Dantel WebMon Walking issue

The crazy thing is I spoke with the manufacturer because I have this plugin working with a slightly older version of their firmware. They stated the newer firmware they did make some snmp changes to make the snmp more compliant with snmp standards… but the new version is the one that doesn’t work. just confusing that the older “non-compliant” version works but the newer snmp compliant version doesn’t work which is why I thought maybe something was wrong with my coding.

appreciate the help
