Overview

IP filters are used to manage traffic and, in some cases, to provide security. Each filter set includes match conditions (a list of filter records defining the match criteria) and actions (forward, drop, prioritize, mirror, modify DS field, modify IEEE 802.1p priority, or prevent incoming TCP connections) to be performed when a match condition is satisfied.

However certain configurations that require a large number of IP filters are known to block the processing of LED information. Therefore, the CPU Utilization LED display may not be updated when the CPU is at 100% utilization.
