ARP
Dell Networking OS uses two forms of address resolution: address resolution protocol (ARP) and Proxy
ARP.
ARP runs over Ethernet and enables endstations to learn the MAC addresses of neighbors on an IP
network. Over time, Dell Networking OS creates a forwarding table mapping the MAC addresses to their
corresponding IP address. This table is called the ARP Cache and dynamically learned addresses are
removed after a defined period of time.
For more information about ARP, refer to RFC 826, An Ethernet Address Resolution Protocol.
In Dell Networking OS, Proxy ARP enables hosts with knowledge of the network to accept and forward
packets from hosts that contain no knowledge of the network. Proxy ARP makes it possible for hosts to
be ignorant of the network, including subnetting.
For more information about Proxy ARP, refer to RFC 925, Multi-LAN Address Resolution, and RFC 1027,
Using ARP to Implement Transparent Subnet Gateways.
Configuration Tasks for ARP
For a complete listing of all ARP-related commands, refer to the Dell Networking OS Command Line
Reference Guide.
