Cisco ISE and WLC Access-List Design/scalability

Hello

I have a scenario that wireless clients are authenticated by the ISE and different ACL is applied depending on the rules in the ISE. The problem I have seen is due to the limitation on the Cisco WLC that limit only 64 input access list. As the installer has only a few IVR/interfaces and several different access lists are applied to the same base on user groups interface; I was wondering if there may be an evolutionary design / approach according to which the access list entries can evolve next to create a vlan for each group of users and apply the access list on the interface of layer 3 instead? I illustrated the configuration below for reference:

Group of users 1 - apply ACL 1 - on Vlan 1

User 2 group - apply ACL 2 - on the Vlan 1

3 user group - apply ACL 3 - on the Vlan 1

The problem appears only for wireless users, he does not see on wired users as the ACLs can be applied successfully without restriction as to the switches.

Any suggestion is appreciated.

Thank you.

In fact, you have limitations on the side of the switch as well. Long ACL can deplete resources AAGR of the switch. 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 based on IOS XE and not the old OS Wireless/Aironet will provide the best experience in these matters.

Overall, I see three ways to overcome your current number:

1. reduce the ACL by making them less specific

2 use L3 interfaces on a switch L3 or FW and the ACL is applied to them

3. use the SGT/SGA

I hope this helps!

Thank you for evaluating useful messages!

  • Cisco ISE and Meraki RADIUS

  • Guest access with ISE and WLC LWA

    Hi guys,.

    Our company try to implement access as guest with dan ISE WLC with the local Web authentication method. But there is problem that comes with the certificate. This is the scenario:

    1. the clients are trying to connect wifi with guest SSID

    2. once it connects, you can open the browser and try to open a Web page (example: cisco.com)

    3, because guests didn't connect, so this link redirect to "ISE Guest Login Page" (become): url

    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 Login to ISE not installed comments Page, no reliable connection of message message, but it will be fine is they "Add Exception and install the certificate".

    5. once the Guest Login Page will appear and you can enter their username and password.

    6 connection success and they will be redirected to www.cisco.com and there pop-up 1.1.1.1 (IP of the Virtual Interface WLC) with the logout button.

    The problem occur in scenario 6, after the success of the opening session, the Web page with the address and the error of certificate ISE IP to 1.1.1.1 is appear.

    I know that it happened when you can has no Page of Login of WLC certificate...

    My Question is, is there a way of tunneling WLC certificate to EHT? Or what we can do for ISE validate certificate WLC, invited didn't need to install the certificate WLC / root certificate before you connect to the Wifi?

    THX 4 your answer and sorry for my bad English...

    Do not mix WLC with ISE comments Portal local Web authentication. Choose one or the other. I suggest the portal + WLC CWA.

    Dear,

    I created a list of access-pre approval for cisco ise 1.4, depending on the Switch Configuration required to Support Cisco ISE 2.0 functions, properly profiled Cisco IP phone and download a good list of permit ip access IE, but when I make a PSTN call I hear a one-way audio, when I see the switch connects it show me that RTP has been blocked by default access-list , I have a question when my DACL list is downloaded correctly then why the default ACL is interrupting the RTP, also I see the port number 2000 & 2443 is blocked by default access-list by phone losses its connection to the server, which are used to to the CUCM keepalive.

  • Critical auth and limited access-list

    I play just with ISE 1.1.4 and auth critical, but I have a pretty locked down from the default access on ports list. Is it possible to replace a list of very restrictive access by default in the event of critical auth?

    It seems as if you are relieant on DACLs to provide access for devices (closed or similar mode) auth criticism is not a viable option?

    Or have I misunderstood, and perhaps "action dead event server authentication allows voice" more I waited.

    I guess I'm looking for something like "event action dead access-list less-restrictiveACL server authentication."

    Thank you

    Gas

    Why not flip it on its head and have your less-restrictive-ACL default and impose more restrictive things through dACL?

  • ISE and WLC for sanitation of the posture

    Please can someone clarify a few things regarding the ISE and posture wireless.

    (1) is the ACL-POSTURE-REDIRECT used for conversion, or is it just an ACL to redirect some of the posture of the kickoff checking traffic?

    (2) can / a dACL/wACL list must be specified as a sanitation ACL?

    (3) the WLC ACL should be written in long format (manually specify source and dest ports/doesny direction any job?)

    (4) does anyone have working example ACL for redirect (CPC) posture and sanitation (dACL)?

    (5) any other advice or pointers would be as useful as any docs I have found so far, what he TrustSec2, CiscoLive or anything else, do not seem to help me understand sanitation and WLC posture

  • Cisco ISE and external syslog server

    Hi Security Experts,

    We start with deployment cisco ISE (Identity Services Engine) in our network. We have allocated 250 GB of space for the node (Admin + monitor) ISE.

    I want to know if we can send tracking of nodes of external syslog server logs after a defined time interval.

    For example, newspapers that are more than 10 days are for external syslog server. So basically our node monitoring will have the marbles which are the Max 9 days. Is this possible? Could you tell me some doc that explains the configuration of the same thing?

    Thank you

    Boudou

    No this is not possible via syslog. What you need is database purge, so that the monitoring database is purged after a determined time interval. Here's a guide that will help shed some light on this:

  • Cisco ISE and the fast user switching

    Greetings,

    In our deployment, we are interested in using the "fast user switching" which lies in the functionality of Windows.   After searching for a while, I see that the native Windows supplicant is not compatible with the fast user switching.   It does not appear that Anyconnect is either.   Can you please inform me as to what suppluicant, I need research to enable the functionality of Switchign user?

    We currently use ISE 1.2 Patch 4.

    Thank you for any assistance.

    David

    Cisco EHT NAC Agent does not support Windows fast user change when you use the native supplicant. This is because there is not clearly the older user disconnecting. When a new user is sent, the Agent is hung on the ID process and the old user session and therefore a new posture cannot take place. According to Microsoft Security policy, it is recommended to disable the fast user switching.

  • ISE and WLC for CWA (Web Central Auth)

    Hi all

    As we know that WLC (i.e. 5508) is intolerant of MAB (MAC Auth Bypass) and it supports CWA in 7.2.x.

    CWA is the result of successful MAB. So, how CWA to work for the wireless? So that means WLC support MAB?

    Hello

    The term in the wireless world is mac filtering. When mac filtering is fired, you will return the CWA portal in the access-accept.

    Don't forget to set your condition in the authentication policy to continue if the user is not found, while the device can hit the CWA default rule.

    Thank you

  • Cisco ISE and question Admin CLI

    Hello.

    I have a strange problem with my installation of ISE. First of all, I use AD users for authentication. It works very well on HTTPS. I can connect with my admin AD by HTTPS.

    The problem starts when I try to log in via the CLI (SSH). I got login prompt. When I type my credentials AD that he said "Login Incorrect" and I got the same result if I try it with the local administrator account.

    I tried to reset the password for the local administrator over HTTPS to check this kind of wrong password. But no effect.

    My ISE is installed VMware.

    Experiences with it?

    ARM

    CLI authentication which is the base Linux OS is not / cannot be bound to AD to the admin authentication. Only, you integrate the application on top of Linux, which in this case is ISE, to AD. So, if you want to connect to the cli shell, you will need to use the username/password you configured during installation. If you do not remember those you need to perform a rest of password via the installation CD / ISO

  • Cisco ISE and the new Version of AntiVirus... not DAT

    I am ready to go to our VPN ISE users. It was a great test and it seems that we are ready to roll.

    Then comes a new version of our corporate AntiVirus software. We had Kaspersky EndPoint Security v8 since last August. Kaspersky now comes to Endpoint Security v10. It took about 3 months for compliance in ISE Module to allow the NAC Agent to recognize KESv10. But now, when we connect I get an error from the NAC stating bascially that the version of installed KES is no posture installation rules and he can't do anything. (see attachment for the exact wording)

    I remember when we first set up the ISE, there was a screen that broke down the different manufacturers of AV and the different versions that would support ISE/NAC. I have no idea where it is now.

    How to I update my sanitation/policies/rules to take account of two KES10 including, or simply change to allow version 8 +, or even ANY version?

    I'm sure this is a simple solution, but I can't find it. I looked through a lot of documentation, and I even looked through a PDF of global laboratory on-site ISE posturing, and he can find.

  • Authentication (Windows Server 2013) AD Cisco ISE problem

    Background:

    Has deployed two Cisco ISE 1.1.3. ISE will be used to authenticate users wireless access admin WLC and switches. Database backend is Microsoft running on Windows Server 2012 AD. Existing Cisco ACS 4.2 still running and authenticate users. There are two Cisco WLCs version 7.2.111.3.

    Wireless users authenticates to AD, through works of GBA 4.2. Access admin WLC and switches to the announcement through ISE works. Authentication with PEAP-MSCHAPv2 access and admin PAP/ASCII wireless.

    Problem:

    Wireless users cannot authenticate to the announcement through ISE. This is the error message '11051 RADIUS packet contains invalid state attribute' & '24444 Active Directory failed because of an error that is not specified in the ISE'.

    Conducted a detailed test of the AD of the ISE. The test was a success and the result seems fine except for the below:

    Log Cisco ISE and WLC by using the credentials of the AD. This excludes the connection AD, clock and AAA shared secret as the problem.

    (2) wireless authentication tested using EAP-FAST, but same problem occurs.

    (3) detailed error message shows below. This excludes any authentication and authorization policies. Even before hitting the authentication policy, the AD search fails.

    (9) notes of verified version of ISE 1.1.3 and WLC 7.2.111.3 for any open caveats. Find anything related to this problem.

    10) there are two ISE and two deployed WLC. Tested a different combination of ISE1 to WLC1, ISE1 to WLC2, etc. This excludes a hardware problem of WLC.

    Other possibilities/action:

    1) test it on another version WLC. Will have to wait for approval of the failure to upgrade the WLC software.

    (2) incompatibility between Cisco ISE and AD running on Microsoft Windows Server 2012

    Did he experienced something similar to have ideas on why what is happening?

    Thank you.

    Update:

    (1) built an another Cisco ISE 1.1.3 sever in another data center that uses the same domain but other domain controller. Thai domain controller running Windows Server 2008. This work and successful authentication.

    (2) my colleague tested in a lab environment Cisco ISE 1.1.2 with Windows Server 2012. He has had the same problem as described.

    This leads me to think that there is a compatibility issue of Cisco ISE with Windows Server 2012.

  • Question of access list for Cisco 1710 performing the 3DES VPN tunnel

    I have a question about the use of access lists in the configuration of a router Cisco 1710 that uses access lists to control traffic through the VPN tunnel.

    For example the following lines in a configuration on the remote router. My question is whether or not the traffic that matches the definition of list access-130 (something other than 192.168.100.0/24), cross the VPN tunnel or go directly to the Ethernet0 interface.

    My understanding is that traffic that matches the access list 120 would be encrypted and sent through the IPSec tunnel. If there was "ban" set out in the statements of 120 access-list, the traffic for those would be sent through the IPSec tunnel but not encrypted (if possible). And finally, given that the definition of crypto card reference only "adapt to 120", any traffic that matches 130 access list would be sent Ethernet0 but not associated with the card encryption and thus not sent through the IPSec tunnel. "

    Any input or assistance would be greatly appreciated.
