Symptom

On a Nexus 93180YC-EX that has a TCAM template configured, the following error is seen when a PACL is applied to an interface: "ERROR: TCAM region is not configured. Please configure TCAM region and retry the command." However, the TCAM hardware/software outputs indicate that the ing-ifacl (PACL) region is configured and has space available: switch# show hardware access-list tcam region ... Ingress PACL [ing-ifacl] size = 256 switch# show system internal access-list globals ... -------------------------------------------------------------------------------- ------ INSTANCE 0 TCAM Region Information: -------------------------------------------------------------------------------- ------ Ingress: -------- Region TID Base Size Width -------------------------------------------------------------------------------- ------ ...
