"Layer 3 Job Statistics
Consult these objects about endpoints (IP addresses) and their mapping to corresponding MAC addresses to find what the device whose IP address UDT cannot see is returning for the IP-MAC.
ipNetToMediaTable
ipNetToPhysicalTable
Note: If the device does not support those objects UDT cannot get any layer3 information."
UDT Compatibility Checker shows that some switches on our network are only successful polling ipNetToMediaTable, but fail on ipNetToPhysicalTable.
Running an SNMP get table on the OID for ipNetToMediaTable on these switches does produce results that include MAC addresses and IP addresses.
Should I expect to see Layer 3 results in UDT, or does UDT require both ipNetToMediaTable and ipNetToPhysicalTable?
