3.1. Generating a Request
This section describes the procedure followed by a SNMPv2
entity whenever either a management request or a trap
notification is to be transmitted by a SNMPv2 party.
- A SnmpMgmtCom value is constructed for which the srcParty
component identifies the originating party, for which the
dstParty component identifies the receiving party, for
which the context component identifies the desired SNMPv2
context, and for which the pdu component represents the
desired management operation.
- The local database of party information is consulted to
determine the authentication protocol and other relevant
information for the originating and receiving SNMPv2
parties.
- A SnmpAuthMsg value is constructed with the following
properties:
Its authInfo component is constructed according to
the authentication protocol specified for the
originating party.
In particular, if the authentication protocol for
the originating SNMPv2 party is identified as
noAuth, then this component corresponds to the
OCTET STRING value of zero length.
Its authData component is the constructed SnmpMgmtCom
value.
- The local database of party information is consulted to
determine the privacy protocol and other relevant
information for the receiving SNMPv2 party.
- A SnmpPrivMsg value is constructed with the following
properties:
Its privDst component identifies the receiving
SNMPv2 party.
Its privData component is the (possibly encrypted)
serialization of the SnmpAuthMsg value according to
the conventions of [5].
In particular, if the privacy protocol for the
receiving SNMPv2 party is identified as noPriv,
then the privData component is unencrypted.
Otherwise, the privData component is processed
according to the privacy protocol.
- The constructed SnmpPrivMsg value is serialized according
to the conventions of [5].
- The serialized SnmpPrivMsg value is transmitted using the
transport address and transport domain for the receiving
SNMPv2 party.
Note that the above procedure does not include any application
of any SNMPv2 access control policy (see section 2.13).
