Information About TCAM Carving
The Ternary Content-Addressable Memory (TCAM) carving feature uses a template-based approach that enables you to modify the default region sizes of the TCAM. When the switch boots up, you see this default template, unless you have configured any other template. This table lists the types and sizes of various regions in a template.
