To connect to a larger network with multiple subnets, you must
◆
configure a global unicast address. This address can be automatically
configured using this command, or it can be manually configured using
the
◆
When autoconfiguration is enabled, the network portion of the address
is based on prefixes received in IPv6 router advertisement messages
observed on the local interface, and the host portion is automatically
generated using the modified EUI-64 form of the interface identifier;
i.e., the switch's MAC address.

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.

ipv6-addr - The full IPv6 address of the switch including the
network prefix and host address bits.
ipv6-prefix - A decimal value indicating how many contiguous bits
(starting at the left) of the address comprise the prefix.

use when the management station is located on a different network
