Gratuitous ARP Settings

An ARP announcement (also known as Gratuitous ARP) is a packet (usually an ARP Request) containing a valid SHA and SPA
for the host which sent it, with TPA equal to SPA. Such a request is not intended to solicit a reply, but merely updates the ARP
caches of other hosts which receive the packet.
This is commonly done by many operating systems on startup, and helps to resolve problems which would otherwise occur if, for
example, a network card had recently been changed (changing the IP address to MAC address mapping) and other hosts still had
the old mapping in their ARP cache

Description
The IPv6 address and corresponding Prefix Length of the IPv6 static route entry.
The IP Interface where the static IPv6 route is created.
The corresponding IPv6 address for the next hop Gateway address in IPv6 format.
The metric of the IPv6 interface entered into the table representing the number of
routers between the Switch and the IPv6 address above. Metric values allowed are
between 1 and 65535.
Represents the status for the IPv6 routing table entry.
Displays whether the entry is Active or Inactive.

Description
The IP Interface where the static IPv6 route is to be created.
Specify the address and mask information using the format as IPv6 address / prefix length
(IPv6 address is hexadecimal number, prefix length is decimal number, for example
1234::5D7F/32).
Clicking the default check box will set the IPv6 address as unspecified and the Switch will
automatically find the default route. This defines the entry as a 1 hop IPv6 default route.
Enter the IPv6 address for the next hop Gateway address in IPv6 format.
The metric representing the number of routers between the Switch and the IPv6 address
above.
