the undefined fields. For detailed information on the other ways to assign IPv6
addresses, see "Setting the Switch’s IP Address (IP Version 6)" on page 4-9.
Link Local Address — All link-local addresses must be configured with a prefix of
FE80. Remember that this address type makes the switch accessible over IPv6 for
all devices attached to the same local subnet only. Also, if the switch detects that the
address you configured conflicts with that in use by another device on the subnet, it
will stop using the address in question, and automatically generate a link local
address that does not conflict with any other devices on the local subnet.
To configure an IPv6 link local 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.
Type “ipv6 address” followed by up to 8 colon-separated 16-bit hexadecimal
values for the
ipv6-address
similar to that shown in the example, followed by
the “link-local” command parameter. Then press <Enter>.
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 most networks that encompass several different subnets, it’s easier to first
define a network prefix, and then configure the host address for the switch. An IPv6
network prefix is composed of an IPv6-address and prefix length. The prefix length
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 address 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.
