**Table 1** Description of the **display arp ip-conflict track** command output
Item	Description
Conflict type	IP address conflict type: Local IP conflict occurs between a local device and another device. Remote IP conflict occurs between devices and users attached to a local access device.
IP address	Conflicting IP addresses. In a Local-ce IP conflict, this field indicates a CE IP address.
System time	System time when an IP conflict occurred.
Conflict count	Total number of the IP conflict times. The field is displayed as 0 if the ARP entry corresponding to the IP address expires or is deleted.
Suppress count	Number of the suppressed IP conflicts. The field is displayed as 0 if the ARP entry corresponding to the IP address expires or is deleted.
Old interface	Interface recorded in the ARP entry of the IP address. In a Local IP conflict or Local-ce IP conflict, this field is displayed as Local interface, indicating the interface in the ARP entry of the IP address.
Local interface	Interface in the ARP entry of the conflicting IP address. In a Remote IP conflict, this field is displayed as Old interface, indicating the interface in the ARP entry of this IP address before the conflict.
Receive interface	Inbound interface of the second ARP packet with the IP address.
Old VLAN/CEVLAN	VLAN and CEVLAN recorded in the ARP entry of the IP address. This field is displayed only in a Remote IP conflict.
Receive VLAN/CEVLAN	VLAN and CEVLAN configured on the inbound interface of the second ARP packet with the IP address.
Old MAC	Source MAC address recorded in the ARP entry of the IP address. This field is displayed only in a Remote IP conflict.
Local MAC	The value of local-ce mac configured on an interface. If local-ce mac is not configured, this field value is 0000-0000-0000. This field is displayed only in a Local-ce IP conflict.
Receive MAC	Source MAC address of the second ARP packet with the IP address.
