The Messenger type exposes the following members.

Properties

	Name	Description
	AuthenticationFailure	If the authentication module returns failure, then the message cannot be trusted, so the usmStatsWrongDigests counter is incremented and an error indication (authenticationFailure) together with the OID and value of the incremented counter is returned to the calling module.
	DecryptionError	If the privacy module returns failure, then the message can not be processed, so the usmStatsDecryptionErrors counter is incremented and an error indication (decryptionError) together with the OID and value of the incremented counter is returned to the calling module.
	MaxMessageSize	Max message size used in #SNMP.
	NextDiscovery	Obsolete. Returns a new discovery request.
	NextMessageId	Gets the message counter.
	NextRequestId	Gets the request counter.
	NotInTimeWindow	If the message is considered to be outside of the Time Window then the usmStatsNotInTimeWindows counter is incremented and an error indication (notInTimeWindow) together with the OID, the value of the incremented counter, and an indication that the error must be reported with a securityLevel of authNoPriv, is returned to the calling module
	UnknownEngineId	If the value of the msgAuthoritativeEngineID field in the securityParameters is unknown then the usmStatsUnknownEngineIDs counter is incremented, and an error indication (unknownEngineID) together with the OID and value of the incremented counter is returned to the calling module.
	UnknownSecurityName	Information about the value of the msgUserName and msgAuthoritativeEngineID fields is extracted from the Local Configuration Datastore (LCD, usmUserTable). If no information is available for the user, then the usmStatsUnknownUserNames counter is incremented and an error indication (unknownSecurityName) together with the OID and value of the incremented counter is returned to the calling module.
	UnsupportedSecurityLevel	If the information about the user indicates that it does not support the securityLevel requested by the caller, then the usmStatsUnsupportedSecLevels counter is incremented and an error indication (unsupportedSecurityLevel) together with the OID and value of the incremented counter is returned to the calling module.
	UseFullRange	A flag to control request ID range.
