The SNMP trap from a Nortel Switch and uses SNMPv1. This nortel Switch
can only be configured to send Traps SNMPv1.
I don't no, if it would work With SNMPv2. I only see, that the
Display-Hint is defined in a MIB-file called "SNMPv2-TC.txt.

With the output option -Ox, it is decoded well (from manual page snmpcmd):
-Ox Display string values as Hex strings (unless there is a
DISPLAY-HINT defined for the corresponding MIB object).
By default, the library attempts to determine whether the
value is a printable or binary string, and displays it accordingly.
This option does not affect objects that do have a Display Hint.
What algorithm uses snmptrapd to determine, whether it is a sting or
hex-string?
because of statement from man page : "By default, the library attempts
to determine whether the value is a printable or binary string, and
displays it accordingly."
Don't know, how to solve this problem ..
Thanks Meike
