Configuring The Arp Aging Timer For Dynamic Arp Entries; Enabling The Arp Entry Checking Function - Huawei Quidway S5600 Series Operation Manual

Operation Manual – ARP
Quidway S5600 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.
