Command Usage
•
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
on page 1052), will also automatically generate a 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 a 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”
•
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.
