Hello everyone,
i am currently deploying cisco ISE and already facing a few problems. The cisco ise and authenticator switch are in the same VLAN but somehow i cant see the switch on the ISE GUI. Same with the connected endpoints on the switch. I´m using the cisco catalyst 2960-X with the Cisco IOS 15.2.2E8bin. I will attach some screenshots of my switch config for the communication with the ISE server. I even can´t see anly logs if i go to the live section on the GUI. Could one reason be that i haven´t configured a dns name yet for the ise server or is that not necessary? I hope someone can help me out, its getting fairly frustrating.
PS:
I also cant get rid of the "authentication open" config on the switch ports. I once enabled them but couldnt find a command that deactivates it.
Solved! Go to Solution.

@CasualUser01 right but that doesn't confirm whether you've enabled 802.1X globally using that command I provided.
If you copied and pasted those commands above, then you probably haven't enabled 802.1X globally.

Oh yea, i think that i just enabled it for the 12 port range that i defined. I didn´t need all the 24ports, do you think it would make a difference if i enable dot1x globally? Because it should be a very easy configuration for the device to show up in the ise gui, but somehow it doesnt work. I used a 2960-S switch before that and i couldn´t implement it either.

@CasualUser01 it's not optional, it's a requirement - so yes it will make a difference.
You must enable 802.1X globally, not just under the interface.
This section is from the guide I previously supplied.
Enable 802.1X globally on the switch,use the dot1x system-auth-controlcommand in global configuration mode.
c9300-Sw(config)#dot1x system-auth-control

Oh ok my bad, when im at office again i will enable it globally and then look again if it solves the problem. Thank you for taking time to help me out, hopefully it will work.

Oh i actually looked into the 2960-S switch config which i had configured before the 2960-X and there i used the command dot1x system-auth-control, but it was also not visible in the gui. I think there is something else which i have not discovered yet why it does not work.

Hi Rob,
i enabled dot1x globally and then restarted the ise-services. The device still does not show up and authentications are not being sent to the ise server. If i do show aaa servers i get this:
SWCGN1ACST006#sh aaa servers

And here is also the sh authentication sessions command on the switch:
SWCGN1ACST006#sh authentication sessions
Interface MAC Address Method Domain Status Fg Session ID
Gi1/0/3 c018.0359.7f45 N/A UNKNOWN Unauth 0A0116060000002408D54615
Session count = 1
Key to Session Events Blocked Status Flags:
A - Applying Policy (multi-line status for details)
D - Awaiting Deletion
F - Final Removal in progress
I - Awaiting IIF ID allocation
N - Waiting for AAA to come up
P - Pushed Session
R - Removing User Profile (multi-line status for details)
U - Applying User Profile (multi-line status for details)
X - Unknown Blocker
However now i get the message that dot1x auth fails but it does not authorize the critical vlan
Apr 11 06:55:38.316: %DOT1X-5-FAIL: Authentication failed for client (c018.0359.7f45) on Interface Gi1/0/3 AuditSessionID 0A0116060000002408D54615
