Parameters

all: Displays all ARP entries.

dynamic: Displays dynamic ARP entries.

multiport: Displays multiport ARP entries.

static: Displays static ARP entries.

slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command displays ARP entries for the active MPU.

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. If you do not specify a card, this command displays ARP entries for the global active MPU.

vlan vlan-id: Specifies a VLAN by its VLAN ID. The VLAN ID is in the range of 1 to 4094.

interface interface-type interface-number: Specifies an interface by its type and number. If you do not specify an interface, this command displays ARP entries for all interfaces.

count: Displays the number of ARP entries.

verbose: Displays detailed information about ARP entries.

Usage guidelines

This command displays information about ARP entries, including the IP address, MAC address, VLAN ID, output interface, entry type, and aging timer.

Table 1: Command output

Field	Description
IP Address	IP address in an ARP entry.
MAC Address	MAC address in an ARP entry.
VID	ID of the VLAN or index of the VSI to which the ARP entry belongs. This field displays N/A in either of the following situations: The ARP entry is an unresolved short static ARP entry. The output interface of the ARP entry does not belong to the VLAN or VSI.
Interface/Link ID	Output interface or the link ID in an ARP entry. This field displays N/A in either of the following situations: The ARP entry is an unresolved short static ARP entry. The ARP entry is a multiport ARP entry and has no output interface information.To obtain the output interface information of the multiport ARP entry, look up the MAC address table according to the MAC address in the ARP entry.
Aging	Aging time for an ARP entry in seconds. For a static ARP entry, this field always displays N/A. The static ARP entry never ages out unless you delete it manually. For a dynamic ARP entry, this field displays N/A if the aging time is unknown.
Type	ARP entry type: D—Dynamic. S—Static. O—OpenFlow. R—Rule. M—Multiport. I—Invalid.
Nickname	Nickname of the ARP entry. The nickname is a string of four hexadecimal numbers, for example, 012a. For more information about the nickname, see TRILL Configuration Guide.
VPN Instance	Name of VPN instance. If no VPN instance is configured for the ARP entry, this field displays [No Vrf].
VXLAN ID	ID of the VXLAN to which the ARP entry belongs. VXLAN ID is also called VNI. If the ARP entry does not belong to any VXLAN, this field displays N/A.
VSI Name	Name of the VSI to which the ARP entry belongs. If the ARP entry does not belong to any VSI, this field displays N/A.
VSI Interface	Name of the gateway interface of the VSI. If no gateway interface is specified for the VSI, this field displays N/A.
Total number of entries	Number of ARP entries.
