SNMP can be helpful for managing large networks, and some router manufacturers are including SNMP functions in their routers, most notably Linksys.  You’ll need to use some sort of SNMP utility to capture and read the generated messages, however.  Linux and Unix users won’t have much of a problem finding SNMP Trap utilities, but Windows and MacOS users may need more help.

SNMP Websites

SimpleWeb.org

SimpleWeb provides links and information on network management, including software, RFCs and tutorials. The focus is on SNMP and Internet management, but people interested in other management technologies will also find interesting information.
Maintained by the Telematics Systems and Services management group (TSS) of the University of Twente (the Netherlands), in collaboration with Jürgen Schönwälder of the TU Braunschweig (Germany).

Software section has a nice Search tool, that lets you search by OS and whether something is free.


SNMPLink.org

Another SNMP links site, put up by Pierrick Simier.  Nice to look at, but Search tool is not as helpful as SimpleWeb’s.
