a probe count (default is 3), minimum TTL (default is 1), maximum TTL (default is 30), and port number
(default is 33434).

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.
