snmpset - communicates with a network entity using SNMP SET requests
snmpset [COMMON OPTIONS] AGENT OID TYPE VALUE [OID TYPE VALUE]...
snmpset is an SNMP application that uses the SNMP SET request to set
information on a network entity. One or more object identifiers (OIDs) must be
given as arguments on the command line. A type and a value to be set must
accompany each object identifier. Each variable name is given in the format
specified in
variables(5).
The
TYPE is a single character, one of:
- i
- INTEGER
- u
- UNSIGNED
- s
- STRING
- x
- HEX STRING
- d
- DECIMAL STRING
- n
- NULLOBJ
- o
- OBJID
- t
- TIMETICKS
- a
- IPADDRESS
- b
- BITS
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 you have the proper MIB file loaded, you can, in most cases, replace the type
with an '=' sign. For an object of type OCTET STRING this will assume a string
like the 's' type notation. For other types it will do "The Right
Thing".
For example:
snmpset -c private -v 1 test-hub system.sysContact.0 s
[email protected]
ip.ipforwarding.0 = 2
will set the variables sysContact.0 and ipForwarding.0:
system.sysContact.0 = STRING: "
[email protected]"
ip.ipForwarding.0 = INTEGER:
not-forwarding(2)
If the network entity has an error processing the request packet, an error
packet will be returned and a message will be shown, helping to pinpoint in
what way the request was malformed.
snmpset takes the common options described in the
snmpcmd(1)
manual page. Note that
snmpset REQUIRES an argument specifying the
agent to query and at least one set of OID/type/value arguments, as described
in there.
