Bad operator (INTEGER): At line 73 in /usr/share/snmp/mibs/ietf/SNMPv2-PDU when using "service snmptrapd status"

 PROBLEM:

when I tried to load one of the SPG8000A mib to ubuntu SNMP, the net-snmp library just will not parse the mib file to the OID.

as I troubleshoot I found out  

root@user-x8sti:~# service snmptrapd restart                                                                                                 

root@user-x8sti:~# service snmptrapd status

Solution:

To fix the error: copy or make a new SNMPv2PDU file in the

/usr/share/mibs/ietf/ directory with the below MIB information

or you can run this command in the linux commandline. 

wget http://pastebin.com/raw.php?i=p3QyuXzZ -O /usr/share/mibs/ietf/SNMPv2-PDU

 Remember to run service snmptrapd restart
this should fix the OID to mib information.
