show access-list
tcam-utilization
This command shows utilization parameters for TCAM (Ternary Content
Addressable Memory), including the number policy control entries in use, and the
number of free entries.
Command Mode
Privileged Exec
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.
