How to use SNMP with berofix


The bero*fix SNMP server can be started by enabling the checkbox SNMP enabled in section Management -> Remote Management -> SNMP of the bero*fix GUI.

It will then run on standard port 161 and requires the "2c" version of authentication, its read-only community is public.

The SNMP MIB can be downloaded from section Management -> Remote Management of the bero*fix GUI.
Since the information provided by a bero*fix can change from one AppFS-version to another,
it is advisable to use the MIB provided by the currently used AppFS and update it after each AppFS-update.


Install the bero*fix MIB in net-snmp

To find the proper locations of the file snmp.conf and the directories where MIBs can be stored, the tool net-snmp-config can be used:

net-snmp-config --default-mibdirs
net-snmp-config --snmpconfpath

The file BEROFIX-MIB.txt must be copied in one of the paths listed by "--default-mibdirs"

If it not exists, create a file named snmp.conf in one of the directories listed by "--snmpconfpath" and add this line to it:

mibs +BEROFIX-MIB

To check that the MIB has been imported correctly, use the tool snmpwalk:

snmpwalk -v 2c -c public <IP-address of berofix> .iso
