1-3interface-number: Number of the port to which the static ARP entry belongs.DescriptionUse the arp static command to create a static ARP entry.Use the undo arp command to remove an ARP entry.By default, the system ARP mapping table is empty and the address mapping entries are obtained byARP dynamically.Note that:z Static ARP entries are valid as long as the Ethernet switch operates normally. But some operations,such as removing a VLAN, or removing a port from a VLAN, will make the corresponding ARPentries invalid and therefore removed automatically.z As for the arp static command, the value of the vlan-id argument must be the ID of an existingVLAN, and the port identified by the interface-type and interface-number arguments must belong tothe VLAN.z Currently, static ARP entries cannot be configured on the ports of an aggregation group.Related commands: reset arp, display arp.Examples# Create a static ARP mapping entry, with the IP address of 202.38.10.2, the MAC address of000f-e20f-0000.
