Also what is the output on the switch ? (term mon).

...also moving a registered PC to another port will not work either.

Hi Fabrice,
It worked wonders by adding the suggested commands on my Cisco switch, I was
able to register new computers on that phone switch port without issues (no
more phone shutting down).
The new scenario I tested: connect another phone on the switch port where a
phone was registered before. In this case the new Cisco SPA phone will not
fishing loading, it shows on its display: "Initializing Network"
I tried disabling and enabling the switch port without success, I noticed the
switch port did not show any errors. Also I tried to pre-register the new
phones' mac addresses, but that did not help either.
Please advise.
Thank you,
Vianney

Hi Vianney,
i am sure it will work, also you can add " authentication mac-move permit" in
global configuration.

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

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:
