TEMPUSLXUNISON-MIB
Which is located on your Tempus LX in this ASCII file:
/usr/local/share/snmp/mibs/TEMPUSLXUNISON-MIB.txt
In addition to a complete set of NTP and GPS status objects, the MIB defines four SMIv2 notification
objects:
• NTP Leap Indicator Bits status change
• NTP Stratum change
• GPS Fault Status change
• GPS Time Figure of Merit change
Invocation of the
SNMP daemon
The SNMP daemon,
snmpd
is started from the
/etc/rc.d/rc.local
system start-up script with this line:
snmpd -m “$MIBNAME” -Ls d -c /etc/snmpd.conf
By default, it will listen on port 161 for SNMP queries from the network management system. If
you would like to have it listen on another port, you could edit the file by adding
-p port
to the
end of this line, where
port
is the number of the port you would like for the agent to listen on. If
you would like to disable starting of the
snmpd
daemon altogether, you can either remove this line
or place a
#
character at the beginning of the line so that it will not be executed. (A very compact
editor with WordStar command keystrokes is available on the system for this purpose:
edit
. If you
start
edit
without giving it a file name to open, it will display its help screen, showing the supported
keystrokes.)
IMPORTANT
After editing /etc/rc.d/rc.local , you must copy it to the /boot/etc/rc.d directory and re-boot the system.
It is very important to retain the access mode for the file, so be sure to use
cp -p
when performing the
copy. During the boot process, the files contained in the /boot/etc/rc.d directory are copied to the work-
ing /etc/rc.d directory on the system RAM disk. In this way the factory defaults are overwritten.
Quick Start Configuration
-- SNMPv1/v2c
You should be able to compile the TEMPUSLXUNISON-MIB file on your SNMP management
system and access the variables defined therein. The factory default community names are “Tempus-
LXUnison” for the read-only community and “endrun_1” for the read-write community. This is all
that is required for operation under v1 and v2c of SNMP. You can, and should, change the default
community names by editing
/etc/snmpd.conf
and modifying these two lines:
rwcommunity endrun_1
rocommunity TempusLXUnison
