One or more fully qualified object identifiers 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 .I snmpget zeus public system.sysDescr.0 .PP will retrieve the variable system.sysDescr.0: .PP .I 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. .PP .SH "OPTIONS" .IP -Cf If -Cf is not specified, some applications (E.G., snmpget, snmpgetnext, snmpwalk, etc) 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. Example (system.sysUptime is an incomplete OID request for agents as it needs the .0 index appended to it): .nf snmpget -v 1 -Cf localhost public 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 -v 1 localhost public 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 = root@localhost .fi .IP With the -Cf specified the application will not try to fix the PDU for you. .SH "SEE ALSO" snmpcmd(1), variables(5).
