Quidway S3900 Series Ethernet Switches-Release 1510 Chapter 1 ARP Configuration
Huawei Technologies Proprietary
1-6
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
entries, as described in
