Re: How can I define my own trap?

Hello,

I finally solved my problem! I would like to thank everybody of this mailing
list for the quick and useful answers provided. They really helped me to
understand all the snmp traps stuff.

I only have one last simple question. One of the attributes that I extract
from the database (the time) has the following format:* "19:55:57"**.* I
defined it as STRING on my MIB tree but when I execute snmptrap command, it
complains:

*Time: Bad variable type (Type of attribute is INTEGER, not OCTET STRING)*

Do you have any idea of what format should I use?

Thanks again.
