Hi Luca,
You can use the "Tools/Decode As..." to force Ethereal to decode a UDP message as an SNMP-message.
Just mark a frame that you want to decode as SNMP and select "Decode As..." from the Tools menu.
You can then select that all UDP-messages sent to or from those UDP ports should be decoded as SNMP by selecting "source (xxx) port", "destination (yyy) port" or "both".
