ARP

Dell Networking OS uses two forms of address resolution: address resolution protocol (ARP) and Proxy

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.

For a complete listing of all ARP-related commands, refer to the Dell Networking OS Command Line

Reference Guide.
