ISE wireless CPP with redirect exclusions, possible?

Hi all, a little bit of a tricky situation here. I've got a wireless network and ISE 1.1.1. The wireless is mixed 7.0 and 7.3 code.
On an ISE wired installation it's easy to have an authorization rule that URL redirects users to the client provisioning portal *BUT* to have a redirect ACL on the switch with deny statements that excludes specific websites from the redirection. This is done so users can click on remediation links from the NAC Agent and get to websites to download anti-virus, sig updates, windows updates, etc... but all other web attempts get redirected to the CPP.
All fine and it works perfectly on the wired network. HOWEVER, I can't seem to find a similar way to do this on the wireless network. While you can create a posture redirection policy to send them to the CPP with an ACL, that ACL seems to only permit or deny traffic per a standard ACL. Meaning a user gets on but any attempt to go anywhere in a browser redirects to the CPP. This makes it impossible to get to the remediation pages.
Is there any way to accomplish what I'm trying to do here? It seems like it should be a basic function.

Sorry I had some personal issues to deal with and just got a chance to follow up on this. Firs of all, good job on figuring it out and posting the findings back here! (+5) from me for that!
To answer your questions:
#1. You are 100% about the logic on the WLC ACLs vs Switch ACLs. On switches "deny" means "don't redirect" the traffic, thus permit it on the network. On the WLCs "deny" means "redirect" the traffic, hence don't allow it on the network. I am not sure why Cisco did this but different BUs, different teams, etc
#2. You are also correct on this one. Your vWLC and ISE are working as expected. While switches support dACLs, WLCs only support "named ACL." As a result, when referencing ACLs on ISE for wireless, that ACL has to exist on the WLC and it MUST BE NAMED THE SAME or it won't work.
Hope this helps. If you issues are resolved please mark the thread as "answered"

Wireless webauth with ISE

Hello,
I have a wlan in my controller with redirect feature in ise guest portal.
The question is, there some "feature" to disconnect the clients if the connection is idle by one hour or less?
If yes, this configuration is made in ISE ou in the Controller?
Another question, i need to block simultaneos login in ISE guest portal, its possible? I have ISE version 1.1.2.
Thanks.
Rafael

Well, they're timers for two different things. The Controller -> General is an idle/activity timer. When we don't "hear" any transmissions for this client for this length of time, we will deauthenticate regardless if there is still time remaining in the "Session timeout" configured in the WLAN/Advanced tab.
However, if the client is being heard, and the idle timeout is not expiring, the Session timer will cause the client to be deauthenticated when it expires. In that sense, the session timer is a hard stop timer in that it begins counting when the client hits the RUN state and when it counts down the session is over, regardless if they user is idle or not.
The idle timer counts down from last transmission received and when it expires the client deauthenticates regardless if the session timer has been reached.
So in a sense these don't "override" one another, but whichever is reached first will cause the deauthentication. Does that make sense?

Possible to use non-AT&T wireless card with iPad??

Thinking of getting an iPad, however I travel frequently and after looking at the outlandish prices for international data plans, I am about ready to give up on the idea. Anyone know if it is possible to use a non-AT&T wireless card with the iPad? I'm guessing there would be a compatibility issue of some sort.

The 3G iPad is not locked to a particular service provider. You can get a local Sim card and data plan in many countries. This article will give you some idea of what's available: http://gigaom.com/2010/05/10/ipad-data-plan-guide/

I want to use my jetpack 890L as a wireless router to allow wireless printing with a canon laser printer. Is this possible, and does the jetpack support WPS?

I want to use my jetpack 890L as a wireless router to enable wireless printing with a canon laser printer. Is this possible, and does the jetpack support WPS?

I’ve used several wireless printers with a 4510 and 5510 Jetpack and they all print just fine. The MHS890L does not support WPS. The WPS Wikipedia article briefly addresses the reason why you should not use WPS. If you’re having trouble setting up your printer the manufacturer has a toll free support line to help you. Your Jetpack has the Wi-Fi Password on the bottom, under the battery, and or in the LED display.

How do I view the list of wireless routers my ipad has successfully authenticated with, and if possible when the last connection to each was made?

How do I view the list of wireless routers my ipad has successfully authenticated with, and if possible when the last connection to each was made?

The information is of course stored on the device, but currently thee is no way to get to it. It is unknown whether iOS stores the date info for each connection.
As to whether a program can be written, its likely it can, but unlikely it can be done by anyone other than Apple, as by design, 3rd party Apps are not allowed to core system functions like that so its unlikely any App could list your connection history.
As has been said to remove a single connection from the iPad you need to be in range of it, tap the circle on the right side of the router name, and then tap on Forget this network.

Possible bug using go tag with redirection under SSL?

I've been testing an application under SSL and have noticed that some links "pop-out of SSL". Upon further inspection I noticed the links were using <go> tags with redirect set to true.
Does anyone know where <go> gets the URL it uses? I'm wondering if this might be a webcache configuration issue or appserver config issue.
note: using AS 10g 9.0.4.1.1
Thanks in advance!
/SFL

Hi all,
Just thought I'd update on resolution. As suspected, an AS config issue was responsible for this glitch. Long story short WebCache can communicate in 2 ways w/ an origin server (HTTP or HTTPS). You can have WebCache use SSL w/ the client and still communicate with the origin server using HTTP (which was our case). PITFALL: the origin server is unaware of the use of SSL by the client (WebCache only "knows"). SINCE THE ORIGIN SERVER IS THE ONE EXECUTING THE <GO> TAG, when using redirect=true attribute with the tag, the URL generated by the rewrite routine is HTTP and not HTTPS as one might expect when accessing the app via SSL.
Hope I can spare someone else the headache...
Cheers!

Creating a seamless wireless network with 2 AExpress units

I have 2 Airport Express units in different parts of my house. I have struggled for YEARS trying to get them to create one seamless wireless network with the same name that I could float between. I have never been able to get that to work. anyone?
I know that some of the problems MAY have to do with the non-apple router settings, but I just have never gotten a clear response form anyone about weather it is doable, and/or worth doing. I would settle for 2 seperate wireless networks that didn't compete with each other and/or constantly need re-booting to stay active. I am generally the most tech savvy person I know and am consulted on IT by friends and colleageus regularly, but I just cannot figure this one out..
I am totally capable of setting this up, both in the router and the AE units, if someone can just tell me that;
1) yes it is possible and it will work, and
2) just set it up like this...

Thanks for the clarification. Check your AirPort Express devices one at a time, but other than different device names to avoid confusion.....AirPort Express 1, AirPort Express 2....for example, the settings should look this:
Open AirPort Utility , select one AirPort Express, click Manual Setup
Click the Wireless tab below th row of icons
Wireless Mode = Create a wireless network
Wireless Network Name = Your choice
No check mark needed next to "Allow this network to be extended"
Radio Mode = 802.11n (802.11 b/g compatible) a good choice, but you can choose other combinations by holding down the option key on your Mac while you click on the selection box
Channel = Automatic
Wireless Security = WPA2 Personal an excellent choice if all of your devices are compatible with this setting
Wireless Password = Your wireless password
Confirm Password
Click the Internet icon
Connect Using = Ethernet
Connection Sharing = Off (Bridge Mode)
Update to save settings
Configure AirPort Express 2 exactly the same way and Update to save settings
Then, power down the entire network.....all devices....order is not important
Wait a moment, then start the modem/router first and let it run 2-3 minutes by itself
Start each AirPort Express the same way
Start each other network device one at a time about a minute apart
Check for proper network operation
IF....you did not have your AirPort Express devices in Bridge Mode before.....that is the reason why you are having issues now and also is the reason why the "roaming" network was not working.....assuming that there was a reasonable overlap in wireless coverage between the 2 Express devices, of course.
If you want to try the "roaming" setup again, assign the exact same wireless network name, security and password to both Express devices and confirm again that both are setup in Bridge Mode as the very last step before you click the Update button in AirPort Utility.
Power down the entire network and start up in sequence as well as in the example above.

ISE 1.2 With WLC and AD

Hi everyone,
What is the steps and Procedure implement Wired and wireless authentication with ISE, WLC and AD for a LAB environment. currently the following are done.
The wireless network is configured with 2 SSID (Staff and Guest)
Active Directory, DNS, DHCP, and NTP configured & synced.
ISE and AD running on C220 VMs, and WLC is 5760 Appliance.
Please provide your thoughts and assistance.
Regards

You have to implement dot1x and radius between your NAD and ISE device.
Using the switch 3850, that are the steps:

aaa new-model
aaa authentication login default local
aaa authentication dot1x default group radius
aaa authorization network default group radius
aaa authorization auth-proxy default group radius
aaa accounting update periodic 5

aaa accounting dot1x default start-stop group radius
!this password will be used to communicate with ISE and to verify reachability
!between ISE and Switch

enable dot1X on windows machine, or using cisco NAM.
you can enable debugging on aaa authentication to see the events.
you have to create this user on ISE (RADIUS-HEALTH).
3850#test aaa group radius username password new-code
and observe the result. You are supposed to have user authenticated successfully.
You Must also have define these device in ISE on the radius interface.
ip radius source-interface ..... use this interface ip address to define Ip address of the NAD device in ISE.
administration-->network resources -->Network Devices-->Add
input the name
input the Ip address for radius communication
select the authentication settings and field the corresponding shared secret radius key
select snmp settings and select version 2c.
snmp community : ciscoro
you can customize the polling interval if you want and that all.
you are supposed to received message communication between your NAD and ISE.
After you can do the procedure for WLC device.
I will fill it after you have passed the first steps (3850 authentication).

ISE 1.2 with MDM intergration

Hi, I'm trying to intergrate with Zen MDM.
has anyone seen this issue ?
there is no mdm policy to configure in ISE, as I know, but it keeps me to redirect to that page.
I already added MDM server in administration -> network resources -> MDM
and when I ping and nslookup, i can successfully ping and lookup the ip address of mdm.
Thank you.

jiyoung,
There are ACLs to be created on the WLC, Authorization Policies and Profiles on the ISE.
For a good understanding of what needs to be done to get this fully configured, go here:
http://wikicentral.cisco.com/display/VTANDGOLD/ISE+1.2
and choose the GOLDlab: ISE 1.2 - BYOD-MDM Lab on the right side for Partner Education.
If you cannot log in, your Account Manager can get you access. This is a really thorough walk-through of configuring the ISE to connect with a third-party MDM server and it lets you do all the configuration.

Connecting to Wireless AP with non-english SSID name

Hi everyone
I have a wireless AP with a non-english name ( The name is "IsolÈ coffee"), when I do scan for wireless network in Mac OS X it will not show this network and even if I use iStumbler it will show it but it will not able to connect to it
if I use any Windows PC/Linux it can connect to the wireless AP with no issue
is it possible in anyway to connect to this wireless AP (and NO I can't change the SSID name because I don't own it, it's a public AP)
Thanks

This post is a little old, i don't know if it's proper to add a reply. I just got the same problem here, and hope someone would work on it. The ssid is some chinese characters, and i don't have authority to change it. Same as what AhmadT mentionded, airport couldn't find anything, even if the ssid is typed in manually, it doesn't work.
The only workaround i could find is to use the other wifi card (USB ones), and have it driven in WindowsXp which is running in VMWARE Fusion. so that i could access the wifi-router and internet in the vm-machine.

Wireless headset with FM Radio

Is it possible to use the wireless headset with the FM radio. It wants me to insert the audio plug to turn on the radio.

I've used the bluetooth transmitter that comes with the Plantronics BackBeat 906 headset. I just plug it into the 3.5 mm jack, pair with phone then start the FM application. Works great for me on a Droid x.

Select lists empty or POPup LOV needed with redirect

Hi all,
I have a form where i need 6 select lists with redirect or 6 POPup LOV with redirects.
These select lists are separated in three groups
like this
group 1
departments select list with redirect
employees popup lov (query based on the value of department)
group2
Order select list with redirect
OrderItem popup lov but needs a redirect here for employees (query based on the value of countries)
employees popup lov (query based on the value of department)
group 3
some status select list with redirect
When I choose the first select list the popup LOV is populated with good values
when i select a value from the second select list the value in the first list disappears, including the value of the first popup lov. etc.
How is it possible to keep the values stored in the first selects list when selecting some value of the second list.
How is is possible to make a popup lov with redirect so that the values are in session
and can be used in another popup lov?
Is someone there who have experiences with this issue?
thanks in advance,
Hugo

Hi Hugo,
I don't think that you need a redirect for that. Check out my AJAX cascading popup lov solution.

Does Cisco ISE-3315-K9 with ise version: Service Engine: 1.0.4.573 support command accouting like ACS

Hi
Can Anybody can update whether ISE-3315-K9 with ise version: Service Engine: 1.0.4.573 , supports the command level accounting
Bascially , we have integrated Cisco Switches with Cisco ISE for Device Authentication using Radius , we are able get the authentication logs on to the devices , but for any command changes or update done on Cisco devices we are not able to get the command accounting ..
has succeed in command level accounting on Cisco ISE ..
Please update
Cisco ISE doesn't have TACACS feature ...

Command Accounting is a TACACS+ feature so not for ISE....yet.
However, you can do the following to send commands to syslog and not including passwords (hidekeys). I just picked 200 commands/lines to store in the local command buffer/log. increase or decrease as you have memory. The notify syslog is what sends it via syslog.
conf t
archive
log config
logging enable
logging size 200
hidekeys
notify syslog
end
wr mem
Remember, syslog is clear text :-) log away from user traffic when possible. Or use TLS based syslog when possible.
I hope you find this answer useful, if it was satisfactory for you, please mark the question as Answered.

[WLC - CWA] [ISE] Wlan Portal with Local Switiching

Description: Guest Portal ISE (WLAN) in a Flexconnect local switching enviorment.
Problem: The communication stops everytime we turn on the feature Radius NAC on the WLC.
We are trying to use Central WebAuth in a Flexconnect environment and with so the procedure that we are using it´s the one that´s available in the cisco DOCS ( http://www.cisco.com/c/en/us/support/docs/security/identity-services-engine/116087-configure-cwa-wlc-ise-00.html ) but there´s something occuring in my setup. I´ve configured step by step the WLC and ISE in accordance with previous DOC but I can´t establish communication everytime I turn on the feature RADIUS NAC in the WLC.
All the ACL´s were configured, I can see the ISE policy beeing sent to the client but when the PC tries to establish the connection to him nothing leaves the PC ( a simple ping was done ). I´ve tried a bunch of setups to see if it was a misconfiguration or something else but at the end , everytime I trun on the NAC feature the final client looses all the comms to anywere.
You can see in the following attachment the setup of WLC, and AP with flexconnect groups (I´ve also tried without a group but the final result was the same)
We are using a WLC 5500 with 7.6.120.0 ( http://www.cisco.com/c/en/us/td/docs/wireless/controller/7-6/configuration-guide/b_cg76.html ) and the only thing I can foun is a simple note stating,
"Flex local switching with Radius NAC support is added in Release 7.2.110.0. It is not supported in 7.0 Releases and 7.2 Releases. Downgrading 7.2.110.0 and later releases to either 7.2 or 7.0 releases will require you to reconfigure the WLAN for Radius NAC feature to work."
In the Flexconnect Feature Matrix the RADIUS NAC is supported in a local switching enviorment ( http://www.cisco.com/c/en/us/support/docs/wireless/5500-series-wireless-controllers/112042-technote-product-00.html?referring_site=RE&pos=3&page=http://www.cisco.com/c/en/us/support/docs/wireless/flex-7500-series-wireless-controllers/113605-ewa-flex-guide-00.html) but what we´ve found out so far it´s the other way around.
Another thing that we´ve found is that in the version 7.4 configuration guide ( http://www.cisco.com/c/en/us/td/docs/wireless/controller/7-4/configuration/guides/consolidated/b_cg74_CONSOLIDATED/b_cg74_CONSOLIDATED_chapter_0110100.html#ID2372 ) cisco says that the "FlexConnect local switching is not supported."
So, after seeing several docs my question is: Does Cisco support Radius NAC in a local switching environment ?

Viten,
tnx for the quick reply but,
a) what do you mean by webauth ( http://www.cisco.com/c/en/us/support/docs/security/identity-services-engine/116087-configure-cwa-wlc-ise-00.html) ?
b) When I say comms stop is that I´m simple using ping as a test to see what happens in the client.Whenever I activate the radius feature the final client (laptop) ceases all comms in a local switching environment.

DS
