Enterprise Management
Information Base (MIB)
In addition to providing the SNMP variables contained in MIB-II as described in RFC-1213, EndRun
Technologies has implemented an enterprise MIB using the syntax of the SMI version 2 (SMIv2) as
described in RFC-2578:
SONOMA-MIB
Which is located on your Sonoma in this ASCII file:
/usr/local/share/snmp/mibs/SONOMA-MIB.txt
In addition to a complete set of NTP and Receiver (GPS or CDMA) status objects, the MIB defines
four SMIv2 notification objects:
• NTP Leap Indicator Bits status change
• NTP Stratum change
• Receiver Fault Status change
• Receiver Time Figure of Merit change
Invocation of the
SNMP daemon
The SNMP daemon,
snmpd
is started from the
/etc/rc.d/rc.snmpd
system start-up script. 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 and change the port number in the argument list
being passed to
snmpd
when it is started.
IMPORTANT
After modifying
/etc/rc.d/rc.snmpd
, you must copy it to the
/boot/etc/rc.d
directory and reboot the sys-
tem. 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
working /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 SONOMA-MIB file on your SNMP management system and
access the variables defined therein. The factory default community names are “Sonoma” 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.
