint device can do standard radius accounting, it can work with CCA. When doing VPN SSO with CCA, it only cares about the accounting packets from the VPN head-end.

NAC and WSUS

Hi to all,
I'm new at NAC, does anyone know the steps on how to configure the remediation on a client machine using NAC and WSUS?? Is there a rule that match it??, etc, etc...
Thanks in advance for your help!

Click clean access under device mgmt.
Click the clean access agent tab.
Click requirements.
Add one for MS update check if you don't already have one made by clicking new requirement. Choose windows update service for the requirement type drop down box. If you already have a rule for the windows update service check you can click edit instead (next to the move up down arrow buttons).
About half way down you can choose MS servers or WSUS servers.

Help with wireless controller and VLANs

Hi I'm trying to setup a wireless controller in preparation for a large site go live later this year. I'm struggling to get the controller and the WLAN using the correct VLAN. I want the controller on VLAN 100 and the clients on the WLAN on VLAN 200.
My thought is that I would need a config similar to:
Switchport for wireless controller management port set to trunk VLAN 100 and 200 with no native VLAN set.
The management interface on the controller set to VLAN 100.
A dynamic interface created on VLAN 200.
When setup like this I can get to the controller on its management address but only from VLAN100 not from another VLAN on site or from other sites over the WAN.
I have setup a WLAN which is set to use the dynamic interface on VLAN 200.
I have set the AP to use HREAP and set the native VLAN as 200 and added the dynamic interface into the VLAN mappings
When I connecting a client to the WLAN I get an address on VLAN 100.
The switchport for the AP is set to native VLAN 100 and trunk 200 – this setup works for standalone APs at other sites.
What am I missing?
Also any idea why the management interface address is not routing? The netmask and gateway are set correctly.
Thanks
Paul

Just to add to Steve's post... You only need to create a dynamic interface for vlan 200 if you have ap's also in local mode. If your ap's are in H-REAP/FlexConnect mode, you don't need a dynamic interface for vlan 200.
In you H-REAP/FlexConnect ap, you would set the wlan to vlan mapping there and the switchport configuration would be a trunk allowing vlan 100 (im assuming your native vlan for your ap) and vlan 200. You should see something like the following:

IPMP and VLANs
