Hi Fabrice,
Your suggestion makes sense, I will give it a shot tomorrow.
According to the Cisco documentation:
This example shows how to configure an 802.1x-enabled port to remove the
current session and initiate authentication with a new device when it connects
to the port:
Switch(config-if)# authentication violation replace
I will keep you posted.
Thank you,Vianney

Packetfence 6.1.0
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:
