- .TH SNMPGET 1 "08 Feb 2002" VVERSIONINFO "Net-SNMP"
- .UC 4
- .SH NAME
- snmpget - communicates with a network entity using SNMP GET requests
- .SH SYNOPSIS
- .B snmpget
- [COMMON OPTIONS] [-Cf] OID [OID]...
- .SH DESCRIPTION
- .B 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
- .IR variables(5) .
- .PP
- For example:
- .PP
- snmpget -c public zeus system.sysDescr.0
- .PP
- will retrieve the variable system.sysDescr.0:
- .PP
- system.sysDescr.0 = "SunOS zeus.net.cmu.edu 4.1.3_U1 1 sun4m"
- .PP
- 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.
- .SH "OPTIONS"
- .TP 8
- .B -Cf
- If
- .B -Cf
- is
- .I not
- specified, some applications
- .RB ( 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):
- .PP
- .nf
- snmpget -v1 -Cf -c public localhost system.sysUpTime system.sysContact.0
- .BR
- 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
- .fi
- .IP "" 8
- With the
- .B
- -Cf
- specified the application will not try to fix the PDU for you.
- .PP
- In addition to this option,
- .B snmpget
- takes the common options described in the
- .I snmpcmd(1)
- manual page.
- .SH "SEE ALSO"
- snmpcmd(1), variables(5).
