Hi Guys,

I have configured SNMP v2c using
snmp-server enable traps snmp linkup
snmp-server host 10.1.1.2 version 2c cisco

the debuging show snmp v2 trap was sent (after shut/no shut of course).

When i tried snmp v3 using:
snmp-server enable traps snmp linkup
snmp-server host 10.1.1.2 version 3 USER
snmp-server group G1 version 3 priv
snmp-server USER G1 version 3 auth md5 cisco priv des cisco

the debuging show snmp v2 trap was sent as well .Although wireshark showed that snmp version is 3,
i used also management server that is ByteSphere , he showed traps received from v2c config , but didn't receive anything from version 3
Any Ideas ????

May be it is referring to SNMP v2u which is User Based Model.
