Enabling ARP logging
This feature enables a device to log ARP events when ARP cannot resolve IP addresses correctly. The device can log the following ARP events:
On a proxy ARP-disabled interface, the target IP address of a received ARP packet is not the IP address of the receiving interface.
The sender IP address of a received ARP reply conflicts with the IP address of the receiving interface.
The device sends ARP log messages to the information center. You can use the info-center source command to specify the log output rules for the information center. For more information about information center, see Network Management and Monitoring Configuration Guide.
