NAME

snmpget – communicates with a network entity using SNMP GET requests
 

SYNOPSIS

snmpget

[COMMON OPTIONS] [-Cf] OID [OID]…
 

DESCRIPTION

snmpget

is an SNMP application that uses the SNMP GET request to query for
information on a network entity. One or more object identifiers
(OIDs) may be given as arguments on the command line. Each variable
name is given in the format specified in
variables(5).

 

OPTIONS


-Cf


If
-Cf

is
not

specified, some applications
(snmpdelta, snmpget, snmpgetnext and snmpstatus)

will try to fix errors returned by the agent that you were talking to
and resend the request. The only time this is really useful is if you
specified a OID that didn’t exist in your request and you’re using
SNMPv1 which requires "all or nothing" kinds of requests.


In addition to this option,
snmpget

REQUIRES options and agent arguments, as described in the
snmpcmd(1)

manual page.
 

EXAMPLES

The command:


    snmpget -c public zeus system.sysDescr.0

will retrieve the variable system.sysDescr.0 from the host
zeus

using the community string
public

:


    system.sysDescr.0 = "SunOS zeus.net.cmu.edu 4.1.3_U1 1 sun4m"

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. If there were other
variables in the request, the request will be resent without the bad
variable.

Here is another example. The -c and -v options are defined in the
snmpcmd(1)

manual page. (Note that system.sysUpTime is an incomplete
OID, as it needs the .0 index appended to it):


snmpget -v1 -Cf -c public localhost system.sysUpTime system.sysContact.0

This example will return the following:


Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
This name doesn’t exist: system.sysUpTime

Similarly, the command:


snmpget -v1 -c public localhost system.sysUpTime system.sysContact.0

Will return:


Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
This name doesn’t exist: system.sysUpTime

system.sysContact.0 = STRING: [email protected]

With the
-Cf

flag specified the application will not try to fix the PDU for you.
