Statistics Description
snmpInASNParseErrs The total number of ASN.1 (Abstract Syntax Notation One) or BER (Basic
Encoding Rules), errors encountered by the SNMP protocol entity when
decoding SNMP messages received.
The Open Systems Interconnection (OSI) 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.
snmpEnableAuthTraps An object to enable or disable the authentication traps generated by this switch.
snmpOutPkts The total number of SNMP messages which were passed from the SNMP
protocol entity to the transport service.
snmpInBadTypes The total number of SNMP messages which failed ASN.1 parsing.
snmpInTooBigs The total number of SNMP Protocol Data Units (PDUs) that were delivered to
the SNMP protocol entity and for which the value of the error-status field is too
big.
snmpInNoSuchNames The total number of SNMP Protocol Data Units (PDUs) that were delivered to
the SNMP protocol entity and for which the value of the error-status field is
noSuchName.
snmpInBadValues The total number of SNMP Protocol Data Units (PDUs) that were delivered to
the SNMP protocol entity and for which the value of the error-status field is
badValue.
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.
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.
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).
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).
snmpInGetRequests The total number of SNMP Get-Request Protocol Data Units (PDUs), which
have been accepted and processed by the SNMP protocol entity.
snmpInGetNexts The total number of SNMP Get-Next Protocol Data Units (PDUs), which have
been accepted and processed by the SNMP protocol entity.
snmpInSetRequests The total number of SNMP Set-Request Protocol Data Units (PDUs), which have
been accepted and processed by the SNMP protocol entity.
snmpInGetResponses The total number of SNMP Get-Response Protocol Data Units (PDUs), which
have been accepted and processed by the SNMP protocol entity.
snmpInTraps The total number of SNMP Trap Protocol Data Units (PDUs), which have been
accepted and processed by the SNMP protocol entity.
snmpOutTooBigs 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
too big.
snmpOutNoSuchNames 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 is
noSuchName.
snmpOutBadValues 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
badValue.
snmpOutReadOnlys Not in use.
