All IPv6 addresses must be 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.

command, or it can be automatically configured using the
autoconfig

If a link-local address has not yet been assigned to this interface, this command
will assign the specified static global unicast address and also dynamically
generate a link-local unicast address for the interface. (The link-local address is
made with an address prefix of FE80 and a host portion based the switch's MAC
address in modified EUI-64 format.)

If a duplicate address is detected, a warning message is sent to the console.
