[SNMP4J] snmp4j securityEngineID vs contextEngineID

[ulrich berl]

Hi!
 
During tests with snmp v3 i get little confused about contextEngineID and securityEngineID.
 
For sending snmp v3 request i use net-snmp tool snmpget:
 
There are two options available for specifying an engineId:
 
  -e ENGINE-ID          set security engine ID (e.g. 800000020109840301)
  -E ENGINE-ID          set context engine ID (e.g. 800000020109840301)


The snmpget request works without specifying an engineId - it will do a discovery first.
Specifying e or E or both of them with correct snmp4j-agent engineId will work too.

Specifying -e with wrong engineId will result in: 'Timeout: No Response from 127.0.0.1.'
Specifying -E with wrong engineId will result in: 'snmpget: Unknown Report message'

Actually if specifying -e or -E i have to use the same engineId ...

What about contextEngineID/securityEngineID in snmp4j ?
How can i configure different values for them ?
