SYSTEM ADMINISTRATION
CHAPTER 4: SYSTEM ADMINISTRATION
In Total Set Vars:
The total number of MIB objects which have been altered
successfully by the SNMP protocol entity as the result of
receiving valid SNMP Set-Request PDUs.
Silent Drops:
The total number of GetRequest PDUs, GetNextRequest
PDUs,GetBulkRequest PDUs, SetRequest PDUs, and
InformRequest PDUs delivered to the SNMP entity which were
silently dropped because the size of a reply containing an
alternate Response PDU with an empty variable-bindings field
was greater than either a local constraint or the maximum
message size associated with the originator of the request.
Proxy Drops:
The total number of GetRequest PDUs, GetNextRequest
PDUs,GetBulkRequest PDUs, SetRequest PDUs, and
InformRequest PDUs delivered to the SNMP entity which were
silently dropped because the transmission of the (possibly
translated) message to a proxy target failed in a manner (other
than a time-out) such that no Response PDU could be returned.
Unknown Security
Models:
The total number of packets received by the SNMP engine
which were dropped because they referenced a securityModel
that was not known to or supported by the SNMP engine.
Invalid Messages:
The total number of packets received by the SNM engine which
were dropped because there were invalid or inconsistent
components in the SNMP message, for example, noauth/priv.
Multinet4 allows noauth/nopriv, auth/nopriv, and auth/priv but
does not allow noauth/priv.
Unknown Contexts:
The total number of packets received by the SNMP engine
which were dropped because the context contained in the
message was unknown.
Unavailable Contexts:
The total number of packets received by the SNMP engine
which were dropped because the context contained in the
message was unavailable.
Unknown PDU
Handlers:
The total number of packets received by the SNMP engine
which were dropped because the PDU contained in the packet
could not be passed to an application responsible for handling
the pduType, for example, no SNMP application had registered
for the proper combination of the contextEngineID and the
pduType.
Unsupported Security
Levels:
The total number of packets received by the SNMP engine
which were dropped because they requested a securityLevel
that was unknown to the SNMP engine or otherwise
unavailable.
