The display arp error packet command displays information about the latest 10 Address Resolution Protocol (ARP) error packets received on the specified interface board. If no interface board is specified, information about the latest 10 ARP error packets received on the main control board is displayed.
When the device cannot learn ARP entries, you can run this command to check whether the main control board or specified interface board has received error ARP packets. Then, you can analyze and locate the fault based on the information about the error ARP packets.
# Check whether the interface board in slot 1 has received ARP error packets.
