SNMPGET(1)                         Net-SNMP                         SNMPGET(1)




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).

       For example:

       snmpget -c public zeus system.sysDescr.0

       will retrieve the variable system.sysDescr.0:

       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.


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. Here is an example
               (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

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

       snmpget -v1 -c public localhost system.sysUpTime system.sysContact.0
       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 specified the application will not try to fix the
               PDU for you.

       In addition to this option, snmpget takes the common options  described
       in the snmpcmd(1) manual page.
