ISE and WLC for CWA (Central Web Auth)

Hello All,
As we know that WLC (i.e. 5508) does not support MAB (MAC Auth Bypass) and it supports CWA in 7.2.x.
CWA is a result of successfull MAB. So how CWA work for wireless? So it means WLC support MAB?

I've been playing around with this and have it working on 7.3.101 on the WLC 5508, however, I don't seem to be receiving the web redirect correctly. When I look under the client connections on the WLC I see that the URL is received on the WLC from ISE, but it appears to be truncated, unless that's just a limitation of the display. I see hits on the ACL-WEBAUTH-REDIRECT ACL on the controller, but it doesn't seem to be redirecting. I have this similar configuration on the wired side of the house and it works fine. ISE just shows pending webauth, as it should.

OSX 10.10.1 with Cisco ISE guest portal using (CWA) central web authentication issue

We have Cisco Wireless with ISE (Identity Service Engine) to provide guest access with CWA (central web authentication). The idea is to provide guest access with open authentication, so anyone can connect. Then when the guest trying to browse the internet it will be redirected to guest protal for authentication. So only corporate guest with valid password can pass the portal authentication. This is been working fine for windows machine, android, and apple devices with earlier OS version (working on OSX 10.8.5). For clients that's been upgraded to OSX 10.10.1 or IOS 8 they can no longer load the CWA redirection page.
Please let us know if there's any setting under the OSX to solve the issue, or plan from apple to fix the issue on the next OSX/IOS release ?
thanks - ciscosx

Robert,
Manual assignment has been made available in ISE 1.2 release.

ISE and WLC for posture remediation

Please can anybody clarify a few things in relation to ISE and wireless posture.
1) Is the ACL-POSTURE-REDIRECT used for remediation, or is it just an ACL to redirect only some traffic to kickoff posture checking?
2) Can/Should a dACL/wACL be specified as a remediation ACL?
3) Do the WLC ACLs have to be written in long format (manually specifying source and dest ports/doesny direction any work?)
4) Does anybody have working example ACLs for posture redirect (cpp) and remediation (dACL)?
5) Any other advice or pointers would be helpful too as no docs i have found so far, be it TrustSec2, CiscoLive or anything else, dont seem to help me understand WLC posture and remediation
thanks
Nick

Nick,
Answers are inline:
1) Is the ACL-POSTURE-REDIRECT used for remediation, or is it just an ACL to redirect only some traffic to kickoff posture checking? This is for both (if ports 8905..are included) then this is for initial redirection, and remediation
2) Can/Should a dACL/wACL be specified as a remediation ACL? Wireless does not support DACL, you will have to reference another ACL in the the authorization policy, the new versions have the Airespace ACL field, where you will have the ACL defined locally on the wlc.
3) Do the WLC ACLs have to be written in long format (manually specifying source and dest ports/doesny direction any work?) Yes you have to add two entries, for example for all traffic redirection to ise...source = any, destination=iseipadd, source port=any, destination port=any direction=any action=permit
source=iseipaddr, destination ip = any, source port=any, destination port=any, direction=any action permit. Its not the easiest but I will attach a screenshot that will show you my example.
4) Does anybody have working example ACLs for posture redirect (cpp) and remediation (dACL)? ISE doesnt support DACLs so when you build your authorization profile in ISE you select the web authentication type (Posture Discovery) after that the ACL field will come up, there you will "call" the posture ACL which is defined on your controller.
5) Any other advice or pointers would be helpful too as no docs i have found so far, be it TrustSec2, CiscoLive or anything else, dont seem to help me understand WLC posture and remediation Keep in mind that you have to have radius NAC and AAA override enabled under the advanced settings for COA to work.
You have to turn on COA under the global settings in ISE (Administration > Profiling > Coa Type > Reauth)
Then you have to build your policies so that when a user connects to the network they are redirected to the download the nac agent (this is where the Posture Discovery and redirect ACL work in tandem).
Once the client download the nac agent and is compliant the report is forwarded to ISE where a COA event is triggered.
Then the client will reauthenticate and will hit another policy that will give them access once their machine is compliant, you can set the ACLs for restricted access, use dynamic vlan assignment, or just send the access-accept.

Central Web Auth with Anchor Controller and ISE

Hi All
I have a 5508 WLC on the corporate LAN and another 5508 sat in a DMZ as an anchor controller.
I also have an ISE sat on the corporate LAN.
Authenticate is working fine to the ISE and the client tries to re-direct to the ISE Portal but doesn't get there.
DNS is working fine and the client can resolve the URL of the ISE to the correct IP address.
I have a redirect ACL configured on the foreign controller which permits DNS, DHCP and traffic to and from the ISE.
My questions are:
1. Do I need to re-direct ACL to be present on both the foreign and anchor controllers?
2. Since the Radius requests originate from the foreign controller do I need to configure the ISE server address on the WLAN on the anchor?
3. Does the re-direct ACL need to be enabled on the advanced page of the WLAN on the foreign to over-ride the interface ACL - I don't believe it does.
4. Is ICMP still blocked by the WLC until the web authentication is complete?
Thanks.
Regards
Roger

Hi Roger,
Thanks for your brief explanation here are the answers for your queries.
1. Do I need to re-direct ACL to be present on both the foreign and anchor controllers?
The only catch is that since this web authentication method is Layer 2, you have to be aware that it will be the foreign WLC that does all of the RADIUS work. Only the foreign WLC contacts the ISE, and the redirection ACL must be present also on the foreign WLC.
2. Since the Radius requests originate from the foreign controller do I need to configure the ISE server address on the WLAN on the anchor?
Yes, you have to configure the ISE server address on the anchor WLC.
3. Does the re-direct ACL need to be enabled on the advanced page of the WLAN on the foreign to over-ride the interface ACL
Yes, you should override AAA under advanced tab of WLAN as ACL will be present on the foreign WLC.
4. Yes, ICMP will work only after the sucessful web auth is complete.
Please do go through the link below to understand the Anchor-Foreigh Scenario.

ISE and WLC SRE module compatibilty matrix

Hi all,
We are running SRE module on router with code of 6.x release .Is there any compatibilty matrix available for ISE and WLC code to support CWA . because as of now , the wireless clients are not redirecting to the ISE login page.
Kindly suggest.
Thanks,
Regards,
Vijay

The doc is for wireless guest using CWA. For wired guest, I don't know since you can do wired guest from a WLC that supports it or from a switch.

ISE and WLC

Dear friends,
We are using ISE and WLC integrity in our network, we have Corporate and Guest SSID, we configured it but client cant connect to this ssid and cant be authenticated, please see attached files and tell me if i done something wrong in configuration of WLC
10.10.17.201 is ISE
Thank you for attention

Hi,
After viewing the Trap logs it seems you have checked on validate machine.
On the client side, make sure you don't check validate machine and then try.

WLC 7.5 Sleeping clients with ISE and Central WEB Auth(CWA)

Hi there,
Is it possibe to use sleeping clients when using ISE and CWA?
I was thinking of enabling layer3 auth with web auth on mac auth failure, but will that work with CWA?
Or is the only solution to use LWA?

Controller-> General-> User Idle Timeout (seconds) = 50 000 sec.
And your users will be connected all this time even if they going in sleepmode
be carefull with CPU loading

LWA Guest Access with ISE and WLC

Hi guys,
Our Company try to implement Guest Access with ISE dan WLC with Local Web Auth Method. But there is problem that comes up with the certificate. This is the scenario :
1. Guests try to connect wifi with SSID Guest
2. Once it connect, guests open the browser and try to open a webpage (example: cisco.com)
3. Because, guests didn't login, so it redirect to "ISE Guest Login Page" (url became :
https://ise-hostname:8443/guestportal/Login.action?switch_url=https://1.1.1.1/login.html&wlan=Guest&redirect=www.cisco.com/
4. If there is no ISE Guest Login Page installed, message Untrusted Connection message will appear, but it will be fine if they "Add Exception and install the certificate"
5. After that the Guest Login Page will appear, and guests input their username and password.
6. Login success and they will be redirected to www.cisco.com and there is pop up from 1.1.1.1 (WLC Virtual Interface IP) with logout button.
The problem happen in scenario 6, after login success, the webpage with ISE IP address and message certificate error for 1.1.1.1 is appear.
I know it happened when guests didn't have the WLC Login Page Certificate...
My Question is, is there a way to tunneling WLC Certificate on ISE ? Or what can we do to make ISE validate WLC Certificate, so guests doesn't need to install WLC Certificate/ Root Certificate before connect to Wifi ?
Thx 4 your answer and sorry for my bad English....

Thx for your reply Peter, your solution is right,
i don't choose CWA, because their DNS is not stable...
i've found the problem...
the third-party CA is revoked, so there is no way it will success until it fixed...
and there is no guarantee, they will fix it soon..
so solution that we choose is by disable "HTTPS" on WLC...
"config network web-auth secureweb disable".
"config network web-auth secureweb disable".
"config network web-auth secureweb disable".
"config network web-auth secureweb disable".
"config network web-auth secureweb disable"
thank you all...

Cisco ISE and WLC Timeout Best Practices

I am fairly new to ISE. Our Cisco WLC is using 802.1x and ISE is configured for PEAP with all inner methods enabled.
I am looking for some guidance around where I should be configuring timeouts. There is a PEAP Session timeout in ISE, a session timeout on the WLC and a RADIUS reauthentication timeout that can be set in the Authorization profile results object in ISE.
Currently I have the WLC configured for its default 1800 second timeout and ISE PEAP timeout at the default 7,200 value.

I ended up answering my own question. The authorization session timeouts should be set in ISE if at all.
Once I removed the session timeout value from the WLC and used the re-auth value in the ISE policy I had less complaints about disconnects.
The session timeout on the PEAP settings has not caused any ill affects at it's default. The session resume has taken a huge load off of AAA though. Its worth turning on.

Cisco ISE and WLC Access-List Design/Scalability

Hi,
I have a scenario whereby wireless clients are authenticated by the ISE and different ACLs are applied to it based on the rules on ISE. The problem I seems to be seeing is due to the limitation on the Cisco WLC which limit only 64 access-list entries. As the setup has only a few SVI/interfaces and multiple different access-lists are applied to the same interface base on the user groups; I was wondering if there may be a scalable design/approach whereby the access-list entries may scale beside creating a vlan for each user group and applying the access-list on the layer 3 interface instead? I have illustrated the setup below for reference:
User group 1 -- Apply ACL 1 --On Vlan 1
User group 2 -- Apply ACL 2 -- On Vlan 1
User group 3 -- Apply ACL 3 -- On Vlan 1
The problem is only seen for wireless users, it is not seen on wired users as the ACLs may be applied successfully without any limitation to the switches.
Any suggestion is appreciated.
Thanks.

Actually, you have limitations on the switch side as well. Lengthy ACLs can deplete the switch's TCAM resources. Take a look at this link:
http://www.cisco.com/c/en/us/support/docs/switches/catalyst-3750-series-switches/68461-high-cpu-utilization-cat3750.html
The new WLCs that are based on IOS XE and not the old Wireless/Aironet OS will provide the a better experience when it comes to such issues.
Overall, I see three ways to overcome your current issue:
1. Shrink the ACLs by making them less specific
2. Utilize the L3 interfaces on a L3 switch or FW and apply ACLs there
3. Use SGT/SGA
Hope this helps!
Thank you for rating helpful posts!

ISE and critieria for quarantine

We have a question concerning ISE and what criteria it is able to use when placing an enpoint into quarrantine. We would like to configure ISE to quarrantine systems that have been placed on a network other than our business network. In other words, we're wondering if ISE is able to detect whether one of our systems has been on another network (for example: it has been connected to a users' home network). Can ISE do this, quarantining the system until security scans can be completed?
Thank you for any information that you can provide

Is ASA integration with ISE and RSA for 2 factor authentication a valid/tested design

Hi,
Customer currently uses ASA to directly integrate with RSA kind of solution to provide 2 factor authentication mechanism for VPN user access. We're considering to introduce ISE to this picture, and to offload posture analysis from ASA to ISE. And the flow we're thinking is to have ASA interface to ISE and ISE interface to RSA and AD backend infrastructure. And we still need the 2 factor authentication to work, i.e., customer gets a SMS code in addition to its login username and password. I'm wondering if ASA/ISE/RSA/AD integrated solution (and with 2 factor authentication to work) is a tested solution or Cisco validate design? Any potential issue may break the flow?
Thanks in advance for any input!
Tina

Hi,
I have an update for this quite broad question.
I have now came a bit further on the path.
Now the needed Radius Access Attribute are available in ISE after adding them in
"Policy Elements" -> "Dictionaris" -> "System" -> "Radius" -> "Cisco-VPN3000".
I added both the attribute 146 Tunnel-Group-Name which I realy need to achive what I want(select diffrent OTP-backends depending on Tunnel Group in ASA) and the other new attribute 150 Client-Type which could be intresting to look at as well.
Here the "Diagnostics Tools" -> "Generel tools" -> "TCP Dump" and Wireshare helped me understand how this worked.
With that I could really see the attributes in the radius access requests going in to the ASA.
Now looking at a request in "Radius Authentication details" I have
Other Attributes:
ConfigVersionId=29,Device Port=1025,DestinationPort=1812,RadiusPacketType=AccessRequest,Protocol=Radius,CVPN3000/ASA/PIX7.x-Tunnel-Group-Name=SMHI-TG-RA-ISESMS,CVPN3000/ASA/PIX7.x-Client-Type=,CPMSessionID=ac100865000006294FD60A7F,.....
Ok, the tunnel group name attribute seems to be understood correct, but Client-Type just say =, no value for that.
That is strange, I must have defined that wrong(?), but lets leave that for now, I do not really need it for the moment being.
So now when I have this Tunnel-Group-Name attribute available I want to use it in my Rule-Based Authentication Policy.
Problem now is that as soon as I in an expression add a criteria containing Cisco-VPN3000:CVPN3000/ASA/PIX7.x-Tunnel-Group-Name matches .* (just anything), then that row does not match any more. It still work matching against NAS-IP and other attributes.
What could it be I have missed?
Best regards

Customised look and feel for B2B/B2C web shop.

Dear experts,
I would like to find out if there is an admin page for SAP E-commerce to customise the look and feel of the webshop?
Thanks.
Wein

Hi Wein,
To change Look and Feel for Web shop is depends on scenario of eCommerce application i.e. B2B or B2C. B2B has different structure than B2C.
Web Channel application comes in SAP standard with SAP look and Feel. You have to change look and feel as per client requirement.
To change look and feel of Both B2B/B2C scenario you have to deal with files like CSS, JSP, Properties, XLF and some time you have to add your custom JAVA, JSP, CSS, Properties files etc...
To change standard SAP logo youhave to make change in CSS files. Also you have to consider Browser type while changing look and feel because to display your B2B/B2C application correctly in different browser you have to make changes in different CSS.
You will get better idea with example how to change look and feel in "Dev & Ext. Guide" for Web Shop. You will get this from Service Market place.
