IP Routing
19-12

CLI -
This example sets a static entry for the ARP cache.
Displaying Dynamically Learned ARP Entries
The ARP cache contains entries that map IP addresses to the corresponding
physical address. The ARP cache contains static entries, and entries for local
interfaces, including subnet, host, and broadcast addresses. Most of these entries will
be dynamically learned through replies to broadcast messages. You can display all of
the dynamic entries in the ARP cache, change specific dynamic entries into static
entries, or clear all dynamic entries from the cache.
Command Attributes
•
IP Address

•
MAC Address

•
Interface

Type
– Indicates if entries were learned through replies to broadcast messages,
are statically configured entries, or are other entries for local interfaces (including
subnet and broadcast addresses).
