subagents.
13.4 Configuring SNMP
You can configure SNMP in three ways, which may be used in combination:
• Using the standard TCPIP$CONFIG.COM procedure and the SET
CONFIGURATION SNMP command. These methods write configuration
information into the TCP/IP Services configuration database file
TCPIP$CONFIGURATION.DAT. Section 13.4.1 describes how to use
TCPIP$CONFIG to initially configure SNMP.
• Editing the text configuration file TCPIP$VMS_SNMP_CONF.DAT, located
in the SYS$SYSDEVICE:[TCPIP$SNMP] directory. This method provides
options not available with TCPIP$CONFIG and the SET CONFIGURATION
SNMP command.
Note
Although the OpenVMS SNMP configuration file is based on the UNIX
implementation, there are several important differences. For example,
the option snmpEnableAuthenTraps is not used. See the description of
specific options for details.
The configuration file is described in Section 13.4.3.
• Assigning logical names. This method provides the same options as the text
configuration file. For more information, see Section 13.4.3.
If the same option is defined in multiple ways, the configuration methods are
resolved as follows:
• Values specified through TCPIP$CONFIG or SET CONFIGURATION SNMP
take precedence over any options specified in the TCPIP$VMS_SNMP_
CONF.DAT file or set with logical names.
• Values specified in the TCPIP$VMS_SNMP_CONF.DAT file take precedence
over logical name settings.
13.4.1 Initial SNMP Configuration
SNMP runs as a TCP/IP service. To be sure all SNMP-related files are included
and enabled properly, run the TCPIP$CONFIG configuration procedure to
configure SNMP initially or to set up a new configuration. When you enable
SNMP during TCPIP$CONFIG, the procedure prompts you for the correct
parameters.
