Thanks for explanation.

Is there any chance to put this kind of information in nav docs? Two interesting things were explained in this thread.

I'm here to help with this if you want... I'm work in a University in Brazil -> UFSC and I can help the project feeding the knowledge base whenever possible.

Normally, when the LLDP-MIB is properly implemented, one should be able
to retrieve a timestamp (lldpStatsRemTablesLastChangeTime) that
represents the sysUpTime of the system when the lldpRemTable was last
updated.

NAV retrieves this timestamp before polling the lldpRemTable, so it can
detect whether there have been any changes that warrant a new poll. If
things are pretty static, this means NAV can avoid spending time on
polling the device for the full lldpRemTable unnecessarily.

This warning message is NAV telling you that it couldn't retrieve a
timestamp from this device, so it will poll the full lldpRemTable every
time it checks for updates.
