3.4 Displaying ARP Information
Choose Local Device > Monitor > Clients > ARP List.
When two IP-based devices need to communicate with each other, the sender must know the IP address and
MAC address of the peer. With MAC addresses, an IP-based device can encapsulate link-layer frames and then
send data frames to the physical network. The process of obtaining MAC addresses based on IP addresses is
called address resolution.
The Address Resolution Protocol (ARP) is used to resolve IP addresses into MAC addresses. ARP can obtain
the MAC Address associated with an IP address. ARP stores the mappings between IP addresses and MAC
addresses in the ARP cache of the device.
The device learns the IP address and MAC address of the network devices connected to its interfaces and
generates the corresponding ARP entries. The ARP List page displays ARP entries learned by the device. The
ARP list allows you search for specified ARP entries by IP or MAC address. Click Refresh to obtain the latest
ARP entries.
