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
bero*fix Parameters
SNMP provides the tools snmpwalk, snmpget and snmptable to retrieve values exported by bero*fix via SNMP.
Walk over the complete tree
To see all data exported by bero*fix, use snmpwalk with the following parameters. Keep in mind to append '.iso', without it you'll only see an error-message.
snmpwalk -v 2c -c public <IP-address of berofix> .iso
