Hi Vianney,
the issue is on the switch side, not in packetfence side.
Add that to your switch port config: authentication violation replace

Hi guys,
I just added a Cisco Catalyst 2960-S (running latest IOS version) to
my test environment using 802.1X with MAC Authentication bypass
(MultiDomain) following the Packetfence official documentation.
I hooked up a Voice-IP phone (Cisco SPA514) on one a switch port, the
phone was successfully registered on my voice VLAN, then I hooked up a
PC on the phone's switch port, went thru the registration process and
got it successfully registered on my production VLAN.
Everything was working as expected, until I decided to connect another
PC (never registered before) to the phone's switch port....the phone
went completely off, then I checked the switch port status, here is
the result:
GigabitEthernet1/0/37 is down, line protocol is down (err-disabled)
Port Name Status Vlan Duplex Speed Type
Gi1/0/37 err-disabled 162 auto auto
10/100/1000BaseTX
I re-plugged the phone to the switch port, but it did not help at all,
then I ran "shutdown" on the interface and then "no shutdown", then
everything when back to normal and I was able to register this new PC.
I was able to reproduce this issue twice.
I tested with both de-auth methods: SNMP and RADIUS.
Anything showed up on the packetfence.log
Here is my switch config on the device and Packetfence:
