We've designed and implemented a new SNMP polling algorithm that helps to greatly decrease device synchronization time.
When adding an SNMP device account, this algorithm quickly detects MIBs the device supports and allows operator to select ones to be monitored. After that, only OIDs defined in the selected MIBs will be polled.
However, if you want to obtain all SNMP variables provided by device, you always fall back to original SNMP walk method.
