Açıklama
Requests remote SNMP agent setting the value of

Bağımsız Değişkenler
-
objectId -
The SNMP object id
When count of OIDs in object_id array is greater than max_oids object property set method will have to use multiple queries to perform requested value updates. In this case type and value checks are made per-chunk so second or subsequent requests may fail due to wrong type or value for OID requested. To mark this a warning is raised when count of OIDs in object_id array is greater than max_oids.

type -
MIB her nesne kimliğini türünü tanımlar. Aşağıdaki listeden tek bir karakter olarak belirtilmelidir.
types = Tür MIB'den alınır. i INTEGER u INTEGER s STRING x HEX STRING d DECIMAL STRING n NULLOBJ o OBJID t TIMETICKS a IPADDRESS b BITS SNMP kütüphanesi derlenirken
OPAQUE_SPECIAL_TYPEStanımlanmışsa aşağıdakiler de geçerlidir:types U unsigned int64 I signed int64 F float D double Most of these will use the obvious corresponding ASN.1 type. 's', 'x', 'd' and 'b' are all different ways of specifying an OCTET STRING value, and the 'u' unsigned type is also used for handling Gauge32 values.
If the MIB-Files are loaded by into the MIB Tree with "snmp_read_mib" or by specifying it in the libsnmp config, '=' may be used as the
typeparameter for all object ids as the type can then be automatically read from the MIB.Note that there are two ways to set a variable of the type BITS like e.g. "SYNTAX BITS {telnet(0), ftp(1), http(2), icmp(3), snmp(4), ssh(5), https(6)}":
- Using type "b" and a list of bit numbers. This method is not recommended since GET query for the same OID would return e.g. 0xF8.
- Using type "x" and a hex number but without(!) the usual "0x" prefix.
See examples section for more details.

value -
The new value.
If objectId is string, both
type and value must be
string too. If objectId is array
value must be equal-sized array containing
corresponding values, type may be either
string (it's value will be used for all
objectId-value pairs) or
equal-sized array with per-OID value. When any other parameters' combinations are
used, a number of E_WARNING messages may be shown with detailed description.

Hatalar/İstisnalar
This method do not throw any exceptions by default.
To enable throwing an SNMPException exception when some of library errors occure
user should set exceptions_enabled
SNMP class parameter to corresponding value. See
SNMP::$exceptions_enabled explanation for more details.
Örnekler
Örnek 1 Set single SNMP object id
<?php
$session = new SNMP(SNMP::VERSION_2C, "127.0.0.1", "private");
$session->set('SNMPv2-MIB::sysContact.0', 's', "Nobody");
?>Örnek 2 Set multiple values using single SNMP::set() call
<?php
$session = new SNMP(SNMP::VERSION_2C, "127.0.0.1", "private");
$session->set(array('SNMPv2-MIB::sysContact.0', 'SNMPv2-MIB::sysLocation.0'), array('s', 's'), array("Nobody", "Nowhere"));
// or
$session->set(array('SNMPv2-MIB::sysContact.0', 'SNMPv2-MIB::sysLocation.0'), 's', array("Nobody", "Nowhere"));
?>Örnek 3 Using SNMP::set() for setting BITS SNMP object id
<?php
$session = new SNMP(SNMP::VERSION_2C, "127.0.0.1", "private");
$session->set('FOO-MIB::bar.42', 'b', '0 1 2 3 4');
// or
$session->set('FOO-MIB::bar.42', 'x', 'F0');
?>
