SNMP::set

Bağımsız Değişkenler

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.

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_TYPES tanımlanmışsa 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 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)}":

• 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.
