I have a cisco nexus n3k-c3064pq-10gx and i want to have an acl and add 270x line (they will drop my interface vlan IP address because they are public IP), I want to know can I have this acl with 270x line of acl ?

here is my TCAM output :

        30 permit ip any
        40 deny ip any

No, you don't have enough room for 270 more Ingress Router ACL entries (216 free). Here is a Cisco document explaining the different ACL types on Nexus 3000.

It looks like you're trying to reproduce the functionality of control-plane filters using older methodology. Do you know about control-plane filtering? If not, learning that concept will help you immensely. If you do already understand that it is an available feature, I suggest you read the N3K Security Configuration Guide section on Configuring Control Plane Policing and determine what traffic you do want to admit to the switch control plane.
