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.
