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:
|
Interface/Link ID | Output interface or the link ID in an ARP entry. This field displays N/A in either of the following situations:
|
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:
|
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. |
