SNMP (Simple Network Management Protocol) is an Internet-standard protocol for managing devices
connected to IP networks. SNMP is widely used in network management systems to monitor
networked devices for conditions that warrant administrative attention.
An SNMP-managed network consists of three key components:
Managed device (allows unidirectional or bidirectional access to node-specific information)
Agent — the software which runs on managed devices
Network Management Station (NMS) — the software which runs on the manager
This manual documents trap (notification) messages that keep the user informed of events that
occur, in real time, on each agent on the managed device (Matrix Switch). It contains sections for
SFP Generated Traps, Switch Generated Traps and Standard Traps, as well as Regulatory &
Safety Requirements and Thinklogical Support.
Note and Warning Symbols
In Sections 4 and 5 of this manual you will notice certain symbols that bring your attention to important
information. These are Notes and Warnings. Examples are shown below.
Note: Important Notes appear in blue text preceded by a yellow exclamation point symbol, as
shown here.
A note is meant to call the reader’s attention to helpful or important information at a point in the text that is
relevant to the subject being discussed.
Warning! All Warnings appear in red text, followed by blue text, and preceded by a red stop
sign, as shown here.
A warning is meant to call the reader’s attention to critical information at a point in the text that is relevant to
the subject being discussed.
