snmp3_set

参数

host

The hostname of the SNMP agent (server).

sec_name

the security name, usually some kind of username

sec_level

the security level (noAuthNoPriv|authNoPriv|authPriv)

auth_protocol

the authentication protocol (MD5 or SHA)

auth_passphrase

the authentication pass phrase

priv_protocol

the privacy protocol (DES or AES)

priv_passphrase

the privacy pass phrase

object_id

The SNMP object id.

type

MIB 定义了各个对象id的类型. 必须是下面列出的单个字符之一.

类型

=	MIB类型
i	INTEGER
u	INTEGER
s	STRING
x	HEX STRING
d	DECIMAL STRING
n	NULLOBJ
o	OBJID
t	TIMETICKS
a	IPADDRESS
b	BITS

如果在编译SNMP库时定义了OPAQUE_SPECIAL_TYPES , 那么下列值是合法的:

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.
