2.1 ARP Configuration
2.1.1 Introduction to ARP
Address resolution protocol (ARP) is mainly used for resolution from IP address to an
Ethernet MAC address. Normally, ARP runs dynamically and automatically resolves an
IP address to an Ethernet MAC address, that is, no operation from the administrator is
needed.
In Comware implementation, the system creates or updates ARP table entries when
the received ARP packet meets any of the following criteria:
z
The source IP address of the ARP packet is in the same network segment as the
IP address of the inbound interface, and it is not a broadcast address; the
destination IP address is the IP address of this interface.
z
The source IP address of the ARP packet is in the same segment as the IP
address of the inbound interface, and it is not a broadcast address; the destination
IP address is the VRRP virtual IP address of this interface.
z
The destination IP address of the ARP packet belongs to the configured NAT
address pool on the inbound interface.
If the source IP address of the received ARP packet already has a corresponding
dynamic entry in the ARP table of the inbound interface, the ARP table entry will be
updated. If the source IP address of the received ARP packet already has a
corresponding static entry in the ARP table of the inbound interface, the ARP table
entry will not be updated.
To enable the proxy ARP function or to filter some illegal IP addresses (such as binding
these illegal addresses to a nonexistent MAC address), you need to configure a
corresponding entry in the static ARP table.
2.1.2 Configuring Static ARP
The static ARP configuration includes manually adding and deleting static ARP
mapping entry.
Perform the following configuration in system view.
