Command Usage
• The ARP cache is used to map 32-bit IP addresses into 48-bit hardware
(that is, 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 128.
• A static entry may need to be entered 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.
