Using Templates to Configure ACL TCAM Region Sizes

You can use create and apply custom templates to configure ACL TCAM region sizes.
For all Cisco Nexus 9200, 9300, and 9500 Series switches and the Cisco Nexus 3164Q, 31128PQ, 3232C,
and 3264Q switches, you can use this procedure or the
to configure ACL TCAM region sizes. However, NFE2-enabled devices (such as the X9432C-S 100G line
card and the C9508-FM-S fabric module) do not support the hardware access-list tcam region command
and must use a template to configure the ACL TCAM region size.
Note Once you apply a TCAM template, the hardware access-list tcam region command will not work. You must
uncommit the template in order to use the command.
Note For information on configuring QoS TCAM carving, see the Cisco Nexus 9000 Series NX-OS Quality of
Service Configuration Guide.
