Which trap receiver are you using? snmptrapd, or something else?

I tried the command:

snmptrap -v 3 -u  Simon  -a MD5 -A  SimonPass -l authNoPriv 172.27.37.227 "" coldStart.0

(with security name  : Simon and  authentication password  : SimonPass ).

These parameters are not set in any config files anywhere.

On another PC with IP 172.27.37.227, I have a MIB browser and trap receiver. The trap receiver is receiving the trap even when it is not configured with the security name  : Simon and  authentication password  : SimonPass .

I was not expecting to receive the trap until I configured the trap receiver with the same security name and authentication password!?!

        I do receive the trap on my Trap Receiver even if I didn't
        specify a Username and Authentication password in the MIB
        browser (on 172.27.37.227 ) !

    Do you mean the security name instead of the username?
    The -u sets the security name, -A sets the authentication
    password. They're set in the example you gave.

    Or are you saying that you tried that command without the username
    and authentication password?
    If so, are you sure that you don't have those parameters set in an
    snmp configuration file?

    Trying the command with -Dread_config:line may help here.

    I tried snmptrap 5.9.3 with no -u and -A flags and with/without a
    configuration file and it only worked with the configuration file.
