Quidway S6500 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.
2.2 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
Enable/Disable ARP the checking function of ARP entry
2.2.1 Manually Add/Delete Static ARP Mapping Entries
Perform the following configuration in System view.
Table 2-1 Manually add/delete static ARP mapping Entries
Manually add a static ARP mapping
entry
Manually delete a static ARP mapping
entry
By default, the ARP mapping table is empty and the address mapping is obtained
through dynamic ARP.
Note that:
Static ARP map entry will be always valid as long as Ethernet switch works
normally. But if you modify or delete VLAN interfaces, delete VLANs or delete
ports from VLANs to make ARP invalid, the ARP mapping entry will be
automatically 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.
The aggregation port or port with LACP enabled cannot be set as the egress port
of static ARP.
