About This Chapter
ARP can map an IP address to a MAC address and implements transmission of Ethernet frames.
2.1 Overview of ARP
An Ethernet device must support ARP. ARP implements dynamic mapping between Layer 3 IP
addresses and Layer 2 MAC addresses.
2.2 Features of ARP Supported by the S9300&S9300E
ARP can operate in either of two modes: static and dynamic. The extensions of ARP include
proxy ARP, gratuitous ARP, and ARP-Ping.
2.3 Configuring Static ARP
Static ARP indicates that there is a fixed mapping between an IP address and a MAC address.
Static ARP needs to be configured by an administrator.
2.4 Optimizing Dynamic ARP
If dynamic ARP is configured, the system automatically resolutes an IP address into an Ethernet
MAC address.
2.5 Configuring Routed Proxy ARP
Proxy ARP enables devices whose IP addresses belong to the same network segment but
different physical networks to communicate with each other.
2.6 Configuring Proxy ARP Within a VLAN
By configuring proxy ARP on a VLAN, you can interconnect isolated hosts on a VLAN.
2.7 Configuring Proxy ARP Between VLANs
By configuring inter-VLAN proxy ARP, you can interconnect hosts on different VLANs.
2.8 Configuring ARP-Ping IP
ARP-Ping IP is a method of detecting whether an IP address is used by another device on a local
area network (LAN) by sending ARP packets.
2.9 Configuring ARP-Ping MAC
ARP-Ping MAC is a method of detecting whether a MAC address is used by another device on
a LAN by sending ICMP packets.
