Ise radius/nac

Can ISE 1.1 act as a RADIUS for WGB through WLC?
thank you

Tarik,
Thanks for your answer, here is the problem !!!
In order to do PROFILING/POSTURING and all that for wireless clients here is what's needed:
Need to go to WLC (wireless controller) and choose RADIUS/NAC for the SSID.
So SSID = test RADIUS/NAC - then all normal clients go through ISE and get postured and profiled and all that works fine except...
WGBs cannot connect to SSID=test at all and they do not appear on ISE as an attempt at all.
As soon as I remove option RADIUS/NAC from WLC wgb connects and shows up on ISE fine and get authenticated ---> you would say well there you go that's ur problem , well yeah but if i DISABLE Radius/Nac option from WLC I lose the ability to control normal users that connect to SSID=test so it would just be PERMIT/DENY ACCESS based on username and the whole point of ISE would be ACS or Simple Radius Server.
Do you get my point?
Thank you.
P.s so for me to POSTURE/PROFILE wireless clients I need to use RADIUS/NAC option and for WGBs I have to setup a NEW SSID and leave that SSID without RADIUS/NAC option so it can only authenticate through ISE and not posture/profile clients, and I do not need to posture/profile clients behind WGB (it would be great but I don't necessarily need to, and I know they don't support CoA Change of Access attribute in RADIUS)

FlexConnect & ISE ACLs - AAA Overide/RADIUS NAC

Hi Chaps,
I have 3 ACLs configured on a WLC for CWA, Corp and Guest users. On local mode APs, theses are called up using the Airespace fields in the ISE policies dependant on what rule is hit.
ACL-WEBAUTH-REDIRECT
ACL-PERMIT-CORP-TRAFFIC
ACL-PERMIT-GUEST-TRAFFIC
Will FlexConnect APs call up the ACLs in the same way as a local mode as the WLAN will be AAA Override/RADIUS NAC or will FC ACLs be required.
Cheers,
N

I believe you need to create Flex ACLs on the fWLC. These Flex ACLs can be called the same as regular ACLs so in ISE you wouldnt have to change the auth profile.

Radius NAC VLAN select support

Hi all,
I have digged through the WLC documentation for 7.3 and in the chapter about Radius NAC I read that the VLAN select feature is not supported.
Does anyone know if this will change?
VLAN select is actually a useful feature and I wouldn't understand if NAC support over the ISE won't be possible.
Hope someone can shed some light on this.
Regards,
Patrick

I think with radius the vlan select and dynamic vlan assignment are two different topics. You can have ISE set users on different vlans within the same WLAN as long as the interface is present on the controller. I have tested this and works just fine.
The vlan select maybe a topic that the wireless folks can shed some light on.
Thanks

ISE Radius - Access-accept is returned with no autorization policy

Hello,
With ISE Radius service / PAP, the authentication passes OK, but the Network Element which send the autorization request, returns message "not enough user priviledges to execute command" and the HTTP page is blank.
The reason for that is, the Network Element is sending in the Access-Request with Service-Type value = 8, which means Authenticate-Only (and this can be seen at ISE . This causes the Radius server to authenticate, but not to send the authorization parameters back to the NE in the Access-Accept, causing the login to fail. A bit inside of the RFC:
5.6. Service-Type
    Description
       This Attribute indicates the type of service the user has
      requested, or the type of service to be provided. It MAY be used
      in both Access-Request and Access-Accept packets. A NAS is not
      required to implement all of these service types, and MUST treat
      unknown or unsupported Service-Types as though an Access-Reject
      had been received instead.
   Type
       6 for Service-Type.
      The Value field is four octets.
       1      Login
       2      Framed
       3      Callback Login
       4      Callback Framed
       5      Outbound
       6      Administrative
       7      NAS Prompt
       8      Authenticate Only
       9      Callback NAS Prompt
      10      Call Check
      11      Callback Administrative
There is no way to modify the value on the network element in the Access-Request packet.
Question: Is there a way to for the Cisco ISE to ignore the service type value (Authenticate Only), and return the autorization parametes back with the Access-Accept packet?
Thanks,
Lucho

Lucho,
I Checked the rfc and the answer is no, rfc states that no authorzation information needs to returned for this request.

ISE and NAC wireless guest networks

I have a wireless network that is NAC controlled and use lobby ambassador for guest wireless. What is the best way to migrate to ISE for guest. Are there problems running NAC and ISE on the same controller?
Sent from Cisco Technical Support iPad App

Hello,
For your query regarding ISE and NAC following are my findings, which might help you in order to solve your query.
for your first question:-
ISE is a free software upgrade for customers who have NAC appliance or NAC profiler. This is for both for the base and advance licenses.
ISE is a 50% software discount for customers who have NAC guest server. The 50% discount is a migration part for the base license only. The advance features license will not be impacted by this discount.
for your second question:-
There should be no issues running NAC and ISE on the same controller until and unless you are using two SSIDs.

Cisco ISE or NAC Guest with web security (IronPort) integration

All,
We have a scenario where guests will be authenticated against the ISE or NAC Guest server, and customer will place an IronPort to provide web security, however, we can not find referentes whether IronPort can or cannot integrate with Guest Server, so that guests are not requested to be authenticated twice, one by the Guest Server, a one by the proxy. The idea is to keep it transparent for the guests with a single authentication.
Has anyone there implemented such scenario?
Thank you!

I see. So, lets say we disable proxy authentication for the guest segment, can I still provide content filter for the segment, even though there is no proxy authentication? I assume customer will lose the reportinga and tracking granularity, but the scenario will work withou proxy authentication. This may be some sort of "man in the middle" only, but with content filter. Does it make sense?
Thank you!

Difference between ISE and NAC?

Well ISE is the next generation of NAC and has extended the features some of the comparison of features are mentioned in the given diagram

Radius Nac

Hi,
I try to mount a NAC lab with the following architecture :
- 802.1x on switch ports
- ACSv5 with an external database (windows) for machine and user authentification
- ACS v5 do vlan assignement and it works great.
- Nac Manager
- Nac agent on workstations : tried with CTA or CAA
I try to add a posture validation to check for the presence of an antivirus.
So I insalled a NAC Manager and add a "External Policy Check" on my ACS policy rule.
The Endpoint has CTA or CCA for posture validation.
It seems ACS doen't even try to make the request to the manager. I get the following error in ACS :
STEP_79=15038 Skipping External Policy because of missing or malformed required attributes
My question is : What do I need to do external posture validation with acs5 to a Nac Manager.
The guide reference I used is : http://www.cisco.com/en/US/docs/net_mgmt/cisco_secure_access_control_system/5.0/user/guide/common_scenarios.html#wp1053461
Thanks for your answer

ISE and NAC Agent

Hello, we currently run NAC for our wired (OOB), wireless (IB) and VPN (IB) enviroments. We are looking at migrating over to ISE for our wireless enviroment as a first step, with follow-up projects to move the VPN and wired clients over. I have been reading that ISE will still use the NAC agent. Our current NAC enviroment is at 4.7.2 and we are running the 4.7.2.10 agent. We do not want to upgrade this enviroment, we would rather focus on migrating to ISE. So our thought was to upgrade the clients to the latest NAC agent version 4.9.1.5. This agent is supported against the 4.7.2 NAC Manager. The problem is, I do not see this agent version listed as supported in the ISE compatibility matrix. Instead, they list a NAC agent of 4.9.0.37, which ironically, is NOT listed in the NAC compatiblity matrix. So what version of NAC agent should we run in a mixed enviroment? I am hoping 4.9.1.5 is supported against ISE, and the matrix is simply not updated yet. Thank you in advance for your help.

Not sure I understand. The 4.9.1.5 NAC agent does run against our CAM, as we have tested that and it is listed in the support matrix. So if we upgrade our NAC applainces, we would still run that agent. Does that agent tun against ISE, and if not, what is Cisco's recommendation to bring ISE into the enviroment? We have to have a migration path, and wireless seemed like a logical first step. But we need a NAC agent that will work against Clean Access AND ISE as our laptops will be wireless and wired at different times. Which Agent would be recommended?

ISe with NAC agent pop up and Posture waiting

Hi,
I have ISE running ver 1.1.1.268. We limited access certain services before authuenticate with ACL-DEFAULT(given below) as per the Trustsec desgin guide.
Now the issue is that when you have ACL-DEFAULT on the port NAC agent doest not pop-up and doest not start the posture part and saying waiting for Posture validation. When the ACL-DEFAULT removed from the access port NAC agent popup and do the posture validation.
However we do not want user to get access to network before the authorization and that is the reason we use the ACL-DEFAULT.
Please can someone advise me how to achieve the above both task. Why the NAC agent does not popup and do the posture when ACL-DEFAULT there in the switch.
Here is what I have configured on ACL-DEFAULT.
ip access-list extended ACL-DEFAULT
remark DHCP
permit udp any eq bootpc any eq bootps
remark DNS
permit udp any any eq domain
permit tcp any any eq domain
permit udp any any eq 389
permit tcp any any eq 135
permit tcp any any eq 445
permit udp any any eq 445
permit tcp any any range 135 139
permit tcp any any eq 389
permit tcp any any eq 3268
permit icmp any any
remark PXE / TFTP
permit udp any any eq tftp
permit tcp any host 172.xx.xx.xx eq 8443 (ISE-Pri)
permit tcp any host 172.xx.xx.xx eq 8443 (ISE-Sec)
remark Drop all the rest
deny ip any any log
Appreciate if someone can give a solid resolution and explanation to this.

Hi Saurav,
We have already allowed those ports with another acl (ACL-POSTURE-REDIRECT). Our issue is not with the web nac agent.
The issue is with NAC agent installed on corperate PCs connecting via wired port. With the ACL-DEFAULT it does not pop-up and does not do the posturing, however once we removed the ACL-DEFAULT from the access port, everything works fine.
Since we do not want any user to access unwanted services before authorization we add this ACL on the access-port and as per the trustsec desgin this has to be there if you want to have ISE with closed mode.
thanks

Cisco ISE - radius proxy

Hi,
Is the following possible:
- let the ISE do the authentication and then proxy to another radius server which does the authorization.
At the moment we have a freeradius server that does the following:
1) authenticates 802.1x requests (eap-tls)
2) during authorization the server checks an external database that determines the vlan that should be returned (in radius attribute) based on originating switch and/or mac address.
I am checking if I can migrate to ISE but then the above would have to work.
For MAB I can easily do authentication/authorization on freeradius so I will proxy MAB requests to there.
regards
Thomas

ISE acts as a RADIUS proxy server by proxying the requests from a network access device (NAD) to a RADIUS server. The RADIUS server processes the request and returns the result to Cisco ISE. Cisco ISE then sends the response to the NAD
FYI
you can use the RADIUS server sequences to proxy the requests to a RADIUS server.
The RADIUS server sequence strips the domain name from the RADIUS-Username attribute for RADIUS authentications. This domain stripping is not applicable for EAP authentications, which use the EAP-Identity attribute. The RADIUS proxy server obtains the username from the RADIUS-Username attribute and strips it from the character that you specify when you configure the RADIUS server sequence. For EAP authentications, the RADIUS proxy server obtains the username from the EAP-Identity attribute. EAP authentications that use the RADIUS server sequence will succeed only if the EAP-Identity and RADIUS-Username values are the same.

Documentation for ISE RADIUS messages?

In ISE, clicking on Operations => Authentications, => Show Live Authentications brings up a list of authentication attempts. Clicking on Details on any one of the attempts brings up a list of authentication steps, each of which has an ID number and a description:
11001          Received RADIUS Access-Request
11017          RADIUS created a new session
15049          Evaluating Policy Group
15008          Evaluating Service Selection Policy
15048          Queried PIP
15048          Queried PIP
15004          Matched rule
11507          Extracted EAP-Response/Identity
12300          Prepared EAP-Request proposing PEAP with challenge
etc.....
Is there a document that describes these messages? I am a newb at this and I am unable to find anything.
Thanks,

ISE RADIUS authorization NX-OS

Anybody could confirm if RADIUS authorization is not supported on NX-OS?
If it's not supported, how should it be configured with ISE once ISE doesn't support TACACS?
NX-OS(config)# aaa authorization config-commands default group radius local
Radius group is not supported for command authorization
could not update aaa configuration

Jan is correct, you can't configure NX-OS based device the same way you would IOS based one when it comes to AAA. NX-OS devices do not "understand" privilege level. Instead, they use RBAC (Role Based Access Control). As a result, you have to return a shell role from your Radius server:
shell:roles=user_role
For more info take a look at the latest "NX-OS Security Configuration Guide" or this link:
http://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/6_x/nx-os/security/configuration/guide/b_Cisco_Nexus_7000_NX-OS_Security_Configuration_Guide__Release_6-x/b_Cisco_Nexus_7000_NX-OS_Security_Configuration_Guide__Release_6-x_chapter_0110.html#task_1074483

ISE Radius device administration authentication possible?

Hi,
does anybody know if Radius device administration authentication and authorization is possible with the actual ISE release? I know that TACACS will be available in future release.
Regards
Joerg

Yes it's possible according to "Ask the experts" forum :
https://supportforums.cisco.com/thread/2172532
"If you use RADIUS for device administration, ISE can be utilized using authorization policy elements that return Cisco av-pairs. But personally, I think ACS is currently superior to ISE for this task."
Anyway, I'm about to test "device admin" and "network access" simultaneously in the same switch with Radius and ISE.
Please rate if it helps

ISE : Radius Request Drop

I've implementing cisco ise. But i got something weird. The communication cisco ise and switch has down about 1 hours, and when i check on monitoring, the report just said Radius Request Drop. The communication is good before this happening. Do you know what is happen?
Regards,
Gandhi

I think the problem has solved now.
But, what i want to know is what is happening, there is a bug on Cisco ISE?
