What is pgExternalPortReceivedOversizedPackets?
This 64-bit counter tracks packets received on the external port that exceed the expected maximum frame size. A growing count can indicate misconfigured jumbo frames upstream or a crafted-packet probe against the device. For example, an admin seeing this counter spike during a suspected attack would check whether an upstream router's MTU setting was recently changed before assuming malicious intent.
