When sending requests, can be left as the default value of a 0-length byte array in most cases. If the remote SNMP entity has not been contacted before, this will result in automatic discovery when the message is sent, and Manager.EngineCache will be updated with the discovered details. If the remote SNMP entity has been previously discovered, the EngineId will be automatically substituted from Manager.EngineCache.

If the correct value for the remote SNMP entity's EngineId is specified for the initial message, EngineId discovery will not occur.
