[SNMP4J] How to Combine SNMP4J Agent and Dell OpenManage

[Frank Fock]

Hi Hong,

If you want to follow the second option (which I do not recommend - 
because it is not what the standard
suggests), you will have to implement one or more MOSubtreeProxy instances.
Alternatively, you can also use the SNMP4J-PROXY-MIB and configure it 
appropriately.

For the first option, simply add (register) the SnmpProxyMib 
implementation to your agent and
configure it as described in the RFC for the SNMP-PROXY-MIB.

Best regards,
Frank
