5.13.1 The SNMP traps
The previous table defines which specifics traps are sent by the SNMP agent to the network manager.
For instance, if the command “BUCPOWER ON/OFF” is issued a message is recorded to the LOG file
and an SNMP trap specific (6,2) or (6,3) is sent to the configured destination network manager.
5.13.2 Using the log file

RAM file of 16k keeping the most recent alarms and events;
