ACL Flow Meter

ACL Flow Metering Table is a per flow bandwidth control used to limit the bandwidth of the ingress traffic. When the

users create an ACL rule to filter packets, a metering rule can be created to associate with this ACL rule to limit traffic.

The step of bandwidth is 64kbps. Due to limited metering rules, not all ACL rules can associate with a metering rule.
