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.0is printed as:
syscontact.0This ID:
udp.udpTable.udpEntry.udpLocalAddress.0.0.0.161is 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.
