Hi,
I am trying to load dynamic modules in snmp agent.
I am running snmp agent like:
sudo /home/vedams/netsnmp_build/sbin/snmpd -c
/home/vedams/netsnmp_build/share/snmp/snmpd.conf -DserialNumber
Below is log of /var/log/snmpd.log:
serialNumber: Initializing
serialNumber: Initializing
duplicate registration: MIB modules serialNumber and serialNumber (oid
.1.3.6.1.3.98.1.2.0).
NET-SNMP version 5.7.2.1
Why this "duplicate registration" is coming?
I have attached all files what i am using.
Regards
Nikesh
