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 le:
/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 denes
four SMIv2 notication 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 le 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 le on your SNMP management system and
access the variables dened 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.
