Configuring SNMPv1
Trap Generation
To have your Tempus LX send SNMPv1 traps (RFC-1215) you must configure the community and
destination for SNMPv1 traps by uncommenting and editing this line in
/etc/snmpd.conf
:
trapsink xxx.xxx.xxx.xxx trapcommunity trapport
where
trapcommunity
should be replaced by your community, and
xxx.xxx.xxx.xxx
is the IP
address or hostname of the destination host for receiving the traps generated by the Tempus LX. By
default, the trap will be sent to port 162. You may optionally add another parameter,
trapport
to
the end of the above line to override the default port setting. Otherwise leave it blank.
Note: Though the agent will recognize multiple
trapsink
lines within /etc/snmpd.conf and send the
generic SNMP coldStart or authenticationFailure traps to each destination, the enterprise trap genera-
tion mechanism of the Tempus LX will only send a trap to the last declared
trapsink
in the file.
Configuring SNMPv2c
Notifications and Informs
To have your Tempus LX send SNMPv2c notifications (SMIv2, RFC-2578) or informs, you must
configure the communities and destinations by uncommenting and editing one or both of these lines
in
/etc/snmpd.conf
:
trap2sink xxx.xxx.xxx.xxx trap2community trap2port
informsink xxx.xxx.xxx.xxx informcommunity informport
where
trap2community
and
informcommunity
should be replaced by your communities, and
xxx.xxx.xxx.xxx
is the IP address or hostname of the destination host for receiving the notifica-
tions or informs generated by the Tempus LX. By default, the v2c trap or inform will be sent to port
162. You may optionally add another parameter,
trap2port
or
informport
to the ends of the
above lines to override the default port setting. Otherwise leave it blank.
Note: Though the agent will recognize multiple
trap2sink
or
informsink
lines within
/etc/
snmpd.conf and send the generic SNMP coldStart or authenticationFailure notifications and informs
to each destination, the enterprise notification/inform generation mechanism of the Tempus LX will
only send a notification to the last declared
trap2sink
and an inform to the last declared
inform-
sink
in the file.
IMPORTANT
After editing /etc/snmpd.conf , you must copy it to the /boot/etc directory and re-boot the system. It is
very important to retain the access mode for the file (readable only by
root
), so be sure to use
cp -p
when performing the copy. During the boot process, the files contained in the /boot/etc directory are cop-
ied to the working
/etc
directory on the system RAM disk. In this way the factory defaults are overwritten.
Configuration of SNMPv3
If you are planning to use SNMPv3, you should definitely make use of the two resources mentioned
previously (NET-SNMP website and Essential SNMP ) and study them carefully. There are rather
elaborate configuration options available when you are using v3. The instruction presented here will
