COMMAND USAGE
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.
PARAMETERS
These parameters are displayed:
◆ Total Policy Control Entries – The number policy control entries in
use.
◆ Free Policy Control Entries – The number of policy control entries
available for use.
◆ Entries Used by System – The number of policy control entries used
by the operating system.
