802.1x port security auth for MX &SX endpoints registered on CUCM

I'm trying to configure 802.1x on MX and SX type endpoints registered on CUCM v10.5.

From CUCM I pushed the LSC and on the endpoint: Security > CUCM I see:

CUCM status
CUCM is enabled.
CTL status
CTL is installed.
ITL status
ITL is installed.
LSC status
Certificates are installed.
Operation status
No pending operations.

IEEE802.1x config done on endpoint (see attached screenshot).

I've also added the CA certificates on the endpoint.

But when the switch port is activated for 802.1x the endpoint is not reachable anymore and authentication failed is showed on the switch logs.

Did somebody already managed to make this work?

For IP-phones there's a 802.1x setting on the CUCM but for TP endpoints this is not the case.

As follow-up of my own thread here some hints to make it work:

- The codec series do not use the same identity format as for IP phones in their certificate. They use 'SEP' + mac-address instead. So the ISE server needs to have a rule that matches on this name combination.

- the LSC of the UCM must be installed on the Codec: use "Install/Upgrade by Authentication string"

- the LSC certificate must be enabled for 802.1X

- on the codec the following fields are needed:

- Identity: 'SEP' + mac-address

- Mode: On

- TlsVerify: Off

- UseClientCertificate: On

- EAP MD5: Off

- PEAP: Off

- TLS: On

- Ttls: Off

- On the switch:

Radius-server vsa send authentication

Radius-server vsa send accounting

- On the switch port (note: the voice VLAN must be used):

interface GigabitEthernet2/0/46
