Galaxy Pulsar Edge Power System Controller
Issue 3 October 2011 199
SNMP Operations
Interactions between the SNMP Host and the SNMP Agent can be any of four different types of
commands: Reads, Writes, Traversal operations, and Traps. SNMP utilizes six operations to
respond to the various SNMP Hosts: Get, GetNext, GetBulk, Set, Trap, and Inform. The Pulsar
Edge implements the Get, GetNext, Set, and Trap operations.
Get - Allows the SNMP Host to retrieve a value from the SNMP Agent.
GetNext - Allows the SNMP Host to retrieve the next value in sequence from a table or list of
variables in the SNMP Agent.
Set - Allows the SNMP Host to set a value within the SNMP Agent.
Trap - Used by the SNMP Agent (the power system controller) to asynchronously inform the
SNMP Host of an event such as an alarm notification. Unlike the other operations, the trap does
not require a response from the host. The SNMP Agent must be configured with appropriate
addresses of the SNMP Host.
SNMP Configuration
SNMP functionality is always available. No enabling or disabling of the feature is
required. Appropriate trap destinations and assignments of specific alarms must be
configured for SNMP to properly send out Traps. Users can configure these SNMP
parameters from the browser interface. They may also be configured from a Telnet
command line interface.
Configuration of the IP addresses for Trap destinations is performed under the “Network”
link under the main configuration “Settings” tab. The Pulsar Edge supports up to four
different destinations for SNMP messages. Each destination (1 through 4) is configured
with an IP address. The sample screen for this configuration follows.
