Arp Configuration - Huawei AR150 series Configuration Manual

Configuration Guide - IP Service
About This Chapter
ARP can map an IP address to a MAC address and implements transmission of Ethernet frames.
1.1 ARP Overview
ARP dynamically maps Layer 3 IP addresses to Layer 2 MAC addresses. An Ethernet device
must support ARP.
1.2 ARP Features Supported by the AR150/200
This section describes ARP Features supported by the AR150/200.
1.3 Configuring Static ARP
Static ARP entries record fixed mappings between IP addresses and MAC addresses. They are
configured manually by network administrators.
1.4 Optimizing Dynamic ARP
If dynamic ARP is configured, the system resolves an IP address into an Ethernet MAC address.
Dynamic ARP entries are maintained dynamically by the ARP protocol. You can adjust
parameters of dynamic ARP entries such as the number of ARP probes and the aging time of
dynamic ARP entries to optimize forwarding performance of the AR150/200.
1.5 Configuring Routed Proxy ARP
Routed proxy ARP implements communication between devices on the same network segment
but on different physical networks.
1.6 Configuring Intra-VLAN Proxy ARP
Intra-VLAN proxy ARP enables hosts that are isolated at Layer 2 in a VLAN to communicate
with each other.
1.7 Configuring Inter-VLAN Proxy ARP
Inter-VLAN proxy ARP enables hosts in different sub-VLANs of a super-VLAN to
communicate with each other.
1.8 Configuring ARP-Ping IP
ARP-Ping IP checks whether an IP address on a LAN is in use by sending ARP packets.
1.9 Configuring ARP-Ping MAC
ARP-Ping MAC checks whether a MAC address on a LAN is in use by sending Internet Control
Management Protocol (ICMP) packets.
