This counter tracks the total number of bytes (octets) received on a network interface that match a specific traffic policy rule, using a standard 32-bit counter that can count up to 4 billion. Network engineers monitor this to understand how much traffic volume is flowing through each policy rule, helping identify which policies are actually being used. For example, a value of 1,500,000 octets means roughly 1.5 megabytes of matching traffic has passed through this policy since the device was last reset.
