Select “AUTO” from the IPv6 pull-down list, a link-local or router-

assigned address will be available after a system reset.

IPv6 addresses can be acquired through the following ways:

• A link-local address is automatically configured by entering

AUTO in the IPv6 address field. With a point-to-point connection

without router, addresses will be generated using port MAC

addresses starting with the “fe80::” bits. Link-locals are

addresses within the same subnet.

• If addresses are automatically acquired, the “Subnet prefix

length” and the “Route” fields can be left blank.

• A DHCPv6 server, if present in the network, will be automatically

queried for an IPv6 address.

• If an IPv6 router is present, you can Key in AUTO in the Route

field and let a router’s advertisement mechanism determine

network addresses.

• You can also manually enter IPv6 addresses by selecting Static

from the pull-down list and then enter an IP. You may generate

the last 64 hexadecimal bits from the 48-bit MAC addresses of

Ethernet ports in EUI-64 format, and then use the combination of

fe08 prefix and prefix length to signify a subnet.

A sample process is shown below: 1. Insert FFFE between

company ID and node ID, as the fourth and fifth octets (16 bits).

2. Set the Universal/Local (U/L) bit, the 7

of the first octet, to a

value of 0 or 1. “0” indicates a locally administered identity, while

“1” indicates a globally unique IPv6 interface ID.

Galaxy supports a variety of IPv6 mechanisms including Neighbor

Unreachability Detection, stateful and stateless address

autoconfiguraion, ICMPv6, Aggregatable Global Unicast Address,

Neighbor Discovery, etc.
