Applicable Environment
Before assigning an IP address to a device, you need to use the arp-ping ip command to check
whether this IP address is used by another device on a LAN.

Run the display arp [ all ] command to check all the ARP mapping tables, including static
and dynamic ARP entries.
Run the display arp dynamic [ | { begin | exclude | include } regular-expression ]
command to check the dynamic ARP mapping table.
Run the display arp interface interface-type interface-number [ vid vlan-id ] [ | { begin
| exclude | include } regular-expression ] command to check the ARP mapping table on a
specified interface.
Run the display arp network net-number net-mask [ dynamic | static ] [ | { begin |
exclude | include } regular-expression ] command to check the dynamic ARP mapping
table on a specified network segment.
Run the display arp statistics command to check the statistics on ARP entries, including
the total number of ARP entries, the number of dynamic ARP entries, the number of static
ARP entries, and the number of ARP entries configured on the interface.
Run the display arp vpn-instance vpn-instance-name [ dynamic | static ] [ | { begin |
