snmpset — Set the value of an SNMP object
$hostname,$community,$object_id,$type,$value,$timeout = -1,$retries = -1
snmpset() is used to set the value of an SNMP object
specified by the object_id.
hostnameThe hostname of the SNMP agent (server).
communityThe write community.
object_idThe SNMP object id.
typeMIB her nesne kimliğini türünü tanımlar. Aşağıdaki listeden tek bir karakter olarak belirtilmelidir.
| = | 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_TYPES tanımlanmışsa
aşağıdakiler de geçerlidir:
| 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 type parameter 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)}":
See examples section for more details.
valueThe new value.
timeoutThe number of microseconds until the first timeout.
retriesThe number of times to retry if timeouts occur.
Başarı durumunda true, başarısızlık durumunda false döner.
If the SNMP host rejects the data type, an E_WARNING message like "Warning: Error in packet. Reason: (badValue) The value given has the wrong type or length." is shown. If an unknown or invalid OID is specified the warning probably reads "Could not add variable".
Örnek 1 Using snmpset()
<?php

?>Örnek 2 Using snmpset() for setting BITS SNMP object id
<?php
snmpset("localhost", "public", 'FOO-MIB::bar.42', 'b', '0 1 2 3 4');
// or
snmpset("localhost", "public", 'FOO-MIB::bar.42', 'x', 'F0');
