Help send traps snmpv3 to brocades

I am having a problem when it comes to being able to send traps by snmpv3, for v2 everything is going well for me but the problem I have with v3 is that when I create the user within librenms and I indicate the flag -e 0X00000 for example and when I go to the brocade cabin does not recognize the format of engineid 0X00000 and the brocades expect an engine id like 00:00:00 I try to create the user with 0X00000 in librenms but it does not work, can someone give me a solution on how to send traps without that engineid or how create an engineid style 0X00000
