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 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>.
3. Type “exit” to return to the global configuration mode prompt. Press <Enter>.
4. To set the IP address of the IPv6 default gateway for the network to which the switch belongs,
type “ipv6 default-gateway gateway,” where “gateway” is the IPv6 address of the default
gateway. Press <Enter>.
