2. Question: Does the SDN need to change the IP address of the cluster IP before it can be authorized before it can be authorized?

Answer: Needed

3. Question: Access control and under what circumstances will be on the pending list

     (3) IP/VLAN inconsistencies

     (4) IP changes

     (5) Position change

     (6) Gateway ARP spoofing
