Identity Services Engine (ISE) - Guest and Posture Troubleshooting
(Live Webcast Tuesday August 30th, 2016 at 10 am Pacific/ 1 pm Eastern)

Cisco ISE manages role-based security policy. It simplifies network-access delivery across wired, wireless, and VPN connections. ISE then integrates, consolidates, and automates the sharing of user and device data with other Cisco security and technology partners. This dynamic network access control improves IT operations as well as stopping and containing threats. As the modern network expands, the complexity of marshaling resources, managing disparate security solutions, and controlling risk grows as well. The potential impact of failing to identify and remediate security threats becomes very large indeed.
A different approach is required for both the management and the security of the evolving mobile enterprise. With superior user and device visibility, Cisco ISE delivers simplified mobility experiences to enterprises. It also shares vital contextual data with integrated technology partner solutions. The identification, containment, and remediation of threats are all accelerated through the integration, consolidation, and automation that Cisco ISE provides.  

This session provides an overview of: Guest and Posture Flow Troubleshooting We’re expecting a basic knowledge being the initial configuration for ISE redirect flows for Guest and Posture. If you want to review these setups, we recommend checking out these links.

Hi Guys,

We are implementing BYOD with ISE. We all know the android phones need to download cisco network assistant to playstore for it to work. And during native supplicant provisioning, wlc should only allow access to playstore. We have DNS ACL allowing access to and is working fine. But when actually downloading the app(cisco network assistant) it is being blocked. Checking in websense, playstore uses another url to download the app(websense sees as https://x.x.x.x). Websense is unable to get the url since it is https. Do you know what url playstore uses to download the app?

Hello Herbert,

Please ask your question in the Ask the Expert event.  Sam and Maciej will be able to answer your question there.

Best regards,



Hi my name is Ivan, I have a question

Is possible the Cisco ISE works like a dhcp server in a vpn conection, and reservate its ip address?

How can I do it



Cisco Employee

it can vary per android version as far as i know.

do a packet capture inside you will see:

1. "server name indicator extension" in the ssl client hello message

2. check in the capture for the DNS queries form the endpoint.

In ISE 2.1 the DHCP and DNS server capability was added, the reason behind it is to integrate with third part products that are not able to perform redirection by themselves.

I would not recommend using this design for any other purpose and i do not think this will work as we relay in this flow on vlan change which is not the case on the VPN connection.


Hi my name is Fernando, I have a question:

I have a Cisco (C3750E-universalk9-M), which supports a solution of a client and for 4 days I have this error% SSH-3-BAD_PACK_LEN: Bad packet length. Can you help me solve this issue?

Many thanks!


Hi Herbert,

Do you have a chance to look at this URL: It has the most common domain names used



these are the urls that works in my region.

To get the urls playstore is calling, you will have to add "." (without qoutation) on the allowed url in WLC, it will make wlc dns snoop all urls being called. Then debug the client, then on the client download the application. On WLC console, it will show on the url being called.
Below is the url for network setup assistant in my region.

Hi Vidhi,

I had an issue of mac spoofing logged with tac sometime ago and I was referred to this link  which shows this is a known bug.

Has this issue been addressed in any of latest ISE releases?
