and it actively maintained but this is without use of the SNMP V3. As far
as I know we (Ericsson) have never used the SNMP application with V3 in
products.  The SNMP V3 implementation has been available for +10 years but
since it is not or almost not used we have not actively maintained it
except the test cases we have which are not exhaustive.


Contributions with bugfixes and improvements in this area are are very
welcome.
