This can happen for several reasons. Someone on the network is ARP poisoning hosts.

This feature enables a device to log ARP events when ARP cannot resolve IP addresses correctly. The log information helps administrators locate and solve problems. 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.

2007年5月4日 · Dynamic ARP Inspection (DAI) is a security feature that validates Address Resolution Protocol (ARP) packets in a network. DAI allows a network administrator to intercept, log, and discard ARP packets with invalid MAC address to IP address bindings. This capability protects the network from certain “man-in-the-middle” attacks.

Arpalert uses ARP protocol monitoring to prevent unauthorized connections on the local network. If an illegal connection is detected, a program or script could be launched, which could be used to send an alert message, for example. Specify the config …

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 one of the following IP addresses:

All Cisco routers and switches support logging functionality. Logging capabilities are also available for specific features and protocols. For example, logging can be enabled for BGP session state changes or OSPF adjacency state changes. Table 2-3 lists the various logging levels that can be configured. Table 2-3 Logging Levels.
