Operation Manual - Network Protocol
Quidway S3000-EI Series Ethernet Switches
Normally, dynamic ARP executes and automatically searches for the resolution from
the IP address to the Ethernet MAC address without the administrator.

1.2 Configure ARP

The ARP mapping table can be maintained dynamically or manually. Usually, the
manually configured mapping from the IP addresses to the MAC addresses is known
as static ARP. The user can display, add or delete the entries in the ARP mapping table
through relevant manual maintenance commands.
The static ARP configuration includes:

Manually Add/delete static ARP Mapping Entries

Configure the dynamic ARP aging timer

Enabling/Disabling ARP the Checking Function of ARP Entry

1.2.1 Manually Add/Delete Static ARP Mapping Entries
Perform the following configuration in System view.
Table 1-1 Manually add/delete static ARP mapping Entries
Manually add a static ARP mapping
entry
Manually delete a static ARP mapping
entry
Static ARP map entry will be always valid as long as Ethernet switch works normally.
But if the VLAN corresponding ARP mapping entry is deleted, the ARP mapping entry
will be also deleted. The valid period of dynamic ARP map entries will last only 20
minutes by default.
The parameter vlan-id must be the ID of a VLAN that has been created by the user, and
the Ethernet port specified behind this parameter must belong to the VLAN.
By default, the ARP mapping table is empty and the address mapping is obtained
through dynamic ARP.
1.2.2 Configure the Dynamic ARP Aging Timer
For purpose of flexible configuration, the system provides the following commands to
assign dynamic ARP aging period. When the system learns a dynamic ARP entry, its
aging period is based on the current value configured.
Perform the following configuration in system view.
