Viewing CAM Usage
View the amount of CAM space available, used, and remaining in each partition (including IPv4Flow and Layer
2 ACL sub- partitions) using the show cam-usage command in EXEC Privilege mode
Display Layer 2, Layer 3, ACL, or all CAM usage statistics.
EXCE Privilege mode
show cam usage [acl | router | switch]
The following sample output shows the consumption of CAM blocks for Layer 2 and Layer 3 ACLs, in addition
to other processes that use CAM space:
