-
hostname
-
The hostname of the SNMP agent (server).
-
community
-
The write community.
-
object_id
-
The SNMP object id.
-
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.
-
timeout
-
The number of microseconds until the first timeout.
-
retries
-
The number of times to retry if timeouts occur.

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".
