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.
The switch must always be configured with a link-local address.

Therefore any configuration process that enables IPv6 functionality, or
assigns a global unicast address to the switch, including address auto-
configuration or explicitly enabling IPv6 (see

link-local unicast address. The prefix length for a link-local address 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). Alternatively, you
can manually configure the link-local address by entering the full
address with the network prefix in the range of FE80~FEBF.
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 (see "Configuring IPv6 Interface Settings" on page
It can be manually configured by specifying the entire network
prefix and prefix length, and using the EUI-64 form of the interface
identifier to automatically create the low-order 64 bits in the host
portion of the address.
