CMU SNMP PackageCMU has written a decent SNMP package that includes a library, a set of UNIX command line utilities, and Tcl and Tk interfaces. Free download and more information can be found at its web page.
One of the most useful command-line utilities in this package
is snmpnetstat, which sends a series of SNMP Get requests
to inquire about a remote host's network status, and presents
this information in a form similar to that used by netstat
to display local network information.
The default display shows active Internet-domain connections.
Options are available to display a list of network interfaces,
or to display the remote routing table. Obviously, a working
network connection is required to make use of this program,
a quick and easily understood SNMP management tool.
