IEWING
The ARP cache is a table maintained locally in each station on a network. ARP cache entries are learned by examining the
source information in the ARP packet payload fields, regardless of whether it is an ARP request or response. Thus, when
an ARP request is broadcast to all stations on a LAN segment or virtual LAN (VLAN), every recipient has the opportunity to
store the sender's IP and MAC address in their respective ARP cache. The ARP response, being unicast, is normally seen
only by the requestor, who stores the sender information in its ARP cache. Newer information always replaces existing
content in the ARP cache.
The ARP cache can support 1024 entries, although this size is user-configurable to any value less than 1024. When multiple
network interfaces are supported by a device, as is typical of a router, either a single ARP cache is used for all interfaces,
or a separate cache is maintained per interface. While the latter approach is useful when network addressing is not unique
per interface, this is not the case for Ethernet MAC address assignment so a single ARP cache is employed.
