+>"snmpping" in the SNMP agent package runs the ping test from
+the TCPIP package, with the snmpd running also. This allows you
+to interrogate it using host tools of your choice. It supports MIBs
+as documented above, so eg. <B
+CLASS="COMMAND"
+>snmpwalk
+<TT
+CLASS="REPLACEABLE"
+><I
+><hostname></I
+></TT
+> public dot3</B
+> under
+Linux/UNIX should have the desired effect.</P
+><P
+>For serious testing, you should increase the length of time
+the test runs by setting CYGNUM_SNMPAGENT_TESTS_ITERATIONS
+to something big (e.g., 999999). Build the test
+(<B
+CLASS="COMMAND"
+>make -C net/snmp/agent/current tests</B
+>)
+and run it on the target.</P
+><P
+>Then start several jobs, some for pinging the board (to make
+the stats change) and some for interrogating the snmpd. Set $IP
+to whatever IP address the board has:</P
