Where n is a hexadecimal number from 0 to F. The eight groups of
numbers must be separated by colons. Groups where all four digits are
“0” can be omitted. Leading “0’s” in groups can also be omitted. For
example, the following IPv6 addresses are equivalent:
12c4:421e:09a8:0000:0000:0000:00a4:1c50
12c4:421e:9a8::a4:1c50
5. To assign a prefix to the IPv6 address, enter a value in the Prefix field.
The prefix is a decimal number that represents the number of bits, from
left to right, that constitute the network portion of the address. (In an
IPv4 address, the prefix is called the subnet mask.) For example:
 The decimal mask 16 is equivalent to the prefix 255.255.0.0.
 The decimal mask 24 is equivalent to the prefix 255.255.255.0.
6. To assign an IPv6 default gateway to the switch, enter an IPv6 address
in the Default IP Gateway field.
A default gateway is an address of an interface on a router or other
Layer 3 device. It defines the first hop to reaching the remote subnets
or networks where the network devices are located. You must assign
the switch a default gateway address if the following are true:
 The remote management devices, such as Telnet workstations
and TFTP servers, are not members of the same subnet as the
IPv6 management address.
 The switch can have only one IPv6 default gateway.
 The IPv6 management address and the default gateway address
must be members of the same subnet.
For more information about the default gateway, see “IP Management
Guidelines” on page 199.
