Address for Multi-segment Network — 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:
◆ Prefix for this network
◆ IP address for the switch
◆ Default gateway for the network
For networks that encompass several different subnets, you must define
the full address, including a network prefix and the host address for the
switch. You can specify either the full IPv6 address, or the IPv6 address
and prefix length. The prefix length for an IPv6 network is the number of
bits (from the left) of the prefix that form the network address, and is
expressed as a decimal number. For example, all IPv6 addresses that start
with the first byte of 73 (hexadecimal) could be expressed as
73:0:0:0:0:0:0:0/8 or 73::/8.
To generate an IPv6 global unicast address for the switch, complete the
following steps:
1. From the global configuration mode prompt, type “interface vlan 1” to
access the interface-configuration mode. Press <Enter>.
2.
From the interface prompt, type “ipv6 address ipv6-address” or
“ipv6 address ipv6-address/prefix-length,” where “prefix-length”
indicates the address bits used to form the network portion of the
address. (The network address starts from the left of the prefix and
should encompass some of the ipv6-address bits.) The remaining bits
are assigned to the host interface. Press <Enter>.
