I am trying to use SNMP4SDN to discover physical switch using s4sTopoDiscover but I am unable to do so. The reason being I am facing issue updating SwitchDB.txt contains MAC,IP,SNMPCommunity,CLIUsername,CLI_Password. The SNMP Community value is empty for SNMPv2 and SNMPv3 (I believe it is valid for SNMPv1 or SNMPv2C)? Also, the appropriate files for compilation of the plugin and tests are updated and the Jar file copied to the directory.
I tried using an empty string for community and valid Username, Password values but I do not see the Switch discovered either in the OSGi console or ODL GUI. Any ideas what can help to discover the topology for switch already up?
