Configuring the Switch for Remote Management
– 47 –
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>.
Console(config)#interface vlan 1
Console(config-if)#ipv6 address FE80::260:3EFF:FE11:6700 link-local
Console(config-if)#ipv6 enable
Console(config-if)#end
Console#show ipv6 interface
VLAN 1 is up
IPv6 is enabled.
Link-local address:
fe80::260:3eff:fe11:6700%1/64
Global unicast address(es):
(None)
Joined group address(es):
ff02::1:ff11:6700
ff02::1
IPv6 link MTU is 1500 bytes
ND DAD is enabled, number of DAD attempts: 3.
ND retransmit interval is 1000 milliseconds
ND advertised retransmit interval is 0 milliseconds
ND reachable time is 30000 milliseconds
ND advertised reachable time is 0 milliseconds
ND advertised router lifetime is 1800 seconds

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.
