ip-mac conflict drop-only
| conflict | Action performed when a conflict exists between the IP address and MAC address. This option is enabled by default. | 
| drop-only | Drops a packet without logging | 
ip-mac conflict [log-and-drop|log-only] log-level [<0-7>|alerts|critical|debug| emergencies|errors|informational|notifications|warnings]
| conflict | Action performed when a conflict exists between the IP address and MAC address. This option is enabled by default. | 
| log-and-drop | Logs the event and drops the packet. This is the default setting. | 
| log-only | Logs the event only, the packet is not dropped | 
| log-level | Configures the log level | 
| <0-7> | Sets the numeric logging level | 
| alerts | Numerical severity 1. Indicates a condition where immediate action is required | 
| critical | Numerical severity 2. Indicates a critical condition | 
| debugging | Numerical severity 7. Debugging messages | 
| emergencies | Numerical severity 0. System is unusable | 
| errors | Numerical severity 3. Indicates an error condition | 
| informational | Numerical severity 6. Indicates a informational condition | 
| notification | Numerical severity 5. Indicates a normal but significant condition | 
| warnings | Numerical severity 4. Indicates a warning condition. This is the default setting. | 
ip-mac routing conflict drop-only
| routing | Enables IPMAC routing conflict detection. This is also known as a Hole-196 attack in the network. This feature helps to detect if the client is sending routed packets to the correct router-mac-address. | 
| conflict | Defines the action performed when a routing table conflict is detected. This option is enabled by default. | 
| drop-only | Drops a packet without logging |
