20 Setting Up the SNMP
Server
The SNMP server is an optional software module that allows the SMP Gateway to export statistics
using the SNMP standard (Simple Network Management Protocol).
The SMP Gateway’s SNMP agent publishes and supports both standard MIBs (management
information bases) that are supported by the Windows CE operating system and custom MIBs that
are supported by the SMP Gateway application. The agent supports extensive “reading”
capabilities as well as limited “writing” and “trap” capabilities.
20.1 SNMP Traps
SNMP traps are messages that are automatically sent to selected SNMP clients when specific,
unusual events occur. They are the text equivalent of alarms. Traps are automatically sent to
listening SNMP clients whenever:
the SMP Gateway restarts;
a communications link used by a master or slave protocol instance fails for more than 60
consecutive seconds (these traps are called link down traps);
a communications link used by a master or slave protocol instance becomes active (these traps
are called link up traps).
In order to send traps, the SMP Gateway needs to know the IP addresses of the SNMP clients that
are listening on the network. You can enter a maximum of 32 SNMP client IP addresses using the
SMP Gateway’s SNMP Manager.
20.2 Configuring the SNMP Server
