Hi:

I am attempting to follow the Cisco TrustSec Deployment guide (http://www.cisco.com/c/dam/en/us/td/docs/solutions/Enterprise/Security/TrustSec_2-0/trustsec_2-0_dig.pdf).

So far things have been going well. I am at the point of adding in my Seed device. After completing the setup on ISE and then the switch itself (a Cisco Catalyst 3650) I am note that the environment data doesn't appear to have been download. However the PAC file is successfully generated.

CTS Environment Data

====================

Current state = START

Last status = Failed

Environment data is empty

State Machine is running

Retry_timer (60 secs) is running

As you can see it says Last status = Failed.

Enabling debug logging for cts outputs the following

Within ISE itself it shows a successful authentication and PAC generation. However the log messages there are as follows. Not sure if it is significant that it says Access-Reject status at the end.

It helped me.

In my case:

aaa authorization network ISE-GROUP group ISE-GROUP 
cts authorization list ISE-GROUP
radius server ISE

Hi Mattew,

I'm trying to integrate TrustSec as well, using Cisco ISE, on 3560 switch as a seed device. I'm getting the exact same symptoms as you do - the ISE reports that the switch has successfully authenticated, but no environmental data has been downloaded.

I followed this guide for configuring the ISE and the switch.

Have you been able to resolve this issue?

Thank you very much.

tony.parker · ‎09-21-2015

I also have the same issue.

Has anyone found a solution yet?

Thanks

Ryan Wolfe · ‎12-03-2015

Check out my reply above and see if that helps.

khorheesoo · ‎06-12-2016

Hi, my AAA Authorization network command is correct. Yet the problem persist. Anyone found any solution for this?

Appreciate if anyone could shed some light here.

Thanks

Hi,

I was just reading this and wondering what the result is if you run a "cts refresh environmental-data"? Does it pull down the data as expected?

Rafael Trujilho · ‎02-25-2018

Hi Community,

I have a CTS deployment with:

- ISE v2.0.1_p4

- Cisco switches 3850 (classification (dynamic - AuthZ from ISE) / propagation (SXP) / enforcement)

- Cisco switches 6500 - Sup2T (classification (static - IP-to-SGT) / propagation (SXP) / enforcement)

Currently the deployment passed to presents the problem on the environment-data download, from 3850 and 6K switches, where the status showing:

!

CTS Environment Data

====================

Current state = WAITING_RESPONSE

Last status = Timeout waiting for response

Environment data is empty

State Machine is running

Retry_timer (60 secs) is not running

!

The symptom appear to be from ISE side... In some cases 3850 and 6500 switches I don't have the same problem on environment-data. The refresh <cts refresh environment-data> is working.

Let me know if this symptom is experienced by other colleagues? Please.

Ryan Wolfe · ‎12-03-2015

Can you post the output of "show run aaa"? I was having the same issue and it was the syntax of the "aaa authorization network" statement. I was incorrectly specifying the method list.

It should look like this:

aaa authorization network [radius-server-group] group radius

I had it like this before and it wasn't working:

aaa authorization network cts group [radius-server-group]

Good luck,

Ryan

bakurenko · ‎09-14-2018

It helped me.

In my case:

aaa group server radius ISE-GROUP
 server name ISE
aaa authorization network ISE-GROUP group ISE-GROUP 
cts authorization list ISE-GROUP
radius server ISE
 address ipv4 x.x.x.x auth-port 1645 acct-port 1646
 pac key xxxxxxxx

Thanks,

This works for me as well - switch refreshed okay.

What I did then -

no aaa authorization network ISE-GROUP group ISE-GROUP

Now I enter what was 100% non-working before:

aaa authorization network ISE group ISE-GROUP

cts auth list ISE

crs refresh env

and I see it works. Miracle.

Heriberto Diaz · ‎11-27-2019

Hi

This solutions works for me DNAC with ISE, just change the ports

auth-port 1812 acct-port 1813 for auth-port 1645 acct-port 1646

Regards.

CCNASithk · ‎09-25-2017

my problem was I forgot the
cts authorization list <auth-list>
there was an aaa radius list to use, but I never told it to use it.
