Description (partial)

Symptom:
N1K allows non-existence ACL to be configured/used:
n1k# sh port-profile name dummy1
port-profile dummy1
  description: 
  type: vethernet
  status: enabled
  capability l3control: no
  pinning control-vlan: -
  pinning packet-vlan: -
  system vlans: none
  port-group: dummy1
  max ports: 256
  inherit: 
  config attributes:
    switchport mode access
    switchport access vlan 1108
    no shutdown
  evaluated config attributes:
    switchport mode access
    switchport access vlan 1108
    no shutdown
  assigned interfaces:
    Vethernet26
n1k# 
n1k# sh ip access-lists dummy1
n1k# 
n1k# conf t
n1k(config)# port-profile dummy1
n1k(config-port-prof)# ip port access-group dummy1 ?
  in   Inbound packets
  out  Outbound packets

n1k(config-port-prof)# ip port access-group dummy1 in
n1k(config-port-prof)# 
n1k(config-port-prof)# 
n1k(config-port-prof)# 
n1k(config-port-prof)# exit
n1k(config)# int veth 26
n1k(config-if)# ip port access-group dummy1 in

The system should reject reference to non-existence ACL in 'ip port access-group' config, allowing reference to non-existence ACL would result in packet drop because of implicit deny all in ACL.

Conditions:
Reference to non-existence ACL.
