DESCRIPTION
Select Manual to manually enter a link local address. Select EUI64 to use the EUI-64
format to generate a link local address from the Ethernet MAC address.
If you selected Manual in the Link Local Address Type field, enter the LAN IPv6
address you want to assign to your Device in hexadecimal notation, for example,
fe80::1 (factory default).
Enter the address prefix to specify how many most significant bits in an IPv6 address
compose the network address.
Multicast Listener Discovery (MLD) allows an IPv6 switch or router to discover the
presence of MLD hosts who wish to receive multicast packets and the IP addresses of
multicast groups the hosts want to join on its network. Select Enabled to activate
MLD Snooping on the Device. This allows the Device to check MLD packets passing
through it and learn the multicast group membership. It helps reduce multicast traffic.
Select Manual to manually enter a LAN Identifier as the interface ID to identify the
LAN interface. The LAN Identifier is appended to the IPv6 address prefix to create the
routable global IPv6 address. Select EUI64 to use the EUI-64 format to generate an
interface ID from the Ethernet MAC address.
If you selected Manual, enter the LAN Identifier in this field. The LAN identifier should
be unique and 64 bits in hexadecimal form. Every 16 bit block should be separated by
a colon as in XXXX:XXXX:XXXX:XXXX where X is a hexadecimal character. Blocks of
zeros can be represented with double colons as in XXXX:XXXX::XXXX.
Select this option to automatically obtain an IPv6 network prefix from the service
provider or an uplink router.
Select this option to configure a fixed IPv6 address for the Device's LAN IPv6 address.
If you select static IPv6 address, enter the IPv6 address prefix that the Device uses for
the LAN IPv6 address.
If you select static IPv6 address, enter the IPv6 prefix length that the Device uses to
generate the LAN IPv6 address.
An IPv6 prefix length specifies how many most significant bits (starting from the left)
in the address compose the network address. This field displays the bit number of the
IPv6 subnet mask.
Enter the preferred lifetime for the prefix.
Enter the valid lifetime for the prefix.
Select this to have the Device send router advertisement messages to the LAN hosts.
Router advertisement is a response to a router solicitation or a periodical multicast
advertisement from a router to advertise its presence and other parameters, such as
IPv6 prefix and DNS information.
Router solicitation is a request from a host to locate a router that can act as the
default router and forward packets.
Note: The LAN hosts neither generate global IPv6 addresses nor communicate with
other networks if you disable this feature.
Select this to have the Device obtain the M/O (Managed/Other) flag setting from the
service provider or uplink router.
Select this to specify the M/O flag setting manually.
