IOS Device-Sensor and ISE profiling not working

Question

Hello,
I configured IOS device-sensor on one 2960CG-8-TCL switch. IOS is 15.2(2)E.
Switchconfig:
device-sensor filter-list dhcp list dhcp-list
 option name host-name
device-sensor filter-spec dhcp include list dhcp-list
device-sensor accounting
device-sensor notify all-changes
Switch does DHCP-Snooping and "show device-sensor cache all" shows the DHCP name:
Device: b2b5.2fff.sa43 on port GigabitEthernet0/1
Proto Type:Name                       Len Value
DHCP    12:host-name                   17 0C 0F 11 31 22 41 50 43 33 31 32 30 30 30 37 38
                                          38
RADIUS probe on ISE is activated and TCPdump shows the accounting packets from the switch (see attachment).
I configured a profiling rule ot check for DHCP-Hostname with "contains". This rule does not work however. The device is getting profiled with a MAC-OUI via RADIUS-probe but the DHCP-Profile is not working.
Is this supposed to work?

Answer 1

That is interesting. I haven't worked with the "Device Sensor" much so I am running out of ideas. I really thought the certainty level was going to fix your issue as I have had issues similar like yours in the past where the certainty level of my custom rule was the same as a default one so mine custom rule was never hit. . I thought this was the case with you since your device was hitting the parent policy of "HP-Device" but not moving any further. With that being  l would still recommend keeping your custom conditions with higher certainty levels to avoid such situations.
Couple of more things:
1. What profiling probes do you have enabled?
2. Have you tried retrieving the DHCP hostname via another sensor/method. For example, via the DHCP probe and ip-helper?
3. Do you have the following commands entered on your switch:
access-session template monitor
no macro auto monitor
device-sensor accounting
device-sensor notify all-changes
