**Table 1** Description of the **display arp vpn-instance** command output
Item	Description
IP ADDRESS	IP address in an ARP entry.
MAC ADDRESS	MAC address in the ARP entry. When an IP packet triggers an ARP Miss message, the device generates a MAC address with the Incomplete flag based on the ARP Miss message.
EXPIRE(M)	Remaining lifetime of an ARP entry, in minutes.
TYPE	Type and slot ID of an ARP entry. The entry type contains 3 bits. The first bit can be any of the following: I: Interface, indicating an ARP entry of an interface. D: Dynamic, indicating a dynamic ARP entry obtained using ARP messages. S: Static, indicating an ARP entry statically configured. R: Remote, indicating the ARP entry obtained through remote backup. RD: Redirect, indicating a redirected ARP entry. The second bit can only be F, indicating that the entry is reported to the routing module, the route to this IP address is calculated, and the entry is installed to the FIB. The third bit indicates the slot ID of the interface board from which the entry is obtained.
INTERFACE	Type and number of an interface that has learned ARP entries.
VPN-INSTANCE	VPN instance name of an ARP entry.
VLAN/CEVLAN	VLAN ID of an ARP entry.
PVC	Interface on which a PVC is configured and corresponding VPI/VCI.
Redirect	Number of redirected ARP entries.
Interface	Number of ARP entries for the local interface in the ARP table.
Total	Number of ARP entries in the ARP table.
Dynamic	Number of dynamic ARP entries in the ARP table.
Static	Number of static ARP entries in the ARP table.
Remote	Number of remote backup ARP entries.
