Policy control entries (PCEs) are used by various system functions which
rely on rule-based searches, including Access Control Lists (ACLs), IP
Source Guard filter rules, Quality of Service (QoS) processes, or traps.
For example, when binding an ACL to a port, each rule in an ACL will use
two PCEs; and when setting an IP Source Guard filter rule for a port, the
system will also use two PCEs.
