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).
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:
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.
