Represents SNMP session.
Maximum OID per GET/SET/GETBULK request
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.
Read-only property with remote agent configuration: hostname, port, default timeout, default retries count
No SNMP-specific error occured.
A generic SNMP error occured.
Request to SNMP agent timed out.
SNMP agent returned an error in reply.
SNMP agent faced OID cycling reporning non-increasing OID while executing (BULK)WALK command. This indicates bogus remote SNMP agent.
