Paulo,
I don't see any security traps coming from the switch with the log you
sent. Make sure the device is NOT authorized on any other port of the
switch on the same VLAN of port 15. Otherwise, the switch will not send
SNMP traps.

Hello Everyone on the list ,
This is my first post , So im trying to authenticate (allow)
only the mac-addresses i have registered in packetfence
database i added then in NODES
Im dont use dynamic vlan assigment so its static vlans ,
basicly i work with class b adresses so i have 172.16 to
172.31 vlans and no guest vlan .
So i added a swich for testing in CONFIGURATION -> SWITCH , i
have configured the snmp comunity read key , and SNMP Trap
Community key as well . IP address 172.20.0.11
cisco 2960
....
.....

#snmp-server enables traps
#snmp-server host 172.20.0.190 1np@net_ro
172.20.0.190 is my PacketFence address .
This is the output of tcpdump -i eth0 host 172.20.0.11 (switch)
