CentOS 7.0 - man page for snmpget (centos section 1)

SNMPGET(1)				     Net-SNMP				       SNMPGET(1)

NAME
       snmpget - communicates with a network entity using SNMP GET requests

SYNOPSIS
       snmpget [COMMON OPTIONS] [-Cf] AGENT 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 takes the common options described in the snmpcmd(1)
       manual page.  Note that snmpget REQUIRES an argument specifying the agent to query and  at
       least one OID argument, as described there.

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 mal-
       formed.	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: root@localhost

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