I am having problems with getting proxying to work on net-snmp version 5.8 that I built for Windows 10. I followed the proxy guidelines at http://net-snmp.sourceforge.net/wiki/index.php/Snmpd_proxy and set up the attached snmpd.conf file where I am using test.net-snmp.org as the "switch" in the example. Note that I am proxying the entire tree of test.net-snmp.org to 1.4 as well as using context to proxy the entire tree, using the instructions in the proxy documentation page.
Proxying the entire tree works as expected: C:\Users\markw>snmpgetnext -v 2c -c public localhost 1.4 iso.4.6.1.2.1.1.1.0 = STRING: "test.net-snmp.org" I attached proxy-entire-tree.txt for the snmpd debug output. Proxying using contexts does not work as expected: C:\Users\markw>snmpgetnext -v 2c -c cmty_myswitch localhost 1.3 Timeout: No Response from localhost. I attached proxy-using-context-mapping.txt for the snmpd debug output. Any ideas of what I'm doing wrong? Thanks. Mark.
