Parameters

Parameter	Description	Value
slot slot-id	Specifies the slot ID of a board. If this parameter is specified, the command displays ARP packet statistics of this board. If this parameter is not specified, the command displays ARP packet statistics of all boards.	In VS mode, this parameter is supported only by the admin VS.
interface interface-type interface-number	Displays the ARP packets sent and received by a specified a Layer 3 interface.	-

Usage Guidelines

Usage Scenario

To locate and rectify ARP faults, you need to view statistics about ARP packets sent and received by the device.

Precautions

Run the display arp packet statistics interface command to view the interfaces that send and receive ARP packets and the statistics about the ARP packets.

The displayed statistics on an interface are the accumulative statistics about ARP packets sent and received by this interface.
For example, if an interface sends a gratuitous ARP reply packet, the interface records the packet in the statistics about ARP reply packets as well as in the statistics about gratuitous ARP packets.

Example

The actual command output varies according to the device. The command output here is only an example.
