Arp Configuration; Adding A Static Arp Mapping Entry Manually - Huawei Quidway S3900 Series Operation Manual

Operation Manual – ARP
Quidway S3900 Series Ethernet Switches-Release 1510
When the gratuitous ARP packet learning function is enabled on a switch and the
switch receives a gratuitous ARP packet, the switch updates the existing ARP entry
(contained in the cache of the switch) that matches the received gratuitous ARP
packet using the hardware address of the sender carried in the gratuitous ARP packet.
A switch operates like this whenever it receives a gratuitous ARP packet.

1.2 ARP Configuration

ARP entries in an S3900 series Ethernet switch can either be static entries or dynamic
