Impact on the System

Some ARP request and reply packets will be incorrectly discarded.

Possible Causes

The arp learning strict { force-enable | force-disable | trust }, or arp learning strict command was run. As a result, the device discarded the ARP reply packet that is not in response to the ARP request packets sent by itself. With strict ARP learning, the device only learns the ARP reply packets in response to the ARP request packets sent by itself.

Procedure

  • The trap is informational only, and no action is required.
