What does it do and how does it work?

Stormfinder is a little utility that requests non-unicast packet statistics from

all interfaces of a network device using SNMP. After requesting the number of

incoming NU-packets (i.e. broadcasts and multicasts) it does so again after 10

seconds and calculates the difference. Excessively high numbers of NU-packets in

this time interval indicate a network loop which should be investigated. In the

first column of the table, the OID is shown where the number after the last dot

is the interface number.

Simply enter the IP address and SNMP community of your device into the corresponding

fields and click on "Check Now". After ten seconds or so you will see the results

in the "Delta"-column of the table. Check for excessive NU-packets.

Please note!

SNMP is using UDP and a loop in the network is causing many packets to be delayed

or to get lost. Therefore, under certain circumstances this software may not yield

the desired results.
