The most likely reason is because of a mismatch in the vendor ID, which is why I'd asked you to share the XML.

Thanks for all the replies!
As it turns out, for some as-yet unknown reason, removing the custom profile I created and using the [Cisco - Reauthenticate-Session] profile instead allows it to work. I don't understand it, but I'll take the win and hope for clearer understanding in the future.

I have an enforcement profile that is supposed to send a RFC3576 Disconnect-Request:

The Access Tracker shows that it processed the profile and generated the request:

And the Access Tracker log shows no problems generating the message and shows this:
2025-09-18 08:09:28,348 [RequestHandler-1-0x7ff6453e9700 h=345 c=W00000001-01-68cbf677] DEBUG Core.PETaskRadiusCoAEnfProfileBuilder - sendRadiusCoAResponse: Sending CoAEnfRequest={"content":{"cnc_actions":{"display_name":"Terminate Session - Custom","id":1,"name":"Meraki-Terminate-Session","params":{"name":"Calling-Station-Id","value":"B8-31-B5-87-2D-2D"},{"name":"Acct-Session-Id","value":"09CC655335FEE694"},{"name":"Event-Timestamp","value":"1758197368"},{"name":"NAS-IP-Address","value":"10.28.128.209"}],"type":"RADIUS"}],"mac_address":"b831b5872d2d"},"id":"R00000000-01-68cbf653","name":"cnc_request"}

But a packet trace on ClearPass shows no evidence that the CoA-Disconnect message was sent.
Has anyone else seen this issue and found a solution?
I found similar issues in other forum posts, but no solution was mentioned.
Is there a low-level log on CPPM that might indicate why it didn't send the packet after building it?
Thanks in advance for any advice.
