Configuring The Arp Aging Timer For Dynamic Arp Entries; Enabling The Arp Entry Checking Function - Huawei Quidway S3900 Series Operation Manual

Operation Manual – ARP
Quidway S3900 Series Ethernet Switches-Release 1510
Caution:
Static ARP mapping entries are valid as long as the Ethernet switch operates. But
the following operations result in ARP entries being removed: changing/removing
a VLAN interface, removing a VLAN, or removing a port from a VLAN.
As for the arp static command, the value of the vlan-id argument must be the ID of
an existing VLAN, and the port identified by the interface-type and
interface-number arguments must belong to the VLAN.
Currently, the system does not support static ARP mapping entry at aggregation
port.
