This section describes the behavior of a SNMPv2 entity when it communicates with a SNMPv2 party for which the privacy protocol is administratively specified as the Symmetric Privacy Protocol. Insofar as the behavior of a SNMPv2 entity when transmitting a protocol message is defined generically in , only those aspects of that behavior that are specific to the Symmetric Privacy Protocol are described below. In particular, this section describes the encapsulation of a SNMPv2 authenticated management communication into a SNMPv2 private management communication.
According to Section 3.1 of , a SnmpPrivMsg value is constructed during Step 5 of generic processing. In particular, it states the privData component is constructed according to the privacy protocol identified for the SNMPv2 party receiving the message. When the relevant privacy protocol is the Symmetric Privacy Protocol, the procedure performed by a SNMPv2 entity whenever a management communication is to be transmitted by a SNMPv2 party is as follows.
As set forth in , the SnmpPrivMsg value is then serialized and transmitted to the receiving SNMPv2 party.
