ISE not recieving DHCP attributes from device sensor radius probe

duncanmj · ‎07-04-2019

Hi,

Anyone able to help with an issue i am having?

Issue with 3650 running 16.6.6 and ISE 2.6 (P1).

The device sensor seems to be working correctly as i can see CDP and DHCP attributes under "sh device-sesor cache all" however when looking under multiple devices in ISE context visibility i am only seeing the CDP attribues and not the DHCP attributes.

Switch Config:

aaa authentication login default group groupt local-case
aaa authentication enable default group groupt enable
aaa authentication dot1x default group groupr
aaa authorization console
aaa authorization exec default group groupt local if-authenticated
aaa authorization commands 15 default group groupt local if-authenticated
aaa authorization network default group groupr
aaa accounting send stop-record authentication failure
aaa accounting update newinfo periodic 240
aaa accounting identity default start-stop group groupr
aaa accounting exec default start-stop group groupt
aaa accounting commands 15 default start-stop group groupt
aaa accounting system default start-stop group groupt

Your configuration is looking OK from what I can tell. If possible, I would suggest to try IOS-XE 16.9.x pr 16.8.x train. If needed, engage Cisco TAC to troubleshoot.

I saw a similar issue a couple of months ago with 3650 on IOS-XE 16.6 (or 16.4?) train and ISE 2.4 (Patch 6 or 7?) but did not have time to dig deeper at the time. IIRC... the RADIUS account packets were not there in ISE profiler.log with profiler in DEBUG, so it's possible some data format problem.

Today I just tested two different combinations and both worked fine:

ISE 2.4 Patch 9 and IOS-XE 16.8.1s on 9300 with IBNS 2.0 configurations automated by DNA Center 1.2.6
ISE 2.6 Patch 1 and IOS-XE 3.6.3E on 3650 with IBNS 1.0 (manually configured)

Below captured by TCPDUMP of a RADIUS accounting request with the DHCP sensor data of a Windows 10 client from the 9300 edge switch to ISE in our lab:
