Wlc flexconnect wlan local authentication and central web authentication maximum rtt

Hi
From the below link below it mentioned that "Round-trip latency must not exceed 300 milliseconds (ms) between the AP and the controller. If the 300 milliseconds round-trip latency cannot be achieved, configure the AP to perform local authentication."
http://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Mobility/emob73dg/emob73/ch7_HREA.html#wp1094148.
Is this limitation refer to web authentication also?
Thanks
Anyone???

Central Web Auth (CWA) works different on controllers/APs running in FlexConnect mode. Please check this guide and confirm that you have similar setup.
http://www.cisco.com/c/en/us/support/docs/security/identity-services-engine/116087-configure-cwa-wlc-ise-00.html
If so, please post screen shots with your configs (Redirect ACLs, policies in ISE and the WLC SSD settings).
Also, the version of code that you are running in ISE and your controller.

ISE and central web authentication

Hello all,
I have followed the steps in this document in detail:
http://www.cisco.com/en/US/products/ps11640/products_configuration_example09186a0080ba6514.shtml
however, my central authentication does not work. I get to the guest portal, i get authenticated through the guest portal,
but then the "second" MAB authenticatino doesn't happen.
In the last screencapture of the document, you get a green "Dynamic Authorization" line (third line from below). On my system
this is a red line with the error message "11213 No response received from Network Access Device".
(i have a successfull guest authentication in my ise logs, but it seems ise is unable to bounce or initiate the second MAB....)
Any ideas ?
regards,
Geert

By the way, i feel the document example is a bit too general. For example, if you implement the document, ISE will do web authentication and redirection even when you are using a 802.1X client and are authenticated (and you have no other rules in your Autorization sequence table)
I managed to prevent this by adding an additional condition to the first rule "MAC not known" that has the CentralWebAuth policy. Only do webautentication if MAC not known AND Wired_MAB is being used.

Local Web Authentication Started after Central Web Authentication

Hi everyone,
We have a DMZ based anchor WLC for a guest WLAN. I have this WLAN configured for central web authentication using ISE 1.2, this works correctly and can login using the guest portal.
However, after logging when browsing to a website everything is redirected to the local web authentication page and the policy manager state for the client goes in to a WEBAUTH_REQD state. I currently don't have any layer 3 security configured for this WLAN, so from my understanding it should just be using the central authentication provided by ISE.
Thanks for your help.
Mark

Hi Mark,
Thanks - that looks very similar to ours, though I'm doing the 3850 via the CLI as the web UI keeps dying when I click into things.
I've realsed that I unticked the Authentication servers box instead of the Accounting as I miss-read the WLC page, however while the LWA no-longer kicks in, I'm unable to pass anything except DNS traffic. The Anchor says that the client is in "Webauth" state so it looks like it's expecting something, but ISE says it's all ok and I can see the 3850 traffic going through the process flow.
If I attach an AP to the WLC directly and have the accounting box ticked, then it all works exactly as I'd expect - this is just, well, odd....

Not Working-central web-authentication with a switch and Identity Service Engine

on the followup the document "Configuration example : central web-authentication with a switch and Identity Service Engine" by Nicolas Darchis, since the redirection on the switch is not working, i'm asking for your help...
I'm using ISE Version : 1.0.4.573 and WS-C2960-24PC-L w/software 12.2(55)SE1 and image C2960-LANBASEK9-M for the access.

Central web authentication

I have downloaded the new Cisco ISE, I've managed to configure 802.1x and MAB succesfully but I want to configure wired centralized web authentication, but I cannot find any documentation how to configure ISE and Cisco Catalyst (IOS) switches to use this feature (I only find (limited) documentation about local web auth on the switch).
I want to achieve the following authentication order on a switchport:
802.1x
MAB
central web authentication
So if a guest user comes with his laptop, 802.1x is not configured on his laptop and he's not in the Mac Bypass DB, he should "failover" to web auth and get the ISE guest portal webpage with his web browser. There he enters a guest username and password (which is of course already in the ISE DB) and he should get web access.
I've configured the switchport with the following commands
switchport access vlan 99
switchport mode access
switchport voice vlan 50
authentication event no-response action authorize vlan 32
authentication host-mode multi-domain
authentication order dot1x mab webauth
authentication port-control auto
authentication violation protect
authentication fallback webprofile
mab
dot1x pae authenticator
dot1x timeout quiet-period 2
dot1x timeout tx-period 2
spanning-tree portfast
spanning-tree bpduguard enable
the web-profile with access-list to permit DHCP traffic between the attached device and any DHCP server in the vlan 99, and communications with ISE (also in vlan 99) at the moment "fallback webprofile" is triggered (I don't know if this should be configured with central webauth?)
SW01T#sh fallback profile webprofile
Profile Name: webprofile
Description : webauth profile
IP Admission Rule : NONE
IP Access-Group IN: 133
FYI, the access list:
Extended IP access list 133
10 permit ip any host 10.175.0.29
30 permit udp any any eq bootps
40 permit udp any eq bootpc any
In the ISE, I configured DOT1x and MAB. In the MAB profile, I configured "continue" if user is unknown, and then an authorization profile for the web authentication:
(attributes of the profile):
Access Type = ACCESS_ACCEPT
cisco-av-pair = url-redirect-acl=webauth
cisco-av-pair = url-redirect=https://ip:8443/guestportal/gateway?sessionId=SessionIdValue&portal=https://10.175.0.29:8443/guestportal/gateway?sessionId=SessionIdValue&portal=http&action=cwa&action=cwa
But it doesn't work. If I attach a device, it tries 802.1x, it tries MAB, then it fails over to "web authentication" but immediately fails with "no-response" message:

Hi Tarik,
thank you for the fast reply.
I've configuried the extra settings you told me (although I thought the ip admission configuration was only for local web authentication (where the switch acts as a http server).
But it still doesn't work. The pc is getting the ip address from the dhcp server but if I open a browser session, I do not get redirected to the ISE portal in order to log me in with a Guest account.
If I look at the authentication session of the port, it looks like the ISE has correctly sent the redirect acl and redirect url to the switchport:
Switch# show auth sessions int fa 1/0/3
           Interface: FastEthernet1/0/3
         MAC Address: 0011.25d7.6c6c
          IP Address: 10.175.0.229

Runnable methods list:
       Method   State
       dot1x    Failed over
       mab      Authc Success
       webauth Not run
As you can see, the "web authentication" is the result of a "succesful MAB". This is because I had to configure ISE to continue on MAB if the user was not found (I found that somewhere in documentation). Then I have configured a default authorization profile where the "web authentication" is triggered. This is where I've configured the redirect-url and so on and this is of course sent to the switch as a succesfull MAB:
authorization profile "webauthentication" with the "centralized web authentication" settings configured (see attributes output):
Access Type = ACCESS_ACCEPT
cisco-av-pair = url-redirect-acl=webauth
cisco-av-pair = url-redirect=https://ip:8443/guestportal/gateway?sessionId=SessionIdValue&action=cwa
Actually, I really have no idea if I have correctly configured ISE to handle central web authentication...
If I check the "show ip admission cache", nothing is seen in there.

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.

Same wlan both locally switched and centrally switched

Scenario:
1 virtual wireless controller
50 access points, some of them some local to the controller (same site), other on remote sites, all in flexconnect mode.
Is there a way for a wlan to be locally switched for a group of ap's, essentialy those local to the controller, and centrally switched for other groups of ap's, in fact those placed on remote sites?
I've tried configuring flexconnect groups, and ap groups, but no luck, I've found no way to override the globally configured flag "flexconnec local switching".
I've also tried to create two identical wlans, one locally switched and the second globally switched, but the wlc refuses to activate the second one since it has the same ssid of the first one.
Regards,
Massimo.

Since you have vWLC all AP needs to be in FlexConnect mode (If you got a normal WLC you can keep HQ AP in local mode & Remote AP in Flex mode to achieve this)
I think in your case you have to either choose "Central Switching" or "local switching" for your APs.

WiSM and GUEST web authentication

I have a WiSM and we use Cisco open web
authentication with a user email address.
When performing this command via CLI:
>config network secureweb disable
>save config
> reset system
Will this make the web authentication come up HTTP instead of HTTPS ?

That command is in order that you manage the unit.
However there used to be a workaround that when you disable HTTPS and SSH and you reboot the WLC the web authentication will be showed as http and no https.
Let me know if it works for you

ISE Wired Central Web Authentication no url redirect

We are setting up ISE for wired guest accest but are having trouble with the client being redirected. The switch gets the download from ISE and shows that it should use the URL redirect with the correct ACL.

From the client pc I can get name resolution for anything I ping. I also can ping the ise server by name. The ACL that is downloaded it as follows:

    50 permit tcp any any eq 443
    51 permit tcp any any eq 8443
    60 deny ip any any
The machine passes the Authentication with MAB and hits the CWA Authorization profile, ISE shows the cient as "Pending" then the next entry above that is the log is the dACL getting pushed to the switch. Could part of the issue be that the device shows Unknown for IP address? The command ip device tracking is in the swtich:
ISEtest3560#show running-config | include tracking
ip device tracking

We have 802.1x clients working and the IP address for those do show up..
Please advise,

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

Diffrence Between Local IE And Central IE

Hi All,
What is the difference between the local Integration Engine And the Central Integration Engine ???
Please Explain me
Regards
Vamsi

The systems on which SAP WAS is installed has Integration Engine as one of its components. Now for PI/XI also WAS is a must. Therefore PI/XI also has an Integration Engine called as Integration Server.
Now talking in terms of PI/XI, Integration Server has Adapter Engine, Integration engine (for pipeline steps) and Business Process Engine. This Integration Server is the central Integration Engine.
The Integration Engine of other systems is termed as local Integration Engine

Cisco Ise Central Web authentication not working

Hello Guys,
CWA is not working. It says that authentication suceeded but posture status is pending. No error in my Monitor--authentication. Checking it in my Windows 7, it does not shows the CWA portal.
What might be the possible problem of this.?
thanks
