snmpset

Parameter-Liste

host

Der Hostname des SNMP-Agent (Server).

community

Die "write community".

object_id

Die SNMP-Objektkennung.

type

The MIB defines the type of each object id. It has to be specified as a single character from the below list.

types

=	The type is taken from the MIB
i	INTEGER
u	INTEGER
s	STRING
x	HEX STRING
d	DECIMAL STRING
n	NULLOBJ
o	OBJID
t	TIMETICKS
a	IPADDRESS
b	BITS

If OPAQUE_SPECIAL_TYPES was defined while compiling the SNMP library, the following are also valid:

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

Der neue Wert.

timeout

Die Zahl der Mikrosekunden bis zum ersten Timeout.

retries

Die Anzahl der Wiederholungsversuche, wenn Timeouts auftreten.
