snmpget

communicates with a network entity using SNMP GET Requests 

Command


SYNOPSIS

snmpget [COMMON_OPTION] [-Cf] AGENT OID [OID]...


DESCRIPTION

The snmpget utility 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 snmp_variables.

For example:

$ snmpget -v 1 -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):

With the -Cf option 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 reference 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 -v 1 -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 malformed. 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 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

$ snmpget -v1 -Cf -c public localhost system.sysUpTime system.sysContact.0
