ASSIGNING AN IPV6 ADDRESS
This section describes how to configure a “global unicast” address by
specifying the full IPv6 address (including network and host portions) and
the length of the network prefix.
An IPv6 address must be formatted according to RFC 2373 “IPv6
Addressing Architecture,” using 8 colon-separated 16-bit hexadecimal
values. One double colon may be used to indicate the appropriate number
of zeros required to fill the undefined fields.
Before you can assign an IPv6 address to the switch that will be used to
connect to a multi-segment network, you must obtain the following
information from your network administrator:
◆ IP address for the switch
◆ Length of the network prefix
◆ Default gateway for the network
When configuring the IPv6 address and gateway, one double colon may be
used to indicate the appropriate number of zeros required to fill the
undefined fields. To generate an IPv6 global unicast address for the switch,
type the following command, and press <Enter>.
“ip ipv6 setup ipv6-address ipv6-prefix ipv6-router vid”
where “ipv6-address” is the full IPv6 address of the switch including the
network prefix and host address bits. “ipv6-prefix” indicates the length of
the network prefix, “ipv6-router” is the IPv6 address of the default next
hop router to use when the management station is located on a different
network segment, and “vid” is the VLAN identifier for the interface to which
this address will be assigned.
