Parameter
ip-address: IP address of the ARP mapping entry.
mac-address: MAC address of the ARP mapping entry, whose format is H-H-H ( H
indicates a hexadecimal number).
vlan-id: VLAN to which the static ARP entry belongs, in the range of 1 to 4094.
interface-type interface-number: The type and number of the port to which the static
ARP entry belongs.
vpn-instance vpn-instance-name: VPN instance name in MPLS VPN.
Description
Use the arp static command to configure the static ARP mapping entries in an ARP
mapping table.
Use the undo arp static command to delete a static ARP mapping entry from the ARP
table.
By default, the mapping table of the system ARP is empty and the switch can obtain its
address mapping by means of dynamic ARP.
The arp static command can be used to configure auto filling of ARP entries. When
configuring an ARP entry, if you input on the IP address, the switch will automatically
set the MAC address to 0. Such a mapping entry is auto-fill ARP mapping entry. When
an auto-fill ARP entry is resolved, the switch can automatically fill it with the learned
MAC address as the MAC address corresponding to the IP address in this mapping
entry.
Note that:
When the switch works normally, its static ARP mapping entries remain valid and
work unless you perform operations that invalidate ARP entries, such as changing
or removing VLAN interfaces, removing a VLAN, or removing an port from a VLAN.
These operations will cause the corresponding ARP mapping entries to be
automatically removed.
The argument vlan-id must be the ID of an existing VLAN, and the Ethernet port
specified behind this parameter must belong to the VLAN.
The argument vpn-instance-name must be the VPN-instance name of an existing
MPLS VPN.
