• Dynamic Only—Deletes the dynamic hosts.
• All Dynamic & Static—Deletes the static and dynamic hosts.
The Host Mapping Table displays the following fields:
• Host Name—User-defined host name or fully-qualified name.
• IP Address—The host IP address.
• IP Version—IP version of the host IP address.
• Type—Is this a Dynamic or Static entry to the cache.
• Status— Displays the results of attempts to access the host
- OK—Attempt succeeded.
- Negative Cache—Attempt failed, do not try again.
- No Response—There was no response, but system can try again in future.
• TTL (Sec)— If this is a dynamic entry, how long will it remain in the cache.
• Remaining TTL (Sec)— If this is a dynamic entry, how much longer will it remain in
the cache.

• IP Version—Select Version 6 for IPv6 or Version 4 for IPv4.
• IPv6 Address Type—Select the IPv6 address type (if IPv6 is used). The options are:
- Link Local—The IPv6 address uniquely identifies hosts on a single network link. A
link local address has a prefix of FE80, is not routable, and can be used for
communication only on the local network. Only one link local address is supported.
If a link local address exists on the interface, this entry replaces the address in the
configuration.
