Table 50 SNMP Statistics
Statistic Description
snmpInReadOnlys The total number of valid SNMP Protocol Data Units (PDUs), which were delivered to the
SNMP protocol entity and for which the value of the error-status field is ‘read-Only’. It
should be noted that it is a protocol error to generate an SNMP PDU, which contains the
value ‘read-Only’ in the error-status field. As such, this object is provided as a means of
detecting incorrect implementations of the SNMP.
snmpOutReadOnlys Not in use.
snmpInGetResponses The total number of SNMP Get-Response Protocol Data Units (PDUs) that were delivered
to the SNMP protocol entity.
snmpOutGetResponses The total number of SNMP Get-Response Protocol Data Units (PDUs), which have been
generated by the SNMP protocol entity.
snmpInGenErrs The total number of SNMP Protocol Data Units (PDUs), which were delivered to the
SNMP protocol entity and for which the value of the error-status field is
genErr.
snmpOutGenErrs The total number of SNMP Protocol Data Units (PDUs), which were generated by the
SNMP protocol entity and for which the value of the error-status field is
genErr.
snmpInTraps The total number of SNMP Trap Protocol Data Units (PDUs), which have been accepted
and processed by the SNMP protocol entity.
snmpOutTraps The total number of SNMP Trap Protocol Data Units (PDUs), which have been generated
by the SNMP protocol entity.
snmpInBadVersions The total number of SNMP Messages, which were delivered to the SNMP protocol entity
and were for an unsupported SNMP version.
snmpInTotalReqVars The total number of MIB objects which have been retrieved successfully by the SNMP
protocol entity as a result of receiving valid SNMP Get- Request and Get-Next Protocol
Data Units (PDUs).
snmpInBadCtyNames The total number of SNMP Messages delivered to the SNMP entity that used an SNMP
community name not known to the said entity (the switch).
snmpInTotalSetVars The total number of MIB objects, which have been altered successfully by the SNMP
protocol entity as a result of receiving valid SNMP Set-Request Protocol Data Units
(PDUs).
snmpInBadCtyUses The total number of SNMP Messages delivered to the SNMP protocol entity that
represented an SNMP operation that was not allowed by the SNMP community named
in the Message.
snmpEnableAuthTraps An object to enable or disable the authentication traps generated by this entity (the
switch).
snmpInASNParseErrs The total number of ASN.1 or BER errors encountered by the SNMP protocol entity
when decoding SNMP Messages received.
Note: OSI’s method of specifying abstract objects is called ASN.1 (Abstract Syntax
Notation One, defined in X.208), and one set of rules for representing such objects as
strings of ones and zeros is called the BER (Basic Encoding Rules, defined in X.209).
ASN.1 is a flexible notation that allows one to define a variety of data types, from
simple types such as integers and bit strings to structured types such as sets and
sequences. BER describes how to represent or encode values of each ASN.1 type as a
string of eight-bit octets.
snmpInBadTypes The total number of SNMP Messages which failed ASN parsing.
