Chapter 6 – SNMP
FS3 Simple Network Management Protocol
SNMP is defined as a “simple network management protocol” and was specified
as a component of the internet protocol suite by the Internet Engineering
Task Force (IETF). The FS3 can act as a network element that issues SNMP trap
messages signaling a detected alarm condition or other system condition. A
device’s trap messages are defined in an MIB (Management Information Base)
file. The trap messages are sent to a server-based external NMS destination.
For example, the FS3 could send a trap message if one of its redundant power
supplies becomes unplugged. A client software agent that communicates with
the NMS might then get a message telling the operator what has happened.
The FS3 must be configured for SNMP messaging. By default SNMP is disabled
on the FS3. Besides activating SNMP, trap destinations must also be defined with
fixed IP addresses.
When SNMP is enabled, one or more of these alarms may be sent by the FS3 to
the client network management system (NMS) as a trap message:
• PowerSupplyAlarm (PS1 Alarm)
• PowerSupply2Alarm (PS2 Alarm)
• ReferenceAlarm (Ref Video Alarm)
• VidReferenceAlarm (VidRef Video Alarm)
• VidFormatAlarm (Vid1 Format Alarm)
• OverTemperatureAlarm (FS3 Over Temperature Alarm)
SNMP Configuration
FS3 SNMP configuration can be accomplished using the front panel or with the
web browser computer interface (if Remote Control is enabled).
Front Panel Screens
The FS3 front panel screens for SNMP are accessible through the CONFIG button.
The direct SNMP configuration screens are:
• 4.0 SNMP Enable
• 4.1 SNMP Trap Destination 1
• 4.2 SNMP Trap Port 1
• 4.3 SNMP Trap Destination 2
• 4.4 SNMP Trap Port 2
These SNMP direct configuration parameters are described later in this chapter.
In addition, the following front panel CONFIG screens can affect SNMP alarm
messaging:
• 5 Power Supply Alarm
• 6 Video Format Alarm
• 7 Reference Alarm
