ARP Attribute

You can set parameters of dynamic ARP entries, such as the number of aging detection times and aging time.

You can set ARP parameters to use ARP entries flexibly.

Choose Service Management > ARP > ARP Attribute in the navigation tree to open the ARP Attribute page.

Table 1 describes the parameters on the ARP Attribute page.

**Table 1** ARP Attribute
Parameter	Description
VLANIF	Indicates the name of a VLANIF interface.
Probe count	Indicates the number of aging detection times. When a dynamic ARP entry expires, the switch sends aging detection packets to the corresponding host. If the host does not respond when the specified number of detection times is reached, the ARP entry is deleted. A proper number of aging detection times can reduce address resolution errors caused by slow update of ARP entries. NOTE: If this parameter is set to 0, the switch deletes expired ARP entries directly.
Aging time	Indicates the aging time of ARP entries. The default value is 1200 seconds.
