Constructor

Copy constructor. Initialize the class with the values of the parameter class values.

Prepare class for authNoPriv operations. Set privacy protocol to none

Prepare class for authPriv operations.

Build cached authentication and privacy encryption keys if they are appropriate for the selected security mode.

Clone current object

Determines whether the specified Object is equal to the current Object.

Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.

Calculates and returns current agents engine time. ValidateEngineTime()()()() is called prior to calculation to make sure current engine time is timely enough to use. EngineTime is calculated as last received engine time + difference in seconds between the time stamp saved when last time value was received and current time (using the internal GMT clock).

Serves as a hash function for a particular type.

Gets the Type of the current instance.

InitializePacket SNMP packet with values from this class. Works only on SNMP version 3 packets.

Creates a shallow copy of the current Object.

Prepare class for noAuthNoPriv operations. Set authentication and privacy protocols to none.

Reset the class. Initialize all member values to class defaults.

Reset privacy and authentication keys to null.

Returns a String that represents the current Object.

Update class values with SNMP version 3 discovery values from the supplied SnmpV3Packet class. Values updated are EngineId, EngineTime and EngineBoots.

Updates engine time timestamp. This value is used to determine if agents engine time stored in this class is valid. Timestamp is saved as DateTime class by default initialized to DateTime.MinValue. Timestamp value is stored in GMT to make it portable (if it is saved on one computer and loaded on another that uses a different time zone).

Copy all relevant values from the SnmpV3Packet class. Do not use this class for updating the SNMP version 3 discovery process results because secret name, authentication and privacy values are updated as well which discovery process doesn't use.

Checks validity of the class.

Validate agents engine time. Valid engine time value is time that has been initialized to a value other then default (DateTime.MinValue is default set in the constructor) and that has been updated in the last 10 times the SNMP v3 timely window (150 seconds). In other words, valid time is any time value in the last 1500 seconds (or 25 minutes).

Validate that incoming packet has arrived from the correct engine id and is using a correct combination of privacy and authentication values.

Cached authentication key

Authentication digest to use in authNoPriv and authPriv security combinations. For available authentication digests, see AuthenticationDigests enumeration.

Authentication secret (or authentication password)

Context engine id. By default, this value is set to authoritative engine id value unless specifically set to a different value here.

Context name. By default this value is a 0 length string (no context name). Set this value if you require it to be defined in ScopedPdu.

Authoritative engine boots value

Authoritative engine id

Authoritative engine time value

Time stamp when authoritative engine time value was last refreshed with data from the agent. This value is used to calculate up to date authoritative agent time value without having to repeat discovery process every 150 seconds.

Maximum message size. This value is by default set to 64KB and then updated by the maximum message size value in the response from the agent. This value should be the smallest message size supported by both the agent and manager.

Cached privacy key

Privacy protocol to use. For available protocols, see PrivacyProtocols enumeration.

Privacy secret (or privacy password)

Reportable option flag. Set to true by default. This flag controls if reportable flag will be set in the packet. When this flag is set in the packet, agent will respond to invalid requests with Report packets. Without this flag being set, all invalid requests are silently dropped by the agent.

Security name value, or user name.

Authentication method. Acceptable values are members of AuthenticationDigests enum.

Get/Set cached authentication key value

Authentication secret. Secret length depends on the hash algorithm selected.

Get SNMP version 3 context engine id. By default, this value will be set to the same engine id as authoritative engine id (EngineId). I haven't see a scenario where this value needs to be different by a manager but now there is an option to do it. To use the default operation, do not set this value or, if you've already set it, reset it to null (object.ContextEngineId.Reset()).

Get SNMP version 3 context name

SNMP version 3 agent engine boots value

Agent authoritative engine id

SNMP version 3 agent engine time value.

Check if cached privacy or authentication keys are available

Get SNMP version 3 maximum message size object

Privacy protocol used. Acceptable values are members of PrivacyProtocols enum.

Get/Set cached privacy key value

Privacy secret. Length of the secret is dependent on the selected privacy method.

Get/Set reportable flag status in the SNMP version 3 packet.

Security or user name configured on the SNMP version 3 agent.

SNMP version. Only acceptable version is Ver3
