This allows youto interrogate it using host tools of your choice. It supports MIBsas documented above, so eg. <BCLASS="COMMAND">snmpwalk<TTCLASS="REPLACEABLE"><I><hostname></I></TT> public dot3</B> underLinux/UNIX should have the desired effect.</P><P>For serious testing, you should increase the length of timethe test runs by setting CYGNUM_SNMPAGENT_TESTS_ITERATIONSto something big (e.g., 999999). Build the test(<BCLASS="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 makethe stats change) and some for interrogating the snmpd.
