SAGE UIDELINES
All IPv6 addresses must be formatted according to RFC 2373 "IPv6
◆
Addressing Architecture," using 8 colon-separated 16-bit hexadecimal
values. One double colon may be used in the address to indicate the
appropriate number of zeros required to fill the undefined fields.
When configuring a link-local address, note that the prefix length is
◆
fixed at 64 bits, and the host portion of the default address is based on
the modified EUI-64 (Extended Universal Identifier) form of the
interface identifier (i.e., the physical MAC address). You can manually
configure a link-local address by entering the full address with the
network prefix FE80.
To connect to a larger network with multiple subnets, you must
◆
configure a global unicast address. There are several alternatives to
configuring this address type:
The global unicast address can be automatically configured by
■
taking the network prefix from router advertisements observed on
the local interface, and using the modified EUI-64 form of the
interface identifier to automatically create the host portion of the
address. This option can be selected by enabling the Auto
Configuration option.
You can also manually configure the global unicast address by
■
entering the full address and prefix length.

The following parameters are displayed on the IPv6 & Time page:
IPv6 Configuration
Auto Configuration – Enables stateless autoconfiguration of IPv6
◆
addresses on an interface and enables IPv6 functionality on the
interface. The network portion of the address is based on prefixes
received in IPv6 router advertisement messages, and the host portion
is automatically generated using the modified EUI-64 form of the
interface identifier; i.e., the switch's MAC address. (Default: Disabled)
Address – Manually configures a global unicast address by specifying
◆
the full address and network prefix length (in the Prefix field).
(Default: ::192.168.2.10)
Prefix – Defines the prefix length as a decimal value indicating how
◆
many contiguous bits (starting at the left) of the address comprise the
prefix; i.e., the network portion of the address. (Default: 96 bits)
Note that the default prefix length of 96 bits specifies that the first six
colon-separated values comprise the network portion of the address.
