As per Cisco Documentation, this warning is informing you that you are maxing the TCAM resource allocation for a specific feature. You should be able to see your utilisation/allocation per feature via:

show system internal access-list resource utilization

You may also be able to perform TCAM carving to reallocate resources if required.

  • the only thing is near the threshold is "N3K SUP 125 3 97.65" other things has at leat %70 free space – Blackmetal Oct 22 '20 at 7:29
  • @Blackmetal, that means you need to change the allocation of your TCAM, reducing the TCAM allocated to the things with little usage, and giving more to what is full. – Ron Maupin Oct 22 '20 at 11:30
  • i can not find which tcam module should i adjust, because everything seems right, can you guide me more? – Blackmetal Oct 23 '20 at 14:15
