64.12 DHCPv6 Prefix Delegation

Prefix delegation enables an IPv6 device to use the received IPv6 prefix (for example, '2001:db2::/48') to
generate its IP address. The Switch passes the IPv6 prefix information to its connected hosts (according
to VLAN) so that they can generate their IPv6 addresses.
Use this screen to view and configure DHCPv6 client and IPv6 prefix settings for a specific VLAN on the
Switch. Click NETWORKING > DHCP > DHCPv6 Server > DHCPv6 Server Prefix Delegation to display the
screen as shown.

DESCRIPTION
Enable the switch button to enable the entry.
Enter the ID number of the VLAN to which the DHCPv6 server belongs here.
Enter the number of seconds a DHCPv6 client should wait before refreshing information retrieved
from a DHCPv6 server. The allowed range is 600 to 4294967295 seconds.
Specify the IPv6 address of the DNS server for the DHCP clients to use here.
An 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This
is an example IPv6 address '2001:0db8:1a2b:0015:0000:0000:1a2f:0000'.
IPv6 addresses can be abbreviated in two ways:
• Leading zeros in a block can be omitted. So '2001:0db8:1a2b:0015:0000:0000:1a2f:0000'
can be written as '2001:db8:1a2b:15:0:0:1a2f:0'.
• Any number of consecutive blocks of zeros can be replaced by a double colon. A double
colon can only appear once in an IPv6 address. So
'2001:0db8:0000:0000:1a2f:0000:0000:0015' can be written as
'2001:0db8::1a2f:0000:0000:0015', '2001:0db8:0000:0000:1a2f::0015', '2001:db8::1a2f:0:0:15'
or '2001:db8:0:0:1a2f::15'.
Click Apply to save your changes to the Switch's run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to save
your changes to the non-volatile memory when you are done configuring.
Click Clear to clear the fields to the factory defaults.
Click Cancel to not save the configuration you make and return to the last screen.
DESCRIPTION
This field displays a sequential number for each entry.
This field displays the client DHCP Unique IDentifier (DUID) which uniquely identifies the client.
This field displays a name to identify the DHCPv6 client.
