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