Resolution:-

#vi /etc/snmp/snmpd.conf

# Make at least snmpwalk -v 1 localhost -c public system fast again.
# name incl/excl subtree mask(optional)
view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.25.1.1

Note:- see the third line .. just add the MIB

After that restart the snmpd services.

#service snmpd restart

Now check
