◆
The ARP cache is used to map 32-bit IP addresses into 48-bit hardware
(i.e., Media Access Control) addresses. This cache includes entries for
hosts and other routers on local network interfaces defined on this
router.
◆
The maximum number of static entries allowed in the ARP cache is 256.
◆
You may need to enter a static entry in the cache if there is no response
to an ARP broadcast message. For example, some applications may not
respond to ARP requests or the response arrives too late, causing
network operations to time out.
◆
Static entries will not be aged out nor deleted when power is reset. A
static entry can only be removed through the configuration interface.
