OBJID

s

value

The data value.

variable_name

The variable name in the format specified in the file mib.txt.

Description:

The snmpset utility uses the SET request to set 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:

Set the variable sysContact.0 to “John Doe”:

Using SNMPv1

snmpset -v 1 netdev-kbox.cc.cmu.edu public system.sysContact.0 s "John Doe"

Using SNMPv2

snmpset netdev-kbox.cc.cmu.edu manager_party agent_party agent_context
  system.sysContact.0 s "John Doe"

The output is similar to:

system.sysContact.0 = "John Doe"

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 snmpset displays a message to help pinpoint how the request was malformed.
