Description: This object provides total dropped invalid packets number.
What is hpnicfURPFDroppedPacket?
This Counter64 counts the total number of packets dropped because they failed the URPF check, meaning their source address didn't match a valid reverse path in the routing table. Admins watch this counter to detect spoofed-source traffic or misconfigured asymmetric routing being filtered by URPF. A sudden spike from near-zero to thousands of drops per minute would suggest a spoofing attempt or a routing asymmetry issue on that VLAN interface.
