`snmpget`

Communicate with a network entity using SNMP GET requests

Syntax:

snmpget [-d] [-p port] [-r retry] [-t timeout] 
        -v 1 host community variable_name
        [variable_name]

snmpget [-d] [-p port] [-r retry] [-t timeout]
        [-v 2] host noAuth variable_name
        [variable_name]

snmpget [-d] [-p port] [-r retry] [-t timeout]
        [-v 2] host scrparty dstparty context
        variable_name [variable_name]

Options:

-d: Dump input and output packets.
-p port: Specify the destination port number.
-r retry: Specify the number of retries.
-t timeout: Specify timeout (in seconds).
-v 1|2: SNMP version (default is 2).
community: The community name for the transaction with the remote system.
context: The collection of object resources that can be queried by the dstparty.
dstparty: The name of the party providing information.
host: An Internet address specified in dot notation or a hostname.
srcparty: The name of the party requesting information.
variable_name: The variable name in the format specified in the file mib.txt.

The snmpget utility uses the GET request to query for information about a network entity. You can specify one or more fully qualified object identifiers in the format specified in the file mib.txt.

If you're using SNMP version 2, the following files must be configured:

/etc/acl.conf
/etc/context.conf
/etc/party.conf
/etc/snmpd.conf (required only if you change the default location of your config files)

For a description on how to configure the files please see the file page for each of the configuration files listed above. If you wish to change the location of your configuration files, you must include a snmpd.conf file.

Examples:

Retrieve the variables sysDescr.0 and sysUpTime.0:

Using SNMPv1

snmpget -v 1 netdev-kbox.cc.cmu.edu public \
system.sysDescr.0 system.sysUpTime.0

Using SNMPv2

snmpget \ netdev-kbox.cc.cmu.edu manager_party \
agent_party agent_context system.sysDescr.0 \
system.sysUpTime.0

The output is similar to:

Name: system.sysDescr.0
OCTET STRING- (ascii):   Kinetics FastPath2

Name: system.sysUpTime.0
Timeticks: (2270351) 6:18:23

Environment variables:

MIBFILE

Specify the location of the mib.txt file. For example, MIBFILE=path/mib.txt (the default path is /etc).

SUFFIX

If SUFFIX exists in your environment, all object IDs with a symbolic name are printed with only the last element. Examples:

This ID:

system.syscontact.0

is printed as:

syscontact.0

This ID:

udp.udpTable.udpEntry.udpLocalAddress.0.0.0.161

is printed as:

udpLocalAddress.0.0.0.161

Errors:

If the network entity has an error processing the request packet, an error packet is returned and snmpget displays a message to help pinpoint how the request was malformed. If you've specified other variables, snmpget resends the request without the variable that caused the problem.
