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!

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.

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.

Clienless webvpn and reflexive access list firewall

I have a Cisco Router 3825 with WEBVPN server and Reflexive access list Firewall. All is well but when i try from outside to go to WEBVPN server and try trought WEBVPN site to open some web Site it dosen`t work. For example when i try to open yahoo.com, the log shows
"%SEC-6-IPACCESSLOGP: list ACL-FILTER-IN denied tcp 98.138.253.109(80) -> my_ip_address(45341), 1 packet [ACL_ERROR]"
98.138.253.109 is yahoo.com ip address
Can you give my advice how to solve this problem?

If you have WEBVPN, then you have the Security-image/license on your router. That means that you are not restricted to reflexive ACLs, you can use a "real" firewall-feature like CBAC or ZBF on that device.

I have a 3rd generation iPod Touch and just did the update to IOS 5. Now I can't connect to my Netgear wifi router. My iPhone connects fine along with all of my other laptops etc. I have the router set with WPA-PSK [TKIP] security and an access list.

I have a 3rd generation iPod Touch and just did the update to IOS 5. Now I can't connect to my Netgear wifi router. My iPhone connects fine along with all of my other laptops etc. I have the router set with WPA-PSK [TKIP] security and an access list. I've confirmed the mac address is included on that list and that the password is correct. Under choses netwrok I select the network and it just goes into a spin. I have tried removing the password and the access list settings and it still will not complete the connection to the router thus no internet access. The routers firmware is also up to date. This thing worked fine before this update and I've already tried to restore from backup. Any ideas or is the wifi nic bad in this thing with the new apple firmware update? Any fix?

Thanks Bob, I don't know why but it all of a sudden worked a few days later. It's a mystery but at least problem solved.

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.

OOPS !!
I will repost the whole messaqge with the correct external URL's:
In general, the Trustsec design and deployment guides address the specific support for the various features of the 'whole' Cisco TS (and other security) solution frameworks. And then a drill-down (usually the proper links are embedded) to the specifc feature, and then that feature on a given device. TS 2.1 defines the use of ISE or ACS5 as the policy server, and confiugration examples for the platforms will include and refer to them.

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 SecurID Integration Questions

I'm looking for some clarity trying to understand something conceptually. I want to integrate Cisco ISE with RSA SecurID, the idea being that if the user authenticates with RSA SecurID they end up on one VLAN, however, if they don't authenticate with (or don't use, or don't have) SecurID they'll end up on another VLAN. Note that I'm not using SecurID for wireless access...all PCs are wired to Ethernet.
We have been using RSA SecurID for a while and are currently on version 8.0. Our users are authenticating via the RSA Agent typically on Windows 8.1. Instead of the usual Windows login prompt, the RSA Agent first prompts for the username and passcode (they use an app on their smartphones to get the passcode), then after a moment or two, it prompts for their Windows domain password.
We have recently installed Cisco ISE version 1.3. With the help of a local Cisco engineer and going through the "Cisco Identity Services Engine User Guide", I have it set up and running along with a few 'test' ports on our Cisco 6809 switch, it basically works...as a test it's simply set up that if they authenticate they're on one VLAN, if not, they end up on another (this is currently without using RSA...just out-of-the-box Windows authentication).
The Cisco engineer was unable to help me with RSA SecurID, so pressing on without him, out of the same user guide I have followed the directions for "RSA Identity Sources" under the "Managing Users and External Identity Sources", and that went well as far as ISE is concerned; I am now ready to get serious about getting ISE and SecurID working together.
My mistake in this design so far was assuming that the RSA agent on the Windows client PCs would communicate with Cisco ISE...there doesn't seem to be a way to have them point to a non-RSA SecurID server for authentication. The concept I'm missing is what, or how, the end-user machine is supposed to authenticate taking advantage of both ISE and SecurID.
I have dug deeper into the Cisco ISE documentation but it seems heavily biased towards Wi-Fi and BYOD implementations and it's not clear to me what applies to wired vs wireless. Perhaps it's a case that I'm not seeing the forest for the trees, but I'm not understanding what the end-user authentication looks like. It apears that as I learn more about ISE, it should become the primary SSO source, that SecurID becomes just an identity source and the PC clients would no-longer directly communicate with the SecurID servers. That being the case, do I need to replace the SecurID client on the PCs and something else Cisco-ish fills this role? An agent for ISE? How do they continue to use their passcode without the RSA agent?
Thanks!

The external db not operation indicates that there is no communication between ACS and RSA. Did you fetch the package.cab file to analyse the auth.log file?
Have you already gone through the below listed link?

Cisco ISE Block URL Access

Hello, Everyone
Is there a way to deny access to an URL in Cisco Identity Services Management. I want to deny all users http accesses to the default Portal
"https://<ip_of_ise>:8433/guestportal/Login.action".
This URL is redirecting the users to the DefaultGuestPortal.
Thank you For help.

For this question according to my understanding to do this task usually we use Authorization policy to restrict access by using downloadable ACL (or even by VLAN) , We have “Webtype” ACL(ostname(config)# access-list acl_company webtype deny url http://*.company.com) but these type of ACL are not supported on Switch I guess , they are for 5500 ASA. So this is not possible using ISE but Iron Port can be used for the same and customer’s requirement can be meet. Please follow the link below it may be of Help

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.

Inline Posture between Cisco ISE and Wireless LAN Controller

Hi,
I was looking into Cisco ISE solution for deploying NAC.
I have a question about the network topology.
In the user guide documents of cisco ISE, it is written that for Wireless LAN Controllers (WLC) and VPN devices, an additional server, Inline Posture, is needed.
However, in the following integration document, there is not an inline posture between WLC and Cisco ISE server.
https://supportforums.cisco.com/docs/DOC-18121
I want to know if Inline Posture is a requirement, if not a requirement, what are the benefits of having it between Cisco ISE Server and WLC.
Thanks & Regards

Cisco ISE and authentication for 802.1x printer

Hello
What is the best practice to authenticate a 802.1x printer in Cisco ISE?
The printer can store a certificate for authentication and support EAP-TLS.
Thanks for answer.
Marco

EAP-TLS is the way to go. It is way way way more secure than MAB and profiling. However, the question is "How much of a hassle is it going to be to put a certificate on each printer?" Moreover, "What methods do I have (if any) to renew those certificates when they expire?" If have to manually generate a CSR and install a cert on each printer then it can quickly become an administrative overhead nightmare. With that being said, you can use MAB and profiling but just make sure that you lock down the access that those printers get. For instance, do they need access to the internet? Do they need access to anything else but the print server and/or open to all IPs access but only on the printing ports.
I hope this puts you in the right direction!
Thank you for rating helpful posts!

Cisco ISE and forest trusts vs domain trusts

Hi All,
Is there any issues with forest trusts with Cisco ISE ?
I have a customer that had external trusts and ISE was working ok for PEAP MSChapv2 user auth across domains.
They recently removed external trusts and changed to forest trusts. Now auth doesn't work. Initial error was authc ok, authz fail.
I can search and get lists of AD groups ok for the remote domain.
Using the attribute tab, I can't get attributes for users in remote domain. I'm thinking since I can't see the memberof attribute, none of my authz pollicies will work.
I have done "leave" and "join" domain again.
In my lab, I have forest trusts and it actually works ok. A previous poster talked about kerberos issues across forest trusts ?
Cheers
Peter.

Cisco ISE and Switch 3560-X

Good Morning,
I am conducting an implementation of Cisco ISE version 1.2.1.198 with all its features on a switch 3560-X and in the ISE compatibility chart the minimum version for this switch would be the IOS v 15.0.2-SE2 (ED).
My doubt is whether i need the feature ipbase or just the lanbase would be sufficient to meet all the features of 802.1x for the Cisco ISE.
I appreciate the attention and Thanks,

Please see the "Cisco Secure Access and Cisco TrustSec Release 5.0 System Bulletin".
It notes that the 3560-X requires IP base license for all the 802.1X features.
