Controls the method how the SNMP values will be returned
SNMP_VALUE_LIBRARY | The return values will be as returned by the Net-SNMP library. |
SNMP_VALUE_PLAIN | The return values will be the plain value without the SNMP type hint. |
SNMP_VALUE_OBJECT |
The return values will be objects with the properties "value" and "type", where the latter
is one of the SNMP_OCTET_STR, SNMP_COUNTER etc. constants. The
way "value" is returned is based on which one of SNMP_VALUE_LIBRARY ,
SNMP_VALUE_PLAIN is set

Value of quick_print
within the NET-SNMP library
Sets the value of quick_print
within the NET-SNMP library. When this
is set (1), the SNMP library will return 'quick printed' values. This
means that just the value will be printed. When quick_print
is not
enabled (default) the UCD SNMP library prints extra information
including the type of the value (i.e. IpAddress or OID). Additionally,
if quick_print is not enabled, the library prints additional hex values
for all strings of three characters or less.
Controls the way enum values are printed
Parameter toggles if walk/get etc. should automatically lookup enum values in the MIB and return them together with their human readable string.
Controls OID output format
SNMP_OID_OUTPUT_FULL | .iso.org.dod.internet.mgmt.mib-2.system.sysUpTime.sysUpTimeInstance |
SNMP_OID_OUTPUT_NUMERIC | .1.3.6.1.2.1.1.3.0 |
SNMP_OID_OUTPUT_MODULE | DISMAN-EVENT-MIB::sysUpTimeInstance |
SNMP_OID_OUTPUT_SUFFIX | sysUpTimeInstance |
SNMP_OID_OUTPUT_UCD | system.sysUpTime.sysUpTimeInstance |
SNMP_OID_OUTPUT_NONE | Undefined |
Controls disabling check for increasing OID while walking OID tree
Some SNMP agents are known for returning OIDs out
of order but can complete the walk anyway. Other agents return OIDs
that are out of order and can cause SNMP::walk()
to loop indefinitely until memory limit will be reached.
PHP SNMP library by default performs OID increasing check and stops
walking on OID tree when it detects possible loop with issuing warning
about non-increasing OID faced.
Set oid_increasing_check to FALSE
to disable this
check.
Controls which failures will raise SNMPException instead of
warning. Use bitwise OR'ed SNMP::ERRNO_*
constants.
By default all SNMP exceptions are disabled.
Read-only property with remote agent configuration: hostname, port, default timeout, default retries count
SNMP::ERRNO_NOERROR
No SNMP-specific error occurred.
SNMP::ERRNO_GENERIC
A generic SNMP error occurred.
SNMP::ERRNO_TIMEOUT
Request to SNMP agent timed out.
SNMP::ERRNO_ERROR_IN_REPLY
SNMP agent returned an error in reply.
SNMP::ERRNO_OID_NOT_INCREASING
SNMP agent faced OID cycling reporning non-increasing OID while executing (BULK)WALK command. This indicates bogus remote SNMP agent.
SNMP::ERRNO_OID_PARSING_ERROR
Library failed while parsing OID (and/or type for SET command). No queries has been made.
SNMP::ERRNO_MULTIPLE_SET_QUERIES
Library will use multiple queries for SET operation requested. That means that operation will be performed in a non-transaction manner and second or subsequent chunks may fail if a type or value failure will be faced.
SNMP::ERRNO_ANY
All SNMP::ERRNO_* codes bitwise OR'ed.
