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.
